September 3rd assessment and October 1st outlook ,2025

Bulletin

In the coming first dekade of October, moderate to high surface water flows are expected to enhance surface and groundwater recharge, raising water levels in ponds and reservoirs; however, due to significant rainfall in the previous dekade that has saturated soils, there is a high probability of flash floods and elevated river flows, particularly in flood-prone basins like the lower reaches of the Lower Omo Gibe as well as Abay catchments. Consequently, communities along riverbanks and in wetlands are strongly advised to exercise heightened caution, while relevant sectoral institutions are urged to implement the basin-specific hydro-meteorological recommendations .
