At least 102 local government areas (LGAs) in Nigeria are highly probable to be flooded in 2020.
The local government areas are spread across 28 states in Nigeria, according to data from the Nigeria Hydrological Services Agency (NIHSA)’s 2020 Annual Flood Outlook (AFO).
All states and the Federal Capital Territory (FCT) are expected to experience different levels of flooding during the year, the agency stated.
Out of the 774 local government areas in Nigeria, 102 are predicted to be highly probable while 275 local government areas are probable to experience flooding.
Also, 397 LGAs are predicted to be less probable to flood occurrence and
NIHSA advised that people pay attention to all predictions and adhere to advice on how to respond to the situation.
The flood scenarios presented in the AFO are derived from the application of Geospatial Stream Flow Model (GeoSFM) and Soil and Water Assessment Tool (SWAT).
