Do not walk through moving water. Six inches of moving water can make you fall. If you have to walk in water, walk where the water is not moving. Use a stick to check the firmness of the ground in front of you.
Do not drive into flooded areas. If floodwaters rise around your car, abandon the car and move to higher ground if you can do so safely. You and the vehicle can be quickly swept away. It can take only a foot or two of water to float or sweep away your vehicle.
Listen to NOAA weather radio, a battery-operated radio, or television for the latest emergency information. Use phones only for emergency calls. Stay away from damaged areas. Return home only when authorities say it is safe.

Do not attempt to walk across flowing streams or drive through flooded roadways.
