Season/2012 Flood

Nigeria, like the rest of West Africa and other tropical lands, has only two seasons. These are the Dry season and the Rainy season. The dry season is accompanied by a dust laden airmass from the Sahara Desert, locally known as Harmattan, or by its main name, The Tropical Continental (CT) airmass, while the rainy season is heavily influenced by an airmass originating from the south Atlantic Ocean, locally known as the south west wind, or by its main name, The Tropical Maritime (MT) airmass. These two major wind systems in Nigeria are known as the trade winds.
The region Onikwu/Ndoni is flood prone communities, this is because the inland part of Rivers state consists of tropical rainforest; towards the coast the typical Niger Delta environment features many mangrove swamps, beside that the communities lies along the Niger Delta Central coastal region.

In October 2012, villages like Ndoni, Ase-Azaga, Isukwa, Odugiri. Agwe, Onikwu, Ugbaja, Isala and Ogbe-Ogene were badly hit by the flood.
