ICPAC added that less than usual rainfall expected over a few regions in western South Sudan, central and south-eastern Ethiopia, central Somalia and western Uganda.
It further warned that there is a likelihood of flooding incidences over the flood prone areas in central-eastern Sudan, and northern and north-eastern parts of Ethiopia.

South Sudan flooding
An estimated 273,000 people have been affected by widespread flashfloods among whom over a hundred displaced in 12 counties in South Sudan as of September 2025, the UN humanitarian agency said.
According to UN Office for Coordination of Humanitarian Affairs (UN-OCHA), the affected populations are Jonglei, Unity, Upper Nile and Central Equatoria, with Jonglei and Unity states accounting for over 91 per cent of those impacted.
Over 104,000 people in the counties of Panyijiar, Twic East, Terekeka, Pochalla, Fangak and Ayod are displaced and sheltered on higher grounds, OCHA said.
The agency noted that a section of the dyke on the western side of Old Fangak in Jonglei State broke on August 30 due to increase of water level from the River Nile, submerging the entire town.
