The Lagos State government has urged residents to prepare for the rainy season as the state is expected to witness between 240 to 270 days of rainfall in 2020.
The state commissioner for Environment and Water Resource, Mr Tunji Bello revealed this at a news conference on the 2020 Seasonal Rainfall Predictions and Prevention of Flooding in Lagos, held at the Ministry’s Conference room on Tuesday.
According to him, it is necessary to inform Lagos residents about the 2020 rainfall prediction by the Nigerian Meteorological Agency (NIMET).
Mr. Bello, while giving reference to a report obtained from the Nigerian Meteorological services (NIMET), stated that the earliest predicted onset of the rainy season is 17th March with other areas following.
He added that the rainy season is expected to cease earliest by 22 Nov in Surulere with other areas following after.
“Ikeja is expected to have about 1526mm, while that of Badagry is 1750mm, Lagos Island with 1714mm, Ikorodu with 1690mm and Epe with 1730mm of rainfall.
“Lagos Island was expected to have a rainfall onset date of 19th March with an error margin of three days, while its cessation date is expected to be 26th of November,” he stated.
Mr Bello explained that residents staying in coastal areas will witness flash-floods which he describes as ‘natural’, but it will disappear in a matter of time if the drains are clean.
“As long as the drains are clean, we should be assured that, in a matter of time, the flash flood will disappear.
“It must be noted that anytime the Lagoon level rises, it may “lock-up” the discharge points drainage channels and until it recedes, there will be no discharge. Occurrences like these also cause backflows, resulting in flooding”, he emphasised.
He disclosed, “The Lagos State Government has established synergy and partnership with Ogun-Osun River Basin Authority and this has ensured control and monitoring of the steady and systematic release of water from Oyan Dam to prevent flooding of the downstream communities;
He, however, appealed to the people to support government efforts by complementing the state government through regular clearing of drains in their frontages to ensure free-flow of storm water.
