Flooding is a temporary overflow of water onto land that is normally dry. Floods are the most common disaster in the United States. Failing to evacuate flooded areas or entering flood waters can lead to injury or death.
Floods may:
- Cause outages, disrupt transportation, damage buildings and create landslides.
- Develop slowly or quickly. Flash floods can come with no warning.
- Result from rain, snow, coastal storms, storm surges and overflows of dams and other water systems.
