What a flood warning means
A flood warning is issued when flooding is occurring or imminent but develops more slowly than a flash flood. River flood warnings are tied to forecast points on a river or stream and include the expected crest and the flood stage, which tells you how high the water will rise compared with the level where damage begins.
