Note: The National Oceanographic and Atmospheric Association (NOAA), marine radio and local radio, television stations, and outdoor sirens will broadcast official warnings when a flash flood is possible. Sign up for NOAA text and phone alerts to stay informed.
FLASH FLOOD WATCH VS. FLASH FLOOD WARNING
A flash flood watch means a flash flood is possible. If the watch escalates to a warning, flooding is already occurring or will occur soon, and you should take immediate precautions.
HOW TO PREPARE FOR FLASH FLOODS
Since flash floods can occur with little warning, advanced preparation is essential.
- Create an emergency plan. Identify safe evacuation routes and higher ground in your area. Ensure everyone in your family or business is familiar with them and knows what to do when a flash flood warning is issued.
- Build an emergency supply kit. Pack a bag with essential supplies such as a flashlight, medicine, non-perishable food, and three days of water per person. Mobile device chargers, spare batteries, and a portable hand-crank radio are also important. Your emergency kit should be easily accessible so you can grab it and go if an evacuation warning is issued.
- Prepare your property. Simple preventive maintenance, like clearing your gutters and securing outdoor furniture, can help minimize flood damage.
- Buy flood insurance. Since standard insurance policies don’t typically cover flooding, it’s important that you protect your property with valuable flood insurance.
STAYING SAFER WHEN A FLASH FLOOD WARNING IS ISSUED
Immediate action is essential if a flash flood warning is issued in your area.
- Seek higher ground. Consider relocating to an elevated area like a hill, a sturdy building with multiple floors, or a designated evacuation center.
- Avoid walking or driving through floodwaters. In addition to powerful currents, floodwater may contain harmful contaminants or conceal dangerous debris. If the path to higher ground is blocked, seek another route.
- Avoid bridges over fast-moving water. Flash floods can wash away bridges without warning.
- Check for updates from local authorities. Emergency directives may change after a flash flood warning is issued. Stay tuned to local emergency radio stations or look for updates on your mobile device.
WHAT TO DO AFTER A FLASH FLOOD
Wait for authorities to confirm that it is safe to return to your property. When you do return, be sure to:
- Avoid standing water and downed power lines. Water may conceal dangerous debris, and power lines may still be active.
- Inspect your property. Check for structural damage, water infiltration, and electrical issues.
- Seek professional help. Contact electricians and plumbers to assess and repair any damage that may compromise the safety or functionality of your property.
- Document the damage. Take photographs or video of any damage for insurance purposes.
