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