Epe is expected to have a rainfall onset date of April 2, cessation date of December 5 and an annual amount of 1952 mm.
According to him, below normal rainfall is anticipated in the first half of the rainy season, while normal to above normal rainfall is expected in the second half of the rainy season.
He said the Ministry’s collaboration with NiMet on Seasonal Climate Prediction had been valuable as a vital weather and early warning tool for farmers, decision makers, operators of the various sectors and businesses likely to be impacted by the annual rainfall.
He said government had plans to downscale the Seasonal Climate Prediction to stakeholders and emergency workers in the state.
He added that the state had deployed and maintained its network of weather stations and river gauge stations to monitor the weather and river levels in the state and increase the preparedness for weather and flood related issues.
“We want to assure you that our state will continue to reap the benefits of a careful and rigorous execution planning, as our flood control measures are stepped up to contain any imminent rainfall.
“The Ministry has embarked on an all-year-round drainage maintenance programme for effective and efficient flood control, in addition to an efficient and sustainable solid waste management system,” Wahab said.
He noted that to effectively contain flooding in the state, government was determined to maintain the synergy and partnership with the Ogun-Oshun River Basin Authority (OORBDA).
He added that the rainfall from neighbouring Ogun, Oyo and Osun states, dams release and river water levels into the state would also be monitored.
He said the partnership ensured control and monitoring of the steady and systemic release of water from Oyan Dam to prevent flooding as it reached the Ogun River.
He said the relationship had been highly beneficial and would be sustained.
He said proactively, the state had strengthened the Flood Early Warning Systems (FEWS) to deliver reliable, timely and effective flood information at an appropriate response time.
He added that the low-lying Agiliti, Agboyi, Itowolo and Ajegunle communities would be closely monitored with respect to the likelihood of Ogun River flooding as well as all other river basins in the state.
