The Lagos State Government has warned that the state will experience above-normal rainfall in 2025, with potential flash floods in some areas that could disrupt commercial activities, pose risks to lives and properties, and cause flight delays.
The Commissioner for Environment and Water Resources, Mr. Tokunbo Wahab, disclosed this on Wednesday during the Seasonal Climate Prediction (SCP) briefing held at Alausa, as contained in a statement on his official X (formerly Twitter) account on Monday.
According to Wahab, the Nigerian Meteorological Agency (NiMet) has forecasted an early onset of the rainy season, beginning in the last week of March, with the season expected to extend until early December.
Lagos is projected to receive an average annual rainfall of 1,936mm, exceeding the 1991-2020 long-term average.
“The Lagos State Government on Wednesday stated that the state is anticipated to experience above normal rainfall amounts in the first peak of the rainy season while normal rainfall amounts are expected in the second peak of the 2025 rainy season,” the statement read in part.
It added, “He said it is also expected that the high amounts of rainfall sometimes would lead to flash flooding events in some parts of the State adding that strong winds are expected during the onset and end of each rainy season and this may put lives and properties may be at risk, disrupt commercial activities and flight delays which could result to revenue loss.”
The commissioner further explained that the forecast is based on the neutral phase of the El Niño-Southern Oscillation (ENSO), which will persist for the first six to eight months of the year. This could result in prolonged rains, a delayed cessation period, and an increased risk of extreme weather events, including strong winds at the onset and end of the season.
