Already struggling to help the many flooded communities around the country, Nigeria’s emergency response agency warned the nation on Thursday that the height of the rainy season has still not arrived and that people should brace themselves for more floods ahead.

The National Emergency Management Agency (NEMA) is preparing for more flood emergencies, the director General Audu Bida told reporters in Abuja on Thursday but said that local governments needed to improve their preparedness also.

“Emergency management must be seen as a collective responsibility and not just the function of NEMA,” Audu said.

At least 26 people have killed in the last month by floods; thousands more have been left homeless.
