FG Issues Safety Advisory to Residents
The ministry urged residents in high-risk communities to take urgent precautionary measures to reduce potential impact.
It advised communities in critical zones to maintain flood watch, identify evacuation routes, and avoid building or trading in flood-prone areas.
“Communities classified as Critical should maintain immediate flood watch, identify evacuation routes, protect vulnerable households,” the advisory stated.
For high-risk areas, the ministry called for intensified drainage clearance, monitoring of waterways, and improved community reporting of rising water levels.
Rising Concern Over Seasonal Flooding
The warning comes amid the peak of Nigeria’s rainy season, raising concerns over possible displacement of residents, destruction of property, and disruption of economic activities in vulnerable areas.
Authorities have urged state governments and emergency agencies to step up preparedness measures to prevent avoidable losses.
