What is a Flash Flood Warning?
A flash flood warning is a severe weather warning product of the National Weather Service that is issued by national weather forecasting agencies throughout the world to alert the public that a flash flood is imminent or occurring in the warned area. A flash flood is a sudden, violent flood after a heavy rain, or occasionally after a dam break. Rainfall intensity and duration, topography, soil conditions, and ground cover contribute to flash flooding.
What is the difference between a Flash Flood Warning and a Flood Watch?
A flash flood warning is more urgent than a flood watch. A flood watch means that conditions are favorable for flash flooding, while a flash flood warning means that a flash flood is imminent or occurring. If you are in an area that is under a flash flood warning, you should take immediate action to move to higher ground.

Flash floods are a type of flood that occurs quickly and with little or no warning. They can be caused by heavy rainfall, melting snow, or a dam break. Flash floods can happen anywhere, but they are most common in mountainous areas, river valleys, and floodplains.
Flash floods are dangerous because they can be very powerful and can carry objects weighing tons. They can also contain debris, such as rocks, trees, and cars. Flash floods can cause drowning, injuries, and property damage.
