But what exactly is a flash flood emergency, and how does it differ from a regular flash flood warning? Flash flood warnings are familiar—they're issued when flooding is happening or expected soon. In 2023, the NWS issued almost 3,700 of these warnings, often covering flooded streets and low-lying areas.
Now, enter the flash flood emergency. These alerts go beyond the typical warnings, signifying a major threat to life and the potential for catastrophic damage. Examples of triggers for such emergencies include confirmation from local or state emergency managers about rising water posing a life-threatening situation, or when river gauges indicate water reaching major flood levels.
When you receive a flash flood emergency alert on your smartphone, it's time to act swiftly. Move to higher ground immediately and avoid traveling unless escaping a flooded area or directed to evacuate by local authorities. Walking or driving through floodwaters is risky, as water depth can be deceiving, and the road underneath might be washed out.
Looking back at 2023, several flash flood emergencies stand out. In Kernville, California, heavy rain on a massive Sierra snowpack triggered an emergency in mid-March. Ft. Lauderdale, Florida, experienced historic flash flooding with over 20 inches of rain in less than 24 hours a month later. In mid-July, New York's Lower Hudson Valley and parts of Vermont faced torrential rain, resulting in multiple flash flood emergencies.
These events caused at least $1 billion in damages each, underlining the destructive nature of flash flood emergencies. Smaller-scale emergencies in places like Leominster, Massachusetts, and Georgetown, South Carolina, also brought widespread road flooding and stranded vehicles.
When a flash flood emergency is issued for your area, treat it with the same urgency as a tornado warning. Immediate action could be the key to saving lives. So, stay informed, stay safe, and be prepared for whatever weather challenges come your way.
Signing up for alerts, like the Morning Brief email newsletter from The Weather Channel, can keep you informed about potential emergencies in your area. These updates provide crucial information and tips to help you stay ahead of severe weather.
Understanding the difference between a flash flood warning and a flash flood emergency is essential. While warnings highlight ongoing or expected flooding, emergencies indicate a significant threat to life and property, demanding immediate attention.
Flash flood emergencies can occur due to various factors, such as rapid water rise confirmed by emergency managers, the potential for water to reach dangerous levels in typically safe areas, or the deployment of swift-water rescue teams in response to an unusually severe flood.
In 2023, the impact of flash flood emergencies was evident. In mid-March, Kernville, California faced severe flooding triggered by heavy rain on a substantial Sierra snowpack. Ft. Lauderdale, Florida witnessed historic flash flooding in April with over 20 inches of rain in less than 24 hours. July brought torrential rain to New York's Lower Hudson Valley and parts of Vermont, causing multiple flash flood emergencies.
These events serve as a reminder of the importance of heeding emergency alerts and taking immediate action. Flash flood emergencies are not to be taken lightly, and preparedness can make a significant difference.
Remember, your smartphone will emit a loud alert in case of a flash flood emergency, prompting you to move to higher ground. Avoid unnecessary travel, as roads may be impassable, and flooded areas pose a serious risk. Even a small amount of moving water can be hazardous, potentially sweeping you off your feet or carrying away your vehicle.
In summary, staying informed, having an emergency plan, and acting promptly during flash flood emergencies are crucial steps to ensure your safety and the safety of those around you. By understanding the significance of these alerts and being prepared, you can navigate through challenging weather events with confidence.
