Flood watch, flood advisory, flood warning or flash flood warning near Lagos: what each means

The National Weather Service flood products, from least to most urgent. The live status above shows which, if any, is in effect within 300 km of Lagos.

Flood Watch

Conditions favor flooding or flash flooding, usually within the next 48 hours and for river flooding sometimes several days ahead. Flooding is possible, not certain. Review your routes and be ready to act.

Flood Advisory

Minor or nuisance flooding is expected or occurring, such as water ponding on roads or small streams edging out of their banks. An inconvenience rather than a threat to life if you avoid flooded roads.

Flood Warning

Flooding is imminent or occurring, usually from rivers or streams rising over hours to days. Never drive through flooded roads; move to higher ground if told to.

Flash Flood Warning

Rapid, life-threatening flooding is imminent or occurring, usually within 6 hours of heavy rain or a dam or levee failure. Move to higher ground immediately. A Flash Flood Emergency is the rare top tier for catastrophic flooding.

River flood products are tied to official flood stages at specific gauges, so a warning can be in effect for one river reach and not the next. Coastal flooding has its own Coastal Flood Advisory, Watch and Warning.
