If in a car, get out and seek shelter. Do not try to outrun a tornado in a car. Tornadoes can pick up a car and throw it through the air. DO NOT get under a vehicle. Flash floods are rapidly developing floods that can occur with little or no warning after an intense rainfall, a severe thunderstorm, or when a dam, levee or dike breaks.
Floods are a common natural hazard.
Know your area's flood risks and obtain flood insurance if possible. Prepare a family evacuation plan. Do a practice through once a year. Listen to your local radio station to keep track of weather patterns. Keep your car's gas tank filled.
