The Oyo State Government has issued a public warning over the likelihood of flash floods, temporary road overflows, and rising temperatures as the 2026 rainy season begins across the state.
The Commissioner for Environment and Natural Resources, Ademola Aderinto, said residents should take precautionary measures as heavy rainfall and thunderstorms are expected in the coming weeks.
In a statement released in Ibadan on Saturday, the commissioner explained that the early rains could trigger sudden flooding in several communities because the soil remains relatively hard after the dry season, reducing water absorption and increasing surface runoff.
“The soil across the state is still relatively firm, limiting water infiltration and causing heavy surface runoff on roads, drainages, and some communities,” Aderinto said.
He noted that while most flooding incidents were expected to be temporary, blocked drainage systems and illegal environmental activities could worsen the situation and lead to more destructive flooding.
The state government specifically warned against indiscriminate waste disposal, obstruction of drainage channels, and illegal dredging activities capable of disrupting the natural flow of water.
According to the government, prolonged flooding on roads could damage public infrastructure, increase the risk of accidents, and affect critical facilities across the state.
Authorities said environmental monitoring and drainage management efforts were ongoing to minimize the impact of the seasonal rains.
Beyond flooding concerns, the government also warned residents to prepare for intermittent heatwaves during the transition into the peak rainy season.
Temperatures are expected to rise between 33 and 35 degrees Celsius in some parts of the state, creating additional health risks, particularly for vulnerable residents.
Officials advised residents to remain hydrated, avoid prolonged exposure to direct sunlight, and stay in cool or shaded environments during periods of intense heat.
The advisory comes as several Nigerian states begin preparing for seasonal weather-related emergencies following earlier forecasts by national meteorological and hydrological agencies warning of increased rainfall and possible flooding in parts of the country this year.
