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.
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.
Cause outages, disrupt transportation, damage buildings, and create landslides.
