23 Apr, 2020 Alerts and Early Warning 26

Flood Alert: Shebele River 

Communities along the Shebele River in Mustahil (Ethiopia) and Beletwein (Somalia) and downstream towns are advised to take precautions due to the high level of flood risk in the coming two weeks. 

  • Using the forecasted rainfall in the upper catchment, the river water level is expected to rise sharply in the next one week. The total forecasted mean rainfall in the upstream of Beletwein (Somalia) for the next five to 10 days is between 50 and 130 mm. 
  • The Shebele River is a transboundary river between Ethiopia and Somalia and periodically floods in the downstream stretches. In the last two years floods occurred in April-May 2018 and November 2019. ICPAC carried out streamflow modelling and forecasting in the Shebele river, however because there is no reliable and available data to calibrate and validate the model, historical floods occurrences are used as guide.
