Understanding the Difference: Warnings vs. Alerts

Knowing the difference between a flash flood warning, watch, and advisory is the first step in flood safety. These terms represent varying levels of urgency and potential danger:

• Flash Flood Warning: This is the most serious alert. A flash flood warning means that a flash flood is occurring now or is imminent. Flooding is already happening or will happen very soon in your area. Take immediate action. This is not the time to wait and see.

• Flash Flood Watch: A flash flood watch means that conditions are favorable for flash flooding to develop. While flooding isn't currently happening, the potential is high. This is your time to prepare. Monitor weather reports closely and be ready to act quickly if a warning is issued. This is a crucial time to review your flood preparedness plan and ensure your emergency kit is readily accessible.

• Flash Flood Advisory: A flash flood advisory indicates that flash flooding is possible. The threat is less immediate than a warning, but you should still monitor the situation closely and be prepared to take action if conditions worsen. Pay close attention to local news and weather updates.

How to Receive Flash Flood Warnings and Alerts

Staying informed is critical during severe weather events. Here are several reliable ways to receive timely flash flood warnings and alerts:

• NOAA Weather Radio: This is arguably the most reliable source of weather alerts. A NOAA Weather Radio with Specific Area Message Encoding (SAME) technology will only alert you to warnings issued for your specific location, filtering out extraneous alerts from other areas. Crucially, it works even during power outages, ensuring you remain informed regardless of circumstances.

• Smartphone Apps: Many weather apps, such as those from the Weather Channel, AccuWeather, and the National Weather Service, offer push notifications for severe weather alerts, including flash flood warnings. Make sure you enable location services and alert settings for these apps to receive timely updates.

• Emergency Alert System (EAS): The EAS broadcasts critical weather alerts, including flash flood warnings, through television and radio stations. While convenient, this system may be interrupted during power outages or if your TV/Radio is off.

• Local News and Media: Local news channels and websites often provide up-to-the-minute weather reports and alerts tailored to your specific region. Consider setting up alerts on their websites or apps.

Creating a Flash Flood Preparedness Plan

Proactive preparation is your best defense against flash floods. Developing a comprehensive preparedness plan can significantly reduce risk and protect your family:

• Develop an Evacuation Plan: Identify multiple evacuation routes from your home and know where to go if you need to evacuate. Pre-determine a meeting point for family members in case you become separated. Having a backup location outside of your immediate area is also advisable in the event of widespread flooding.

• Assemble an Emergency Kit: Your emergency kit should include essential supplies for at least 72 hours, such as bottled water, non-perishable food, a first-aid kit, medications, flashlights, batteries, and blankets. Include important documents in waterproof containers as well.

• Know Your Risk: Identify areas in your community that are prone to flash flooding. This information might be available through your local government or emergency management services. Understanding your risk will help you make informed decisions during a flash flood watch or warning.

• Secure Your Property: Take steps to protect your home and belongings. Elevate valuable items, reinforce structures prone to water damage, and consider installing flood barriers if appropriate for your situation.

What to Do During a Flash Flood Warning

When a flash flood warning is issued, time is of the essence. Immediate action is critical:

• Evacuate Immediately: Don't wait for the water to rise. Follow your pre-planned evacuation route and head to higher ground. Heeding a warning is far better than risking your life.

• Move to Higher Ground: Seek shelter in a sturdy building or on higher ground well away from flood-prone areas. Avoid basements and low-lying areas.

• Avoid Driving or Walking Through Floodwaters: Floodwaters can be deceptively dangerous. The water may be deeper or faster moving than it appears, and electrical hazards can be deadly. Never attempt to drive or walk through floodwaters. The current could sweep you away, and hidden debris can inflict injuries.

• Stay Informed: Continue to monitor weather updates throughout the duration of the flash flood. Remain aware of evolving conditions and updated instructions from emergency services.

Flash floods are a severe threat, but with proper preparedness and a clear understanding of warnings and alerts, you can significantly reduce your risk.
