The Lagos state government has asked residents to prepare for the rainy season, as the state is expected to witness between 240 to 270 rainy days in 2020.
According to Commissioner for the Environment, Tunji Bello, who stated this during a press conference on seasonal rain forecasts for 2020 and flood prevention in the state on Tuesday, added that maximum annual precipitation is estimated at 1,750 mm.
Mr. Bello, while referring to a report obtained by the Nigeria Meteorological Services (NIMET), stated that the first expected start of the rainy season is March 17, with other areas to follow.
He added that the rainy season must end before November 22 in Surulere, with other areas to follow.
“Ikeja is expected to be about 1526 mm, while Badagry’s is 1750 mm, Lagos Island is 1714 mm, Ikorodu is 1690 mm and Epe is 1730 mm of rain.
“The island of Lagos was expected to have a rain start date of 19 March with a margin of seize of three days, while its cessation date should be 26 November,” he said.
The Environment Commissioner noted that this year’s forecast by NiMeT is based on the global consensus that the southern El-Nino (ENSO) oscillation is in the neutral phase, which will continue until August or September.
Bello explained that residents of coastal areas will witness flash floods that he describes as “natural”, but will disappear in a matter of time if the drains are clean.
“As long as the drains are clean, we must be sure that, in a matter of time, the flood will disappear.
“It should be noted that whenever the level of the Lagoon rises, it can“ lock ”the drainage channels at the discharge points and until it recedes, there will be no discharge. Events like these also cause reflux, resulting in floods ”, he emphasized.
He disclosed: “The Lagos state government has established synergy and partnership with the Ogun-Osun River Basin Authority and this has ensured control and monitoring of the constant and systematic release of water from the Oyan dam to prevent flooding in the downstream communities. ;
According to him, since last year, the emergency flood-fighting gang of the Ministry’s Drainage Maintenance Department has been disfellowshipping and constantly working on collectors and secondary conduits, to allow them to discharge efficiently.
The Commissioner advised the inhabitants of Lagos who live along wetlands, coastal areas and swamps close to large rivers, always on the alert and ready to move when necessary.
He called on Lagos residents to give up acts that could lead to flooding and indiscriminate dumping of waste in unauthorized locations.
