What is a flood warning?
A flood warning means flooding is happening or about to happen. The NWS issues it both for rivers at forecast points (river flood warnings) and for areas where water ponds or runs off (areal flood warnings); AreaZine counts both. A warning means the hazard is happening, about to happen, or very likely: act now to protect people and property. The national record · Every warning type in Oregon.
