Flash Flood Warnings in the United States
In the United States, a flash flood warning is a critical alert indicating that flash flooding is imminent or currently happening. You must take immediate action for your safety. The National Weather Service (NWS) issues these warnings based on rainfall rates, river gauges, or reports of rapidly rising water in areas prone to flooding.
What Is a Flash Flood Warning?
A flash flood warning means that flash flooding is already taking place or is expected to occur within the next six hours. This warning applies to areas especially susceptible to flooding, including:
– Urban environments with poor drainage systems
– Steep terrain, such as mountains or canyons
– Areas near rivers or creeks that can overflow quickly
– Locations experiencing heavy rainfall in a short time (for example, several inches within an hour)
How to Stay Informed
1. Wireless Emergency Alerts (WEA): Ensure your cell phone can receive WEA, a vital public safety alert system in the U.S. Always keep this feature enabled.
2. NOAA Weather Radio: These radios are essential for receiving reliable, real-time weather updates, including flash flood warnings. They broadcast on specific frequencies and deliver emergency alerts.
3. Local News and Radio: Stay close to TV and radio stations for real-time alerts and updates during severe weather events.
4. FEMA App: Download the FEMA app to receive instant emergency alerts regarding flash floods or any severe weather events in your vicinity.
5. NWS Website: Visit the National Weather Service’s official website or follow them on social media for crucial updates.
What to Do if You are Under a Flash Flood Warning
– Move to Higher Ground: If you’re in a flood-prone area, do not hesitate, immediately head to higher ground. Even a small amount of moving water can pose a serious threat.
– Avoid Driving: Flash floods can wash out or submerge roads. Do not try to drive through flooded areas. Always remember: “Turn Around, Don’t Drown.”
– Evacuate if Necessary: If local authorities issue an evacuation order, leave immediately. Take routes to higher ground and steer clear of flooded zones.
– Stay Indoors: If it’s safe inside, remain indoors and keep away from windows, doors, and any vulnerable areas where flooding could occur.
– Monitor Local Alerts: Continuously check local media or official weather channels for up-to-date information.
