What & Why

A flash flood warning is issued when a flash flood is imminent or already occurring. This type of flood develops rapidly, often within minutes or a few hours of excessive rainfall. Unlike river floods, flash floods can occur in areas not typically considered flood-prone, such as urban streets, canyons, and low-lying areas. — Kohl's Toms River NJ: Hours, Location & Services

1. Stay Informed:
   • Monitor weather reports from the NWS, local news, and reliable sources. Websites and apps like the National Weather Service and local news channels are essential resources. Also, tune into NOAA Weather Radio for continuous updates.
   • Sign up for emergency alerts from your local government. The City of Los Angeles and Los Angeles County offer alerts via text, email, and phone calls.
2. Take Immediate Action:
   • Move to Higher Ground: The most important step is to move to safety immediately. Go to higher ground if you are in a flood-prone area. Get out of areas subject to flooding.
   • Avoid Floodwaters: Do not walk, swim, or drive through floodwaters. The depth of the water is often underestimated, and currents can be surprisingly strong. Also, floodwaters can be contaminated with hazardous materials.
   • Seek Shelter: If you are unable to evacuate, go inside the sturdiest building you can find. Stay away from windows and doors.
3. Protect Your Property:
   • Elevate Appliances: If time allows, move essential appliances, furniture, and valuables to higher levels of your home.
   • Secure Outdoor Items: Bring in outdoor furniture, trash cans, and other items that could be carried away by floodwaters.
   • Turn off Utilities: If advised by authorities, turn off gas, electricity, and water to prevent damage and hazards.
4. During and After the Flood:
   • Continue Monitoring: Keep listening to weather updates even after the rain stops, as flash floods can continue for several hours.
   • Avoid Damaged Areas: Do not enter areas that have been flooded until authorities declare it safe. Be aware of hazards like downed power lines and unstable structures.
   • Report Damage: Contact your insurance company and report any damage to your property. Contact the relevant local authorities to report any infrastructural damage.

Examples & Use Cases

• Canyon Residents: Residents living in canyons, such as those in Malibu or the Santa Monica Mountains, are at high risk due to the rapid runoff from steep slopes. During a flash flood warning, they should evacuate immediately to a pre-designated safe location.
• Urban Areas: Low-lying areas in urban environments, such as near the Los Angeles River or areas with poor drainage, are prone to flooding. During a warning, residents and drivers should avoid these areas entirely.
• Construction Sites: Construction sites often have exposed soil and disturbed landscapes, increasing the risk of runoff. Construction workers should be informed and follow safety protocols during a flash flood warning.
• Emergency Response: Local emergency services like the Los Angeles Fire Department (LAFD) and Los Angeles County Sheriff's Department (LASD) coordinate search and rescue efforts and manage evacuations during a flash flood warning. Understanding their protocols and following their instructions is crucial.

Best Practices & Common Mistakes

Best Practices:

• Emergency Preparedness: Have an emergency kit ready with essentials like water, food, a first-aid kit, flashlights, and a battery-powered radio.
• Flood Insurance: Ensure you have adequate flood insurance, as standard homeowner's insurance doesn't cover flood damage.
• Family Communication Plan: Establish a plan for communicating with family members during emergencies, including meeting points and contact information.
• Know Your Zone: Familiarize yourself with flood zones in your area using FEMA’s flood map service center. Learn which areas are prone to flooding.

Common Mistakes to Avoid:

• Ignoring Warnings: The most dangerous mistake is ignoring flash flood warnings. Always take them seriously.
• Driving Through Floodwaters: Never drive through flooded roads. The depth and current are often underestimated, and vehicles can be swept away.
• Underestimating the Risk: Flash floods can occur quickly and unexpectedly. Do not assume that you are safe just because it is not raining at your location.
• Lack of Preparation: Failing to prepare in advance, such as not having an emergency kit or a family communication plan, can put you at greater risk.
