Tropical Storm Update - Issued: 24 November 2020

Tropical Storm GATI weakened leaving a trail of destruction in parts of Bari and Sanaag regions The tropical storm GATI has weakened further and is moving westwards with a speed of 7KPH. It is expected to dissipate in the next 12 hours. The storm left behind a significant physical and economic damage especially in Bari region. More than 700 houses were destroyed, several boats and fishing gears damaged and loss of a large number of livestock. This has led to loss of livelihood for most families and may take time and huge financial input to replace the loss. There was a reduction of rainfall amounts and wind speeds in the last 24 hours in many areas along the storm path. This trend is expected to continue as the storm gets weaker and the situation will stabilize thereafter. The sea conditions are still rough over the coastal areas of Puntland and Somaliland and fishermen are advised not to venture into fishing operations for today. The storm impacts will continue to be experienced today in Sanaag and Woqooyi Galbeed coastal areas but with lesser magnitude compared to what was experienced Bari in the last two days. The rainfall forecast for Somaliland and Puntland is calling for moderate rains in the next couple of days and a reduction towards the end of the week. The Ethiopian highland and southern parts of the country are also expected to experience moderate to heavy rains in the course of the week. Given the three days rainfall forecast, flash floods may occur in Toghdheer, Sool, Galgaduud and Mudug regions within the areas neighboring Ethiopia.

Somalia Rainfall Forecast - Issued: 29 October 2020

Many places received light to moderate rains across Somalia in the last two days as the Deyr rainy season continued to spread albeit with a delay in some areas. Hiraan, Bakool and Bay regions in the south recorded heavy rains of up to 60mm within 24 hours. Light to moderate rains were observed in the Ethiopian highlands during the same period. River levels are within normal in Belet Weyne and Bulo Burti districts while the mid and lower reaches are still at high levels. Today’s River level at Belet Weyne is 5.00m while Jowhar is 5.25m which is almost at bank-ful. In Agfooye, the levels are at full capacity and most parts of the riverine areas remain inundated. A recent ground survey by SWALIM indicates that there are several open and weak river embankments in Jowhar, Balcad and Afgooye districts with some ranging from 500m to 1,000m wide. Some villages continue to be under water since August 2020. River levels along the Juba increased slightly during the last few days due to moderate rains in the Ethiopian highlands. The cumulative rainfall forecast for this week indicates moderate to heavy rains in many areas across the country. In the western parts of Somaliland and south of Bari region in Puntland the rains will be less. The Ethiopian highlands whose soil moisture is already saturated due to heavy rains since July 2020 will see an increase of rainfall amounts this week. This will subsequently lead to a further increase in river levels especially along the Shabelle river. Given the rainfall forecast and current situation along the two rivers, High Risk of flooding remains along the lower reaches of Shabelle while along the Juba River there is Moderate Risk of flooding foreseen . There is a also a High Risk of flash floods in the built up low lying areas especially in Galgaduud, Mudug, Bay and Bakool regions

Flood Update for River Shabelle - Issued: 03 September 2020

Moderate to heavy rains persisted in the upper parts of the Shabelle Basin within the Ethiopian highlands during the last week. Consequently, observed river levels of the Shabelle River in Somalia continued to rise. Today, the river level at Belet Weyne is 8.00m which only 0.30m away from bank-full level. Overbank spillage within Belet Weyne town could happen any time from now given the high river levels. Currently, Hawa-Hako and Hilaac sections of the district are flooded since mid August and unconfirmed number of people were displaced. Massive flooding has been reported 20km north of Belet Weyne town in the last 24 hours due to overbank spillage. A similar trend of exceptionally above normal river levels is being observed in Bulo Burti, Jalalaqsi, Mahadey weyne, Jowhar, Balcad and Afgooye districts with floods being reported in several points due to overbank flow and lateral flows from broken river banks. The flooding situation has been exacerbated by weak river embankments and open river banks. As of today, an estimated 132,000 ha of agricultural land and 294 villages along the Shabelle River have been affected by the Hagaa floods. The rainfall forecast for the coming week (03—10 September 2020) is pointing towards moderate to heavy rains within the upper parts of the Ethiopian highlands. Observed river levels along the Shabelle River are expected to continue rising further in the coming week following the foreseen rains. High risk of flooding is foreseen in Belet Weyne district. 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. Recent analysis by SWALIM indicates that there are 109 open river bank points along the Shabelle River.

Somalia Rainfall Forecast - Issued: 28 September 2020

Light to moderate rains continued to spread in the northern parts of Somalia over the past one week; while many areas in the south remained dry over the same period. At the Ethiopian highlands, where majority of the flow along Juba and Shabelle Rivers originate from, moderate to heavy rains continued to be experienced over the last one week. River levels along the Shabelle reduced slightly in the upper reaches, but remain above the high flood risk levels at Belet Weyne and Bulo Burti. In Jowhar the river level has risen from last week’s levels, and today it is at 5.20m, which is only 5cm below the high flood risk level. The cumulative rainfall forecast for this week indicates light to moderate rains spread across the northern parts of the country. Parts of Bari, Nugaal, Sool and Sanaag Regions, are expected to receive high rainfall in the forecast period, which may lead to flash floods. The central parts of the country are expected to receive light to moderate rains, while most of the southern parts of the country will remain either dry or receive little rains in the coming week. Within the Ethiopian highlands the forecast indicates moderate to heavy rains within the forecast period. This may lead to an increase of river levels along the Shabelle river thus increasing the risk of flooding especially in Hiraan and Middle Shabelle Regions. Given the rainfall forecast and current situation along the two rivers, High Risk of flooding remains along the Shabelle while there is no risk of flooding foreseen along the Juba River.

Status of River Breakages Along Juba and Shabelle Rivers - Issued September 2020

Following three consecutive significant rainy seasons, (Dery 2019, Gu 2020 and Hagaa 2020-traditionally dry) river levels along the Juba and Shabelle Rivers have remained high for a long period with flooding due to overbank spillage and existing river breakages/weak embankments. The high rains and subsequent floods of Gu 2020 saw new open river banks. SWALIM has updated the status of the river breakages along the Juba and Shabelle Rivers using available Very High Resolution (VHR) satellite imagery and a Digital Elevation Model (DEM); supported by “limited ground truthing” field observations, where feasible. Four types of breakages have been identified, namely; open, overflow, potential overflows and closed with sandbags. The open breakages are those that are currently open as observed on the latest VHR image available. The open breakages are further categorised into four classes in a chronological order, according to the assessment date and/or their former status as seen in the maps. All the observations reported refers to the latest suitable VHR satellite image available, which is indicated in the online database. 154 Open points have been identified, 109 on the Shabelle River and 45 on the Juba River which require immediate action. It is noted that several new breakages occurred during the Gu 2020 season which was exceptionally good along the two rivers. Belet Weyne district was worst affected along the Shabelle while Bu’aale district was worst affected along the Juba. SWALIM has also embarked on a ground truthing survey along the Shabelle River in Jowhar, Balcad and Afgooye districts. The survey aims to monitor existing open and weak riverbanks while capturing the dimensions of each point. The findings of the survey will be key to planning and interventions on those points. SWALIM is pleased to share with you maps and tables of the status of river breakages along the two rivers in the links below. This information is also available on the SWALIM website. Users are advised that the methodology is biased towards Remote Sensing (RS) interpretation with only limited “ground truthing” due to access constraints. Open breakages might have been omitted in some cases where satellite images may not have been very clear (e.g. heavy cloud cover) or were not available.
