The 2020 Gu rainy season was generally good with many areas in Somalia recording normal to above normal rains (Map 1 & 2 and Annex I). There was an early start of the season in late March in some areas and continued to spread spatially with a peak during the last two weeks of April. The season came to an early end during the second half of May. The good rains were beneficial to most water dependent sectors which saw a boost in the growth of pasture and crops in many areas and especially in the north eastern and central parts of the country which had a poor rainfall performance in the previous season. The rains also contributed to significant ground water recharge which had been depleted previously. There was also an improvement in animal body conditions thus more reproduction and availability of milk and meat. On the other hand, the heavy rains experienced in April led to both flash and riverine flooding affecting about 919 0001 people of whom 411, 905 were displaced and 24 killed. Further, along the Juba and Shabelle basins, more than 100,000 km2 of land was inundated as seen in Annex II. Belet Weyne town in Hiraan region was the worst affected by the floods and remained submerged for over two weeks. It is also worth noting that while the overall rainfall amounts for the season are mostly average to above average, there was a prolonged dry period since mid-May that is adversely impacting crop harvest prospects.

Observed river levels of the Shabelle River in Somalia have been rising for the past two weeks. This has been attributed to heavy rains in the upper parts of the Ethiopian highlands and localized rains in Lower Shabelle. The current Shabelle river levels at the upper reaches in Somalia are slightly above the historical normal range, while the lower reaches are at bank full levels. This has resulted in over bank spillage leading to riverine floods in parts of Jowhar, Balcad, Genaale and Afgooye. About 24,000Ha land is currently inundated along the Shabelle affecting over 150 villages. The rainfall forecast for the coming week (24—30 July 2020) is pointing towards moderate to heavy rains within the upper parts of the Ethiopian highlands and within Lower Shabelle inside Somalia. Observed river levels along the Shabelle River are expected to continue rising further in the coming week following the foreseen rains. Flooding in the middle and lower reaches of the Shabelle will be sustained in the coming week given the current situation and the foreseen rains. Areas to watch include Jowhar town and its environs; where the river level is near full crest and other riverine towns in the Lower Shabelle region. The situation could be further exacerbated by weak river embankments and open river banks. Along the Juba river levels are within normal for this period of the year.

There was further reduction of rainfall during the week ending on 31 May 2020 as we approach the end of the Gu rainy season which usually ends in late May in some places and early June in others. A few pockets in the southern and northeastern regions however recorded light to moderate rains. In Somaliland, a heavy storm on 29 May led to flash floods in Hargeisa causing three human deaths and destruction of properties. The rainfall forecast for the week ending on 07 June 2020 is calling for rainfall amounts less than 50 mm cumulatively in coastal parts of Lower Juba and Lower Shabelle regions. A few pockets of Bari, Sanaag and Sool will receive some light to moderate rains until the end of the week. Moderate rains are also expected in the Juba and Shabelle headwaters in Ethiopia during the forecast week. The rest of the country will remain dry. With the significant reduction of rains and subsequent decrease of river levels along the two rivers, there is no is foreseen risk of flooding this week and the coming one. Shabelle River: River levels at Belet Weyne, which remained at bank-full for 17 days since 12 May 2020, started to drop on 29 May 2020. Today, the river level is at 5.50m. The flood situation in the district improved greatly during the week with most water having drawn back to the river and residents who had earlier evacuated to higher grounds started to go back to their homes. However, some areas are still water logged with standing water posing a threat of waterborne diseases. In Bulo Burti the river remained high over the past week, with a section of the Indha Ceel village affected by floods. The river level at Jowhar slightly decreased and today it is at 5.05m, which is 0.50m below the high flood risk level. River levels have also started to decrease in the lower reaches and this trend is expected to continue before stabilizing in the coming week. No risk of flooding is foreseen this week. Juba River: There has been a drastic reduction of river levels along the entire channel. Flooding that was recently reported has reduced in middle and lower reaches. The river level at Bardheere today is at 5.32m which is about 3.0m below the high risk flood level. With no foreseen rains, the river levels will continue to drop this week and stabilize in the coming week. No risk of flooding is foreseen along the entire channel of Juba. In Bay and Bakool regions: Little to no rains were recorded during the week. The forecast for this week indicates reduced rainfall prospects in these regions with no flood risk anticipated. Somaliland, Puntland, and Central regions: One day of heavy storm that lasted less than an hour was observed in Somaliland leading to flash floods. In Puntland, there were light to moderate rains between 26 and 30 May in a few areas. The forecast for the coming week indicates light to moderate rains in few places of Bari, Sanaag and Sool regions. The rest of the area will remain dry.

The current Gu (April-June 2020) season rains continued with moderate to high intensity in many places across Somalia during the week that ended on 10 May 2020. The eastern Ethiopian highlands, which are responsible for most of the river flow along the Juba and Shabelle Rivers, also recorded significant amounts of rainfall during the same period. Heavy rains led to flash floods in northern regions and riverine flooding along the Juba and Shabelle Rivers in the south. The rainfall forecast for the week ending on 17 May 2020 shows a significant reduction of rains across Somalia, with rainfall confined mostly to southern and coastal parts of southern Somalia. However, along the Juba and Shabelle rivers high to moderate flood risk is likely to persist in the next two weeks because of incoming river flow from the upper catchments. The high Shabelle and Juba river levels are expected to continue to threaten urban and riverine populations along the two rivers. Shabelle River: River levels continued to rise following heavy rains within the Shabelle River basin in both Ethiopia and inside Somalia. Mataban, Belet Weyne, Bulo Burti, Jowhar and Balcad rainfall stations recorded over 50mm in the last week. Today, 11 May, the river level at Belet Weyne is 8.10m, which is already above the High flood-risk threshold and just 0.20m less than the bank-full level of 8.30m. Parts of Belet Weyne riverine areas have been experiencing flooding since the end of last week, where many HH’s have since evacuated. The river level at Jowhar continued to rise slowly reaching 5.3m as of today, which is above the high flood-risk threshold and only 0.2m below the 5.5 m bank-full level. Flooding is currently reported also in Jalaalaqsi. Localized flooding continued in Tugaarey village within Jowhar district inundating over 500 hectares of farmland and displacing over 400 households. A similar trend has been observed in Balcad and the lower reaches of the river where flooding was reported in Kurtunwaarey. The levels are expected to continue rising along the entire channel of Shabelle as more waters from the eastern Ethiopian highlands are still streaming in. High risk of flooding is foreseen along the Shabelle during this week; and Moderate Risk the following week. It is advisable that riverine communities within low-lying areas of Belet Weyne who have not evacuated yet to do so, while following guidelines by the local authorities. Existence of river breakages (50 points identified and reported by SWALIM in February 2020) along the Shabelle is likely to exacerbate the flooding unless urgent measures are taken in river management. Juba River: River levels increased significantly in the last three days at Dollow, Luuq and Bardheere monitoring stations, all within Gedo region. Flooding has been reported for two days and expected to continue in the week due to the high flows being transmitted from Ethiopian and Kenyan sides. Using high-resolution satellite images, SWALIM identified more than 50 Km2 of flood-affected areas along the Juba since 23 April 2020 and has continued to increase to date. Affected areas include Dollow, Belet Hawa, Luq, Saakow, Buaale, Jilib and Jamame districts. Given the current high levels and rainfall forecast, there is a High risk of flooding along the entire Juba river channel this week; and Moderate Risk the following week. In Bay and Bakool regions: Moderate to heavy rains were recorded in Bay and Bakool regions over the last week. The forecast for this week indicates reduced rainfall prospects in these regions with no flood risk anticipated. Somaliland, Puntland, and Central regions: Since the beginning of the current rainy season in April, moderate to heavy rains have been reported in many parts of the northern and central regions. However, there was a reduction of rainfall in Somaliland while moderate to high precipitation were reported in parts of Puntland. Heavy storms in Baran (Sanaag region) on 06 and 07 May 2020 led to severe flash floods and destruction of properties and cropland. This week will see a reduction of rainfall amounts in both northern and central regions with no risk of flash floods expected.

The week that ended on 03 May saw increased rainfall in most regions in Somalia. Heavy rains led to flash floods in northern regions and riverine flooding along the Juba River in the south. The significant rains received so far, follows another above average rainy season, observed during the Deyr (October-December) 2019 season. There has been a general improvement in pasture and ground water recharge across the country. The rainfall forecast for this week is for more rains, especially in the Juba and Shabelle river basins, while there will be a slight reduction of rains in the northern regions. Moderate to high flood risk is likely to persist at least through mid-May, threatening urban and riverine populations, including in Belet Weyne (Hiran) and Jowhar (Middle Shabelle). Shabelle River: River levels continued to rise following heavy rains within the Shabelle River basin in both Ethiopia and inside Somalia. Mataban, Belet Weyne, Bulo Burti, Jowhar and Balcad rainfall stations recorded over 50mm in the last week. Today, the river level at Belet Weyne is 7.20m, which is just 0.10m less the high risk flood level and 1.10m less the bank-full level. The river level at Bulo Burti continued to rise slowly reaching 4.55m today. In Jowhar, the river level reached 5.30 m, which is the high-risk flood level and has remained so in the last four days. Localized flooding has been reported in Tugaarey village within Jowhar district. A similar trend has been observed in Balcad and the lower reaches of the river. The levels are expected to continue rising along the entire channel of Shabelle as more waters from the Ethiopian highlands are still streaming in. High risk of flooding is foreseen along the Shabelle during this week and the following week. Further, reports from the Ethiopian catchment indicate high river levels and flooding in some locations. There is therefore a high likelihood that these waters will reach in Belet Weyne in two to 5 days, which will likely exceed bank full level in the area. It is advisable that the riverine communities within Belet Weyne to prepare for possible evacuation in the course of the week. Existence of river breakages (50 points identified and reported by SWALIM in February 2020) along the Shabelle is likely to exacerbate the flooding situation unless urgent measures are taken. Juba River: River levels were very high at the beginning of last week and started to drop slightly in the last three days in Dollow, Luuq and Bardheere monitoring stations, all within Gedo region. Flood waters started to recede back to the river in Bardheere and this has in turn led to an increase of levels in the downstream reaches where flooding continue to be observed. Using high-resolution satellite images, SWALIM identified 51 Km2 of flood-affected areas along the Juba for the period 23 to 30 April 2020. The worst affected areas are found in Saakow, Buaale, Jilib and Jamame districts. Given the current high levels and rainfall forecast, there is a High risk of flooding along the entire Juba river channel. In Bay and Bakool regions: Heavy rains resulted to flash floods in some areas within Bay and Bakool regions. In the last week of April, Baidoa station recorded 190mm while Dinsor recorded 110mm of rainfall. In Bakool region, 88 mm and 178 mm of rainfall were recorded in Hudur and El Berde stations respectively in the same period. Flash floods were observed in Qansadheere, Dinsor districts where around 124 Ha of crop fields comprising of Sorghum, Maize, Beans and Sesame were affected. Moderate risk of flooding remains in this area. Puntland, Somaliland and Central regions: Since the beginning of the rainy season, moderate to heavy rains have been reported in many parts of the northern regions. Heavy storms in Qardho, Bari region and Burao in Togdheer region on the night of 27 April 2020 led to severe flash floods leading to massive destruction of properties and loss of lives. In Puntland, more than 10 stations in Bari, Nuugal and Mudug regions recorded heavy rains of between 50 mm to 100 mm cumulatively in the last seven days. Moderate rains have also been observed in Somaliland. This week will see a reduction of rainfall amounts in both areas with no risk of flash floods.

The Gu (April-June) season to date has seen significant rainfall across Somalia with many areas recording more than twice their average rainfall over the period. The rains which intensified since mid-April have been well distributed in terms of space and time. The heavy rains have left many areas water logged for weeks. In particular, the Juba and Shabelle basins have had excessive flows that will keep flood risks high during this week and at moderate risk in the coming week. On the down side still, the wet conditions and ample vegetation have created favorable conditions for the spread of desert locust infestation across Somalia. On the up side of the rains, there has been tremendous improvement of vegetation conditions and overall water availability throughout Somalia. In most parts of Somalia, Gu season rainfall usually start to decline starting in mid to late May. The rainfall forecast for the week ending on 24 May 2020 shows a significant reduction of rains across Somalia, with rainfall of up to 50 mm cumulatively confined mostly to coastal parts of Lower Juba and Lower Shabelle regions. The Juba and Shabelle rivers’ high to moderate flood risk is likely to persist during this week due to continuing high flows from the upper catchments. Shabelle River: There was a reduction of rainfall amounts in the basin during the last week. River levels at Belet Weyne have remained at bank-full since 12 May 2020 to date, leading to extensive flooding of the flood plain riverine areas. More than 230 km2 have been flooded including 11 km2 of urban land and 225 km2 of agricultural land. The levels are expected to start going down at Belet Weyne in the next 2 – 3 days. The river level at Jowhar decreased slightly and is at 5.20 m today. River levels are expected to remain high in the lower reaches of the river as the lagged flood flows stream in from upstream reaches and rivers flow bank full through to Qoryoley. High risk of flooding is foreseen along the Shabelle during this week; and Moderate Risk the following week. Existence of river breakages (50 points identified and reported by SWALIM in February 2020) along the Shabelle will exacerbate the flooding unless emergency repair measures are taken. Juba River: River levels increased significantly beginning of last week at Dollow, Luuq and Bardheere gauging stations, all within Gedo region. Flooding that was reported has reduced although some farm lands are still under water in Dollow and Luuq districts. The river level at Bardheere has remained at 9.00m for the last seven days, but is expected to start going down in the next 2-3 days. Using VHR satellite imagery, SWALIM identified more than 10 km2 of flood-affected areas in Gedo region and approximately 140 km2 of inundated land in Middle and Lower Juba regions. Currently, affected areas include Dollow, Luuq, Saakow, Buaale, Jilib and Jamame districts. Given the current high levels in Bardheere, a High risk of flooding along the entire Juba river channel remains in place this week; with a reduction to Moderate Risk the following week. In Bay and Bakool regions: Little to no rains were recorded during the week. The forecast for this week indicates reduced rainfall prospects in these regions with no flood risk anticipated. Somaliland, Puntland, and Central regions: No rains were reported in the northern regions during the last week. This week will see a reduction of rainfall amounts in both northern and central regions with no risk of flash floods expected.

The ongoing Gu seasonal rains in the country have led to disruption of road networks in some areas which have experienced flash floods and riverine flooding. The most recent affected area was Badhan district in Sanaag region that received heavy rains on 05 and 06 May leading to flash floods that left tens of households displaced. Unconfirmed acreage of cropland has also been destroyed. Flash floods were also reported in the wadis of Bay and Bakool regions which have been experiencing heavy rains since the beginning of the season. The rainfall forecast for the coming week is for increased rainfall in the southern regions as well as the Ethiopian highlands. In the next three days, moderate to heavy rains are expected in these regions. This is likely to lead to flash floods especially in Bay, Bakool and Lower Juba where the rains will be intensified. A reduction of rainfall amounts is expected in the northern regions which will record light to moderate rains during the week. The river levels in Gedo, along the Juba reduced slightly in the last three days while an increasing trend was observed in Middle Juba and Lower Juba. Flooding is expected to continue during the week along the lower reaches of the river. The River levels along the Shabelle River at Belet Weyne today is at 7.74m which about half a meter away from the bank full level (8.30m). Since last night flooding has been reported in parts of the district specifically in two sections of Hawo Tako settlement (Dhagax Jebis and Shaah Macaan) where residents have began evacuating. In Jowhar, the river level has remained at the high flood risk level of 5.30m for the last one week. Given the forecast and existing high river levels, flooding alert remains in place for Belet Weyne until further notice.

This week has seen a significant reduction of rainfall amounts in Somalia save for a few places in the southern coastal areas. This trend is normal as rains start to reduce in the second half of May in many areas while the coastal areas continue to record rainfall through June and July. In general, the seasonal rains have been considerably good across the country with some areas still experiencing the negative effects of the rains including Middle Juba, Lower Juba and Hiraan regions.

The week ending on 24 May 2020 saw a significant reduction of rainfall amounts across the country. A few pockets in the southern and northeastern regions however recorded light rains. In general, the seasonal rain performance was remarkable and beneficial to all the water dependent sectors. The heavy rains within Somalia and the Ethiopian highlands since the start of the season resulted into excessive flows and flooding along the Juba and Shabelle basins. Analysis using very high-resolution (VHR) satellite images of flood extent along the Juba and Shabelle basins shows that the Gu 2020 flood extent along the Shabelle river is less as compared to the one detected during Gu 2018 and Deyr 2019. Along Juba River, the Gu 2020 flood is larger than the one detected during Gu 2018 but less than the one of Deyr 2019. According to UNOCHA, 836,128 people have been affected during this season within the Juba and Shabelle Rivers which is a larger number compared to that of 2018 and 2019. Further analysis of river flow at Belet Weyne shows that for the third year in a row a flood extent that would normally have a recurrence of 50 years has been surpassed. The rainfall forecast for the week ending on 31 May 2020 is calling for rainfall amounts of up to 50 mm cumulatively in coastal parts of Lower Juba and Lower Shabelle regions. Bari, Nugal, Sanaag and parts of Sool will also receive some light to moderate rains until the end of the week. Moderate rains are also expected in the Juba and Shabelle headwaters in Ethiopia during the forecast week. A moderate flood risk along the two rivers is likely to persist during this week due to continuing high flows from the upper catchments. The situation is expected to improve in the following week with water logging abating due to high daily evaporation. Shabelle River: There was a reduction of rainfall amounts in the basin during the last week. River levels at Belet Weyne have remained at bank-full since 12 May 2020 to date. Flood waters that had inundated the town started to draw back to the river in the last two days and the situation will to improve in the coming days. The river level at Jowhar decreased slightly and today it is at 5.10 m. Using VHR satellite imagery, SWALIM identified a total of 445 km2 of flood-affected areas in the basin during this flood season. River levels will start to decrease towards the end of this week in the lower reaches of the river as the lagged flood flows stream in from upstream reaches. Moderate Risk of flooding is foreseen along the Shabelle during this week; and No flood risk the following week. Juba River: There has been a drastic reduction of river levels along the entire channel. Flooding that was recently reported has reduced in the upper reaches but some farm lands are still under water in Middle and Lower reaches. The river level at Bardheere today is at 6.18 m, which a 3.0 m drop from the last four days. Using VHR satellite imagery, SWALIM identified a total of 564 km2 of flood-affected areas along the Juba River during this flood season. Given the current situation, a Moderate Risk of flooding along the lower reaches remains in place this week; with a reduction to No flood risk the following week. In Bay and Bakool regions: Little to no rains were recorded during the week. The forecast for this week indicates reduced rainfall prospects in these regions with no flood risk anticipated. Somaliland, Puntland, and Central regions: No rains were reported in Somaliland while light rains were reported in Puntland on 25 May 2020.

The Gu rainy season continued to spread in time and space within Somalia. Moderate to heavy rains were reported in many places in the last two days since the last update. Gedo, Bay, Bakool and Middle Juba regions in the south recorded the highest amounts of rainfall. Heavy rains were also observed in Somaliland where some stations received a total of more than 100mm in a single day on 21 April 2020. The rainfall forecast for the coming week is calling for increased rainfall activities in most areas inside Somalia and in the Ethiopian highlands. The rains will be between today and tomorrow followed by a slight reduction of the activities thereafter. There has been very heavy rains within the Juba basin over the last 24 hours. Flash floods have been reported in Dollow this morning while the river level at Luuq is 0.50m away from the moderate flood risk level. The levels in Bardheere have surpassed the moderate flood risk level and flooding has been reported in the area. In Middle Juba region, the levels are also very high and expected to continue rising. There is therefore a High risk of flooding along the Juba River during this week. The River levels along the Shabelle River remain below normal at this time of the year. Given the rainfall forecast within the Ethiopian highlands, the levels are expected o continue rising with no foreseen immediate threat of flooding. There is also a High risk of flash floods in Bay region due to foreseen heavy rains within the next 24 hours.
