Story highlights Lagos, one of Africa's most populous cities has been hit by torrential downpour

Poor drainage systems and weak urban planning have compounded effects of the rainfall

Lagos, Nigeria (CNN) Lagos, one of Africa's most populous cities, has been hit by torrential downpour and thunderstorms over the weekend that has left many parts of the city flooded.

Residents in the Lekki and Victoria Island suburbs woke up on Saturday morning to flooding in their homes and their cars submerged under water.

One brave resident took to swimming in the infested waters on Lekki road, an affluent suburb that is home to some of the most expensive real estate in the coastal city. A crocodile was spotted along Chevron Drive in the same neighborhood.
