September, 2nd assessment and 3rd outlook, 2025

Bulletin

Moderate to high surface water flows are forecast for most Kiremt moisture-benefiting catchments during the period of September 21-30, 2025, which is expected to significantly enhance surface and groundwater recharge while increasing water levels in ponds and reservoirs. However, due to significant rainfall in the previous dekade that has saturated the ground, there is a high probability of flash floods and elevated river flows, particularly in flood-prone basins, with riverine flooding and inundation presenting a particularly high risk in the lower reaches of the Tekeze, Lower Omo Gibe, Lower Abay, and Lower Awash catchments. Consequently, communities residing along river banks, in wetlands, and swamplands are advised to exercise heightened caution.
