Heavy seasonal rains have caused flash floods in Nigeria's biggest city, Lagos, with videos shared on social media documenting the damage caused over the weekend.
One showed a man crawling on top of a bus half-submerged in a torrent of murky water, while another showed a women stumbling across a deluge of water on an impassable street.
And this is only at the beginning of the raining season.
But the Permanent Secretary for Drainage in Lagos state, Lekan Shodeinde, is bullish about the situation.
"As of today, every part of the state that was seemingly underwater is dry. So we wouldn't see it as a major cause of alarm of flooding per se," he told the BBC Focus on Africa programme.
"There are parts of the world that are witnessing worst cases than Lagos."
The authorities are reconstructing and improving the city's drainage system, he said but warned residents against taking risks in flooded areas.
"Where you see a flowing torrential body of water, we should just avoid it. We shouldn't drive through it. Even if you are driving the biggest car in the car, don't attempt to wade through it," he said.
He also urged residents to stop panicking.
"Flooding will happen, but I can assure you that when it happens it will flow out within two to three hours. So no need for panicking. The water will come and will go."
