The Greater Horn of Africa Climate Outlook Forum (GHACOF) has confirmed a reduction of the chances of experiencing a La Nina event during the March to May rainy season. During the recent GHACOF, the March to May 2018 rainfall forecast for the region was released. According to the forecast, Gu 2018 season in Somalia is expected to be normal (40% probability of normal rains) with a tendency of 35 % probability of below normal rains in most parts of the country. This also includes part of the Ethiopian highlands which contribute significantly to both Juba and Shabelle river flow inside Somalia and all inland parts of the country. Further, Awdal , northern parts of Sanaag and Bari regions in the north as well as the southern coastal regions of Lower Juba and Lower Shabelle are expected to experience normal rains (40% probability of normal rains) with a tendency of 35% above normal rains as seen in Figure 1.
The expected depressed rains in many parts of the country will only exacerbate the existing drought conditions. Togdheer, Sool , Nugal and Mudug regions will be worst affected owing to the prevailing drought conditions. Gedo, Bakool, Hiraan and parts of Bay will also be affected adversely by the below normal rains.
This outlook is a consensus forecast designed for a regional audience that addresses the rainfall totals summed over the three-month period from March to May 2018. However, SWALIM and other technical partners will keep updating this forecast for shorter lead time periods and will share with you through the regular bulletins throughout the rainfall season.
