What is a Flash Flood Warning?


This warning signifies a short duration of intense flooding of counties, communities, streams, or urban areas with high peak rate of flow. Flash floods may result from such things as torrential downpours, dam breaks, or ice jam breaks. They are issued by the local National Weather Service Office for 4 hours or less. Since flash flooding can occur in severe thunderstorms, this type of warning can be combined with either a Tornado Warning or a Severe Thunderstorm Warning. Source:
