Lagos to experience 240-day rainfall from March 19- Commissioner for Environment, Tunji Bello says

Lagos Island is expected to have a rainfall onset date of March 19, with an error margin of three days, while its cessation date is expected to be November 26. It is also expected that Lagos Island will have about 252 days of rainfall and about 1,714 millimeters of rainfall over the year.
It can be deduced that Lagos State shall experience a rainy season of 240-270 days, while the maximum annual rainfall is predicted to be 1,750 millimeters. Year 2020 will likely experience days with extremely high rainfall amount which may result in flooding.
Another contributory factor to possible flooding in the state is sea level rise. This poses the biggest risk to coastal areas and the state’s drainage infrastructure, as anytime there is high tidal movement, it may lock up the discharged points of drainage channels and until it recedes, there will be no discharge.
Such occurrences also caused back flows, resulting in flooding but as soon as the Lagoon recedes, all generated storm water run-off will immediately discharge and our roads will be free.” Bello said
