What is a Severe Thunderstorm Warning?

A severe thunderstorm warning is issued by the National Weather Service (NWS) when a severe thunderstorm has been spotted by weather radar or reported by trained spotters. Unlike a severe thunderstorm watch, which indicates conditions are favorable for severe thunderstorms to develop, a warning means severe weather is happening now in your area. This is a serious alert requiring immediate action to ensure your safety and the safety of your loved ones. These storms can bring incredibly dangerous conditions, including damaging winds, large hail, and even tornadoes.

Understanding the Dangers of Severe Thunderstorms

Severe thunderstorms pose significant threats due to their intensity and unpredictable nature. The key dangers include:

• Damaging Winds: Gusts exceeding 58 mph can cause significant damage to property, uproot trees, and down power lines. These high winds can be incredibly dangerous, even potentially deadly.
• Large Hail: Hailstones larger than one inch in diameter are considered large hail and can cause significant damage to vehicles, homes, and crops. Larger hail can also injure people and animals.
• Flash Flooding: Intense rainfall associated with severe thunderstorms can lead to rapid and dangerous flash flooding, especially in low-lying areas and near bodies of water. Never drive through flooded areas.
• Tornadoes: While not all severe thunderstorms produce tornadoes, they are a significant risk. A tornado warning is a separate but related alert that indicates a tornado has been sighted or indicated by radar.

Safety Measures During a Severe Thunderstorm Warning

When a severe thunderstorm warning is issued for your area, immediate action is crucial. Follow these safety guidelines:

1. Go indoors immediately: Seek shelter in a sturdy building, away from windows. A basement is ideal; if you don’t have one, go to an interior room on the lowest level.
2. Stay away from windows: Flying debris poses a significant threat during severe weather. Stay away from windows and doors.
3. Unplug electronic devices: Power surges from lightning strikes can damage electronics. Unplug appliances and other sensitive equipment.
4. Avoid water: Never touch water during a thunderstorm, as it is an excellent conductor of electricity. Get out of pools, lakes, and bathtubs.
5. Stay informed: Keep a weather radio tuned to your local NWS station or monitor weather alerts on your smartphone or computer. Pay close attention to any updates or changes in the warning.
6. Be aware of flash flooding: If you're in an area prone to flash flooding, move to higher ground immediately. Never drive through floodwaters.

After the Severe Thunderstorm Warning

Even after the severe thunderstorm warning has expired, remain cautious. Assess any damage to your property and report it to the appropriate authorities. Be aware of downed power lines and avoid contact. Check on your neighbors, particularly the elderly or those with disabilities, to ensure their safety.

Staying Prepared for Severe Weather

Preparing in advance is key to minimizing the risks associated with severe thunderstorms. Develop a family emergency plan, including a designated safe room and communication protocols. Ensure you have a well-stocked emergency kit, including flashlights, batteries, water, non-perishable food, and first-aid supplies. Familiarize yourself with your local warning systems and understand the difference between watches and warnings. Staying informed and prepared can greatly reduce the risks during severe thunderstorm events.
