Somalia Flood Update – 25 May 2021.pdf

Flood Alert
Title Language: 
During the last two weeks there has been minimal or no rains in most parts of Somalia, marking an early cessation of the Gu 2021 rains which also had a late onset. The rainfall forecast for the next week till end of May, shows no rains in the country. Further, no rains are expected in the month of June according to most forecast models. With a late start, short growing period and an early end of the season, drought conditions which were detected in February, may continue to impact some areas especially in the southern regions where the total rainfall recorded so far is less than the long term average. There is also a great concern in the northern regions which recorded good rains in a period of two weeks before the cessation. SWALIM will carry out an in-depth analysis of the situation in the coming days. Shabelle River: Following a reduction of rainfall amounts in the Ethiopian highlands, there was a subsequent decrease in runoff from the upper reaches of the basin to Somalia. However, flood waters from previous two weeks rainfall are still streaming into Somalia side of the basin. Today, the level in Belet Weyne is 8.25 m and is likely to reach the bank-full level any time from now, with a high risk of flooding in the town. During the last week, a few villages in the upstream parts of Belet Weyne town were affected by flooding with evacuation having taken place. The flood wave from Belet Weyne will be transmitted to the middle and lower reaches in the course 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 continued to decrease over the last week. The levels are currently slightly above normal and expected to stabilize as the week progresses. Given the rainfall forecast and decreasing trend of river levels there is no risk of flooding along Juba in the coming week.
