Somalia Rainfall Forecast – Issued 19 May 2022
In the last two weeks there has been a significant reduction of rainfall across Somalia except for a few places along the southern coast. Generally, the seasonal rains have been low in parts of the country, while in other parts localized heavy storms were experienced within a few days, resulting to flash floods such as Las Anod in Sool Region, Ceerigabo in Sanaag, and Jedaal/Ufeyn in Bari Region.
The cumulative rainfall forecast for the next seven days shows light rains along the coastal areas of Lower Juba. Scattered light rains are also expected in parts of the central and southern regions. Most parts of Somaliland and Puntland will remain dry within the coming week. In the Ethiopian highland where Juba and Shabelle Rivers originate light rains are expected within the same period.
It is worth noting that the Gu 2022 rainy season started late in Somalia, and the rainfall amounts recorded so far are below normal in many parts of the country, with poor temporal and spatial distribution. More rains are required to alleviate the current drought conditions. With no significant rains foreseen as the season comes to an end, the existing drought situation may deteriorate further in all the water dependent sectors.
River levels along the Juba and Shabelle reduced over the last one week, and the trend is expected to continue in the coming week, given the rainfall forecast.

Somalia Rainfall Forecast – Issued 25 May 2022
The last two weeks have seen a significant reduction of rainfall across Somalia marking a possible early end of the Gu 2022 rainfall season. There is cause for concern as observed rainfall records indicate that some parts in the central regions of Galmudug as well as Bari and Nugaal regions in Puntland received minimal rains since the start of the season. Cumulatively, the rainfall amounts recorded so far are below average with a typical poor distribution in space and time. This marks the fourth consecutive failed rainy season in Somalia, a situation that has not been witnessed in the recent history.
According to current climate model (https://iri.columbia.edu/our-expertise/climate/forecasts/enso/current/), indicate there is 62 per cent (62%) chance of the La Nina phenomena during the June to August 2022 period. The phenomena is largely associated with drier than normal periods in the country. With no significant rains foreseen as the season comes to an end and the La Nina predictions, the existing drought situation will deteriorate further in Somalia.
The cumulative rainfall forecast for the next seven days is calling for a further reduction of the seasonal rains with light rains expected in pockets of a few regions. In the same period moderate to low rains are expected in the upper parts of the Ethiopian highlands.
River levels along the Juba and Shabelle reduced over the last one week, and the trend is expected to continue in the coming week, given the rainfall forecast.

Somalia Rainfall Forecast – Issued 13 April 2022
The Gu rains which started in the second half of March 2022 in parts of Somalia were followed by a prolonged dry period of more than 15 days making the rains ineffective. The prolonged dry period led to a significant water deficit further deteriorating the drought conditions. The last two days have seen scattered light rains in a few places in the southern parts of the country while the northern parts remained dry.
The cumulative rainfall forecast for the coming week indicates light to moderate rains in the southern and central regions as well as within the Ethiopian highlands. Light rains are foreseen in pockets of the northern regions during the forecast period
It is worth noting that, the foreseen rains in the coming week are not sufficient to alleviate the current drought conditions in the country, more rains with good temporal and spatial distribution are required during the season in order to improve the situation.
River levels along the Juba and Shabelle are still within the historical minimum and are expected to start increasing at the end of the April given the rainfall forecast.

Somalia Rainfall Forecast – Issued 25 March 2022
In the last 24 hours, a few places in Somalia received light to moderate rains marking a possible start of the Gu rain season. Galdogob and Galckaayo in the central areas recorded 37 mm and 14 mm respectively. Field reports also indicate that there was moderate rains in parts of Bay and Bakool regions during the same period.
It is worth noting that, the foreseen rains in the coming week are not sufficient to alleviate the current drought conditions in the country, more rains with good temporal and spatial distribution are required during the season in order to improve the situation.
The cumulative rainfall forecast for the coming week indicates a continuous spread of rains in the southern and central regions. No rains are foreseen in the northern regions during the forecast period. In the Ethiopian highland, whose rainfall is largely responsible for increase in river flow along the Juba and Shabelle Rivers inside Somalia, light to moderate rainfall is foreseen in the coming week.
River levels along the Juba and Shabelle are still within the historical minimum and are expected to start increasing in April given the rainfall forecast.

Somalia Drought Update & April 2022 Rainfal Outlook
The latest rainfall forecast from ICPAC is now indicating that below normal rains are expected in the country during April. Forecasts from other sources also show higher chances of below normal rains in Southern Somalia and normal rains in the rest of the country for the period April through June. Given forecast La Nina conditions which are expected to persist in April, ongoing drought in Somalia will worsen in April and possibly continue at least through mid-2022. Worst affected areas will be central and southern parts of the country. SWALIM’s drought monitoring based on field reports and the Combined Drought Index indicates that, currently, about 80% of the country is facing extreme drought conditions.
This has continued to cause loss of livestock and human suffering. Water shortage is widespread. Water and food prices remain high and continue to rise in many areas. Preliminary results from an ongoing survey of boreholes in Puntland indicates that water trucking is on the rise with some boreholes serving more than 15 trucks per day. This has in turn led to extended pumping hours where over 60% of them are operating for more than 12 hours in a day.
There has been a wide disruption of normal activities in some areas where children have stopped going to school. The lack of water and pasture for livestock has impacted negatively to the animal conditions with livestock deaths increasing in many areas and an increasing proportion of the surviving ones being in very weak conditions.
Juba and Shabelle river levels continued to decrease during the month of March. The graphs in Figure 2 & 3 show comparison of 2021/22 and the short term mean (2002 to 2022) for Shabelle and Juba river levels at Belet Weyne and Luuq stations, respectively. Current river levels are lower than the short term mean for both stations. Irrigated agriculture in the lower reaches of the two rivers have been seriously hampered by the low river levels . At Luuq along the Juba river in Gedo region, the unprecedented low river levels has exposed the dry river bed.
According to the revised March to May 2022 seasonal forecast issued by IGAD Climate Prediction and Application Center (ICPAC) on 28 March 2022, there is a greater likelihood of below average rainfall in April 2022 in the southern pars of Somalia as well as the adjacent Ethiopian highlands as shown on Map 2.
High temperatures are expected during the same month of April. High temperatures will lead to increased evaporation and increased demand for water among livestock, leading to worsening drought conditions. Following the failure of three consecutive rainy seasons since October 2020, and forecast below average 2022 Gu season rainfall, the cumulative effect will likely lead to extended and worsening drought conditions in Somalia.
The seasonal rains started in the last week of March in some southern and a few places in the north, briefing a temporary relief to these areas. Drought condition will likely persist and could even worsen unless the rains continue in the coming weeks and months. While current forecasts indicate a likely below average March to May 2022 Gu season rainfall, flash floods or extended dry periods may occur in some areas. SWALIM will keep updating this forecast for shorter lead time and will share with you through regular bulletins throughout the rainfall season.

Somalia Drought Update & GU 2022 Rainfall Outlook–Issued March 2022
Many parts of the country remained generally dry throughout the month of February 2022 leading to persistence of drought conditions. Pasture and water are in extremely poor conditions and close to a complete depletion in key pastoral livelihoods across Somalia. Severe water crises has resulted to increased water trucking and prices, which pastoral and agro pastoral households meet through increased debt accumulation and/or livestock sales. Current drought conditions are expected to worsen until the start of Gu season rainfall in April.
The high demand for water is overstretching the few functional permanent water sources in the country. Preliminary results from the ongoing SWALIM water sources survey across the country indicate 15 to 24 pumping hours per day for many boreholes. Body condition of small ruminants and cattle has deteriorated to poor and very poor conditions, leading to death of offspring (calves, kids, lambs) as well as lactating animals due to prolonged drought conditions. Livestock migration options remain limited due to exhausted rangelands and weak body conditions. Current river levels along the Juba and Shabelle rivers are currently below their historical minimum, with dry riverbeds observed in many sections of the two rivers. This conditions will get worse until the start of Gu season rainfall in April.

Status of river breakages along the Juba and Shabelle Rivers in Somalia – February 2022
Three consecutive poor rainy seasons within the Juba and Shabelle River basins inside Somalia and the Ethiopian highlands have led to the current serious hydrological drought along the two rivers. The river levels in the upper sections are currently at their historical minimum, while the mid and lower sections of the Shabelle River having run dry. With no rains expected in February and most of March, the river flow will continue to decline.
The reduced river flow along the two rivers has negatively impacted agriculture production, domestic and livestock water use. This has also led to an increase of new river breakages as the riverine communities attempt to extract the limited resource to support livelihood activities.
SWALIM has completed analysis and mapping of the river breakages along the two rivers using very high resolution satellite images acquired thanks to the kind contribution of the Embassy of France. The study has identified 101 open points along the Shabelle, out of which 24 points are new and the rest have remained open since the last survey in August 2021. Along the Juba River, 35 open points were identified out of which 5 are new points. During this drought period, it is expected that the riverine communities will continue to extract water from the rivers by breaching the banks and this will only see an increase of the open river bank points.
Several other weak points which are not necessarily open but have the potential to overflow or break were identified during the analysis. This information is available in the SWALIM Flood Risk and Response Information Management System (http://frrims.faoswalim.org/rivers/breakages).
It is worth noting that since the last survey in August 2021, several agencies including FAO have made efforts to close about 23 of the open river banks and reinforced about 37 of weak river embankments that could otherwise flood when river levels rise.
With the Gu rains expected in April 2022, the rise in river levels will consequently lead to floods resulting from the existing open river bank points and weak river embankments. It is therefore advisable to close the open points and reinforce the weak points before the start of the Gu season to avoid the negative impacts of riverine flooding.
The methodology heavily relied on satellite imageries with limited field verification. Open breakages might have been omitted in some cases due to cloud cover or vegetation cover along the embankments

Somalia Drought Update - Issued 27 January 2022
The poor rains during the last three consecutive seasons (October 2020 to December 2021) have caused widespread and worsening drought conditions across most parts of Somalia. This has resulted in failed crop harvests, widespread water shortage, triggering abnormal livestock migration, decline in livestock production and increased livestock deaths. Water and food prices have continued to rise sharply.
Since December 2021 the drought severity has notably worsened. As of January 2022, most parts of the country are experiencing Severe drought conditions, with Jubaland and central regions and adjacent areas already in Extreme drought. Somaliland, which was previously less affected is now experiencing Moderate to Severe drought conditions following an influx of both humans and livestock and a rapid depletion of rangeland conditions.

Somalia Drought Update – Issued 22 December 2021
Drought severity in Somalia has continued to worsen following prolonged dry period characterized by high temperatures.
The drought conditions in Jubaland in southern parts of the country have deteriorated from severe to extreme. Other areas that were experiencing mild drought conditions in the north are now facing moderate levels of drought with the situation expected to get worse.
Wells are drying up rapidly while the river levels along the Juba and Shabelle continue to decrease at an alarming rate.
Currently, more than 90 percent of the country is experiencing drought conditions at different severity magnitudes with the southern and central parts being worst affected.
Pasture and water came to a complete depletion in many areas leaving about 169,000 in displacement as of today (OCHA—2022 Drought Response Plan Report).
Drought conditions are expected to worsen during the first quarter of 2022 with possibility of extending to the second quarter due to extended impacts.

Somalia Drought Update – Issued 18 November 2021
The impacts of Climate Change and variability in Somalia are the major causes of current climatic hazards that have been facing the country over the last 10 years. In 2018 and 2019 the country experienced heavy rains leading to massive flooding and associated negative impacts. This was followed by poor rains in Dyer 2020, Gu 2021 and the ongoing Deyr season.
Currently, more than 80% of the country is experiencing severe drought conditions following a third consecutive failed rainfall season. This has led to serious human suffering.
Water trucking, migration of populations and livestock has become rampant in many areas leading to quick depletion of the limited resources.
The Juba and Shabelle river levels are low and are expected to decrease further in the coming months. Likewise, most berkads and shallow wells have dried up leaving the communities to rely on boreholes which are far apart and some with low yield and poor quality especially in Puntland and the central regions.
With crop failure expected in most of the agricultural areas the prospects for Deyr season cereal production remain bleak.
The rainfall forecast for the second half of November indicates depressed rains in the country which will not be effective in mitigating the drought conditions.
Drought conditions are expected to worsen in December 2021 and the first quarter of 2022 leading to a similar situation witnessed in 2017.

Somalia Rainfall Forecast – Issued 24 November 2021
The last 2 weeks have been characterized by a reduction of rains across Somalia and the Ethiopian highlands. Many stations did not record any rainfall within that period. This raised a lot of concerns as an early cessation of the Deyr season would make worse the drought conditions currently experienced in many parts of the country.
The rainfall forecast for the next one week is however promising, especially in the southern regions. The 3—7 days cumulative rainfall forecast (Maps 1 and 2) shows moderate rains spread across the southern regions of the country, with parts of Bay and Lower Shabelle receiving heavy rainfall. The central and northern regions are expected to receive scattered light to moderate rains for the same period. Inside Ethiopia, the Juba and Shabelle catchment, where most of flow in the two rivers originate, moderate to heavy rainfall is foreseen towards the end of the week.
Along the Puntland coast there has been fears of experiencing a cyclone within today. Recent updates however indicate that the area of convection has since dissipated, reducing the possibility of a significant tropical cyclone developing. The coastal areas of Bari may however experience strong winds and showers in the next few days, but at a much lower magnitude compared to a tropical cyclone.
River levels along Juba and Shabelle remains low, and within normal for this time of the year.

Somalia Rainfall Forecast – Issued 04 October 2021
The 2021 Deyr rains have kicked off in parts of Somalia. The northern regions of Somaliland and Puntland recorded moderate amounts of rainfall during the last one week. Notably, Baran station in Sanaag region recorded a total of 230 mm over the last one week while Las Canood received 76 mm during the same period. The rains are expected to continue spreading in time and space during this month.
Most parts of Somaliland recorded good rains during the months of August and September.
The cumulative rainfall forecast for this week indicates significant spread of the rains within the northern parts of the country. The central and southern parts of the country will remain dry during the forecast period with the rains expected to start in the second half of October. In the Ethiopian highlands, whose rainfall is largely responsible for increase in river flow along the Juba and Shabelle Rivers inside Somalia, moderate to high rainfall is foreseen in the coming one week.
It is worth noting that, the foreseen rains in the coming week are not sufficient to alleviate the current drought conditions in the country, more rains with good temporal and spatial distribution are required during the season in order to improve the situation.
River levels along the upper reaches of both Juba and Shabelle increased over the last few days, but remains within the normal for this period of the year. Given the rainfall forecast, a slight increase in the levels for both rivers is expected with no risk of flooding over the next seven days.

Somalia Rainfall Forecast – Issued 11 October 2021
Moderate to heavy rains were observed in parts of Puntland during the last few two days. The good rains came as an immediate relief to the drought stricken areas following the failure of two consecutive rainy seasons. More rains will however be required to alleviate the water stress in Puntland and other parts of the country. On the negative side, the heavy rains led to flashfloods and consequently, loss of property and livestock death in Bari region.
The cumulative rainfall forecast for the next seven days shows continuous spread of the Deyr rains in the central and southern areas of the country. There will be a reduction of rainfall activities in Somaliland and most parts of Puntland with an exception of Nugaal region that will see moderate rains within the week. In the Ethiopian highlands, whose rainfall is largely responsible for increase in river flow along the Juba and Shabelle Rivers inside Somalia, moderate to high rainfall is foreseen in the coming one week.
River levels along the upper reaches of both Juba and Shabelle continued to increase since the last update last week. The levels are however within the normal for this period of the year. The increasing trend will continue given the rainfall forecast with no risk of flooding over the next seven days.

Somalia Drought Update – Issued 18 October 2021
The Deyr 2021 rains kicked off in parts of Somalia with moderate rains being observed in Puntland ( Bari region) and a few pockets in the southern regions. However, more than half of the country is still experiencing serious drought conditions.
The Southern parts of the country that had remained in moderate drought conditions in the previous months are now facing moderate to severe drought due to further depletion of the limited resources in the areas. This has led to serious human suffering and livestock death.
Drought impacts are worse in Jubaland, Southwest state, GalMudug ( central regions) and parts of Puntland which have suffered from consecutive seasons of poor rainfall. Water resources and pasture conditions have deteriorated in these areas triggering livestock migration and increased competition among pastoralists on the already limited resources.
The rainfall forecast for the second half of October indicates depressed rains in the south and central regions while the northern regions will record within normal rains. In November, the will subside in the northern areas and increase in the southern areas.
Further, the Deyr 2021 seasonal rainfall is expected to be cumulatively below average in many parts of Somalia according to ICPAC.
Given the rainfall forecast, the depressed rains are not going to be effective in mitigating the drought conditions
A return to normal rainfall patterns and in good amounts is necessary for drought conditions to be reversed. Short and intensive rains are not effective in mitigating the drought conditions, as they trigger floods (damaging the crops and washing away the upper fertile layer of soil) but does not give enough time for the water to infiltrate in the ground and improve crop germination and development.

Somalia Rainfall Forecast – Issued 28 October 2021
The Deyr seasonal rains continued to spread in across Somalia over the last week although the amounts were low. There was notably a significant reduction of rainfall amounts in Puntland and Somaliland over the same period. Further, it is worrying to note that many parts of the southern regions which are facing serious drought conditions, have not yet received the much awaited seasonal rains.
The cumulative rainfall forecast for the next seven days shows continuous spread of the Deyr rains with light to moderate intensities in parts of the northern regions, Hirshabelle, Bay and Bakool regions. Most of the central and Jubaland regions will receive minimal rains during the forecast period. In the Ethiopian highlands, whose rainfall is largely responsible for increase in river flow along the Juba and Shabelle Rivers inside Somalia, light to moderate rainfall is foreseen in the coming one week.
River levels along the upper reaches of both Juba and Shabelle continued to increase over the last one week. The levels are however within the normal for this period of the year. The increasing trend will continue given the rainfall forecast with no risk of flooding over the next seven days.
Users are advised that this is a forecast and at times there may be discrepancies between estimates and actual amounts of rainfall received. Information on the forecast and observed river levels is updated daily and can be found on this link: http://frrims.faoswalim.org.

Flood Update for Jowhar District – Issued 16 August 2021
Observed levels of the Shabelle River in Somalia have been rising for the past two weeks. This has been attributed to moderate rains in the upper parts of the Ethiopian highlands. Currently, river levels at the upper reaches inside Somalia (Hiraan Region at Belet Weyne and Bulo Burti), are slightly above the normal range, while the mid and lower reaches (Middle and Lower Shabelle regions) are significantly above the normal levels at this time of the year. This has resulted in over bank spillage leading to riverine floods in parts Middle Shabelle. Further, two open river breakages in Jowhar district located in Bodale and Halgan village which are 22 km and 8 km south of Jowhar town respectively, have led to massive flooding in the area since 14 August 2021. According to field reports, several households have been affected and hundreds of crop destroyed.
The rainfall forecast for the coming week (16 to 22 Aug 2021) is pointing towards moderate rains within the upper parts of the Ethiopian highlands. Given the forecast, river levels are expected to continue rising further in the coming week .
Therefore, the flooding in Jowhar is high likely to be sustained throughout the week. Other areas to watch include riverine towns in the lower Shabelle region. Preliminary results from analysis of current status of river breakages along the Shabelle River by SWALIM indicate that there are several open and weak points and this could further exacerbate the flood situation. An updated database of the river breakages will be shared within a week.

Somalia Drought Update – Issued 26 August 2021
The failure of Dery 2020 (Oct- Dec) rainy season followed by a by a harsh and warmer than normal Jan-Mar Jilaal season, and a poorly distributed Gu 2021 (Mar/Apr-Jun) rainy season have led to mild to moderate drought conditions in some parts of Somalia.
The southern parts of the country including the Middle juba, Gedo and parts of Bay and Bakool have been worst affected and are experiencing moderate drought conditions.
River levels along the Juba and Shabelle rivers remained significantly below average since Mid-June and started to rise at the beginning of August following moderate rains in the upper parts of the Ethiopian highlands.
Preliminary rainfall forecast for the coming months indicates dry conditions throughout August and September in most parts of the country except Awdal region and southern coastal areas that will continue to receive the Karan rains.
According to the seasonal outlook by IGAD Climate Prediction and Application Centre (ICPAC), the Deyr 2021 rainy season is expected to be below average in most parts of the country.
Mild to moderate drought conditions are expected to persist in many parts of the country until early 2022 given the current situation and the Deyy 2021 rainfall outlook.
Drought Severity Analysis
FAO SWALIM’s Combined Drought Index (CDI) has been used to measure the magnitude and severity of drought in Somalia and it is based on remotely-sensed data of vegetation cover, temperature and rainfall. CDI analyses were complemented with field reports, including water prices, livestock and crop conditions to generate a drought severity map for the month of August 2021 (Map 1). Vegetation conditions anomaly as of 10 August are displayed in Map 2 while Figures 1 to 4 show analysis from January to July 2021. Each value in the graphs represents the persistence of dry conditions (average) in the preceding six months. The graphs demonstrate a downward trend of the index in southern regions implying that the situation has deteriorated from the previous months while an upward trend is noted in the northern regions due to improved conditions following heavy rains in May 2021.

Somalia River Breakages Update – August 2021
Recurrent flooding along the Juba and Shabelle Rivers in Southern Somalia has been one of the key challenges for the riverine communities. The last 10 years have seen more than six major flood events including in; 2010, 2013, 2015, 2018, 2019 and 2020. The last three events had magnitudes larger than the one associated with the historical 50-year return period flood occurrence. Such sequential events have had hazardous impacts, eroding resilience, economic reserves, health and livelihoods. Flooding and the associated effects along the two rivers has damaged vast farmland with crops and infrastructure. Soil erosion as a results of poor watershed management has gradually led to deposition of sediment into the two rivers, causing the infilling of the riverbeds and consequently raising it. For instance, in Jowhar, in Middle Shabelle, the river bed raised by close to 1.0 m since 2015. This leads to reduced capacity of the river channel and over bank spillage in flows much lower than expected.
SWALIM has been mapped twice a year the river breakages along the two rivers since 2015. This had been made possible with the use of World View Very High-Resolution (VHR) satellite imagery provided by Digital Globe. Due to lower temporal resolution of images present in Digital Globe archive, Pleiades Images provided by Airbus supplemented the image gaps in some areas. Where possible the preliminary findings from the images were verified with field observations to confirm the status of river breakages. In this case, the field river breakages surveys were carried out in Belet Weyne, Jowhar, Balcad and Afgooye districts all along the Shabelle River. In other cases, breakages which had been verified on VHR in March 2021 and there was either cloudy images or no images at all in the current assessment have been marked as ‘Not verified’.
Along the Juba River, 32 open points, 6 overflows and another 123 potential breakages and 75 potential overflows were identified. Further, 103 open points, 106 overflows and 103 potential breakages and 322 potential overflows were identified along the Shabelle River.
It has been observed that the number of points either open or overflows has been increasing over the years probably due to the continuous weakening of the river banks following three years of successive heavy floods in 2018, 2019 and 2020. These points need immediate closure or reinforcement before the 2021 Deyr rainy season which is expected to start in Mid-October 2021.

Rainfall Performance Gu 2021 (March-June)
The 2021 Gu rainy season performance varied across Somalia with many places recording average to below average rainfall (Maps 1 & 2, and Annex I). The seasonal rains which started in late April lasted for three weeks and came to an early end during the first week of May 2021. During the three weeks of rainfall, some places recorded heavy rains that led to flash floods in the northern parts of the country. The southern regions recorded below normal seasonal rains, leaving many places under water stress. This follows another poor rainfall performance during the 2020 Deyr (October-December) season which led to moderate drought conditions this year that lasted till late April.
Map 1 shows the cumulative rainfall amounts for March to May, while Map 2 shows a comparison of the seasonal rainfall with the long term mean for the same period both based on satellite rainfall estimates data. Both maps indicate varied rainfall performance during 2021 Gu. Positive cumulative anomalies are observed in a few places within Somaliland and localized areas in Nugaal, Mudug and Gedo regions while widespread negative anomalies are seen in most of the northern, central and southern regions of Somalia.
Heavy rains in the Ethiopian highlands led to increased river flow along the Juba and Shabelle rivers leading to riverine flooding in some areas. New and unrepaired open breakages on embankments of the Shabelle river also contributed to river flooding especially in Belt Weyne and Jowhar districts.
The suppressed rains in the southern parts of the country and a few pockets of Puntland and Somaliland have led to poor vegetation conditions and reduced farmland activities in the agricultural areas. There has been widespread crop moisture stress in most agro pastoral areas in southern regions, resulting in poor seed germination and crop wilting. Driest conditions were reported in Galgaduud, Middle Shabelle, Lower Shabelle, Bay, Bakool, Gedo, Middle Juba and Lower Juba regions. As a result, FSNAU reports indicate a likely below average Gu season harvest in July/August.
There is also a concern that there will be rapid deterioration of vegetation conditions in many parts of the country due to short lived Gu rains. With no rains expected until October 2021, moderate to severe drought conditions in Somalia cannot be ruled out during the mostly dry Hagaa (July to September) season.

Somalia Flood Update – 28 May 2021.pdf
With no rains in the last two weeks and minimal rains expected the month of June, the Gu rainy season came to an early end with a poor rainfall performance in many parts of the country despite heavy rains during the last week of April and first week of May. Comparing the Gu 2021 and the long term average for the season, Map 1 shows rainfall deficits in many areas of the country, with a significant deviation from the normal. While a few pockets of Somaliland and central areas shows a positive performance, there remains a great concern in the rest parts of the country and especially the southern regions. Further, according to the IGAD Climate Predication and Application Center (ICPAC), the Haggai season which is usually dry in many parts of the country is expected to be normal, safe for western parts of Somaliland that may record enhanced rains as seen in Map 2. With no more rains expected until the next rainy season, mild to moderate drought conditions are foreseen in the coming months. It should be noted that a large amount of rainfall in short periods of time is not effective in mitigating the drought conditions, as it underpins floods but it does not give enough time for water to infiltrate in the ground, recharging groundwater sources.
Shabelle River: Following a reduction of rainfall amounts in the Ethiopian highlands and within Somalia, compounded with the recession of the flood wave coming from Ethiopia, river levels along the Shabelle River inside Somalia have decreased drastically in the last 48 hours. The decreasing trend is expected to continue with minimal risk of flooding in Belet Weyne. However, a moderate risk of flooding will be sustained in the mid and lower reaches of the river until the end of the week. The situation could be further exacerbated by weak river embankments and open river banks, which is already causing floods in Jowhar.
Juba River: The river levels along the Juba continued to decrease over the last week. The levels are currently within normal with no risk of flooding given the rainfall forecast and decreasing trend of river levels.

Flood advisory for Juba Shabelle Rivers!
Observed levels of the Shabelle River in Somalia have continued to rise alarmingly in the past two weeks. This has been attributed to unprecedented excessive rains in the upper parts of the Ethiopian highlands especially in the last three days. The rainfall forecast for the coming week (08—14 May 2021) is pointing towards moderate to heavy rains within the upper parts of the Ethiopian highlands and light to moderate rains within the Shabelle basin inside Somalia.
Shabelle River: Heavy rains have been reported in Hiraan and Middle Shabelle regions in the last 24 hours with Jowhar station recording 86 mm of rainfall this morning. Flooding of high magnitude has been reported along the Shabelle River in Ethiopia and the flood wave is expected to reach the Somalia side in the next few days. There is a high flood risk in Belet Weyne district in the next to two to three days. The flood wave will be transmitted to the middle and lower reaches towards the end of the week. The situation could be further exacerbated by weak river embankments and open river banks, which is already causing floods in Jowhar. There is need for communities living along the riverine areas of the Shabelle River to take precaution as the river flow is expected to reach bank-full level before the end of the week.
Juba River: The levels have been low in the previous week but rose drastically in the last 24 hours. At Dollow, the levels have surpassed the moderate risk level of flooding. There is a moderate risk of flooding along the Juba River especially in Dollow district.

Somalia Flood Update – 10 May 2021.pdf
Observed levels continued to rise along the Juba and Shabelle Rivers both in Ethiopian and Somalia. However, there was a reduction of rainfall amounts in Somalia as well as in the Ethiopian highlands in the last 48 hours. The rainfall forecast for the period between 10—16 May 2021 is pointing towards moderate to heavy rains within the upper parts of the Ethiopian highlands and light to moderate rains within the Shabelle basin inside Somalia. Heavy rains are also foreseen in Galgaduud and Mudug regions between 10 and 11 May 2021 which may result to flush floods. Minimal rains are expected in Somaliland, Puntland and the southern parts of the country during the week.
Shabelle River: Flooding of high magnitude has been reported along the Shabelle River in Ethiopia and the flood wave is rapidly being transmitted to the side of Somalia with flooding being reported in parts of Hiraan region near the border with Ethiopia. Today, the river level at Belet Weyne reached the moderate flood risk level of 6.50 m. If this trend continues, the bank-full level maybe reached within seven to ten days in Belet Weyne leading to an overflow. The high risk flood level in Belet Weyne district will be sustained. The flood wave from Belet Weyne will be transmitted to the middle and lower reaches towards the end of the week and therefore there is a moderate risk of flooding in these areas during this week. The situation could be further exacerbated by weak river embankments and open river banks, which is already causing floods in Jowhar. There is need for communities living along the entire riverine areas of the Shabelle River to take precaution.
Juba River: Similarly, the river levels along the Juba continued to rise drastically over the last two days. At Dollow, the levels have surpassed the moderate risk level of flooding while at Luuq, the level is at 5.20 m which is 0.30 m below the moderate flood risk level. Given the rainfall forecast in the Ethiopian highlands, and the high river levels, there is a high risk of flooding in Dollow, Luuq and Bardheere during this week.

Somalia Flood Update – 13 May 2021.pdf
The coastal areas of Nugaal, Mudug and Galgaduud regions experienced heavy rains in the last 48 hours leading to flash floods in some areas. The Juba and Shabelle basins saw a significant reduction of rainfall amounts within the same period. However, observed levels continued to rise along the Juba and Shabelle Rivers both in Somalia following heavy rains in Ethiopia in the previous weeks. The rainfall forecast for the period between 12—18 May 2021 is pointing towards light to moderate rains within the upper parts of the Ethiopian highlands and light rains in most parts of Somalia with exception of a few pockets in Mudug that may record moderate rains during the forecast period.
Shabelle River: The flood wave from the Ethiopian highlands along the Shabelle River continued to stream into Somalia leading to gradual increase of river levels. The level in Belet Weyne today is 6.60 m which is beyond the moderate flood risk level. The reduced amounts of rainfall in the highlands has subsequently led to a slower rate of flow into Belet Weyne. However, there still remains a high risk level of flooding in Belet Weyne district as the water continue to stream in. The flood wave from Belet Weyne will be transmitted to the middle and lower reaches towards the end of the week and therefore there is a moderate risk of flooding in these areas during this week. The situation could be further exacerbated by weak river embankments and open river banks, which is already causing floods in Jowhar.
Juba River: The river levels along the Juba fluctuated in the last two days with a slight reduction in Dollow and Luuq stations and an increase in the mid reaches of Bardheere and Bualle. Given the rainfall forecast in the Ethiopian highlands, and the reducing river levels in upper parts of the river, the high risk of flooding changes to moderate level in the mid and lower parts of the river.
