Introduction
Severe thunderstorms are a common and dangerous weather phenomenon in the United States and around the world. They can produce a range of hazards, including large hail, damaging winds, flash flooding, and even tornadoes. Understanding the nature of severe thunderstorm warnings and how to respond to them is crucial for personal safety.

What & Why
A severe thunderstorm warning is a critical alert issued by the NWS to inform the public of an immediate threat. It means that a severe thunderstorm is occurring or is expected imminently in the warned area. The criteria for issuing a severe thunderstorm warning include: — Was Ed Gein Special? The Disturbing Case
- Large hail: Hail that is one inch in diameter or larger.
- Damaging winds: Wind gusts of 58 mph (50 knots) or greater.
- Tornadoes: Although tornadoes trigger their own specific warnings (tornado warnings), a severe thunderstorm can sometimes produce a tornado. A severe thunderstorm warning may also indicate the potential for a tornado.
The purpose of the warning is to give people enough time to take protective measures. It allows individuals to seek shelter, secure property, and avoid potential harm. When a warning is issued, it typically covers a specific geographic area, such as a county or part of a county, and includes information about the expected hazards, the time the warning is in effect, and the location of the severe thunderstorm. — New Milford, CT Zip Code: Find It Here!

- Increased Risk of Accidents: Hazardous conditions caused by severe weather increase the risk of car accidents and other incidents.
How-To / Steps / Framework Application
When a severe thunderstorm warning is issued, it is crucial to act quickly and decisively. Here's a step-by-step guide to follow:
- Seek Immediate Shelter: The safest place to be during a severe thunderstorm is indoors in a sturdy building. Go to an interior room, away from windows, doors, and outside walls.
- Stay Informed: Keep track of the storm's progress and updates by monitoring NOAA Weather Radio, local news, or reputable weather apps on your phone. The NWS will provide regular updates and revisions to the warning.
- Avoid Hazardous Locations: Stay away from windows, doors, and outside walls. Do not go outside to watch the storm. If you are driving, pull over to a safe location away from trees or power lines and remain in your vehicle.
- Protect Yourself from Lightning: If you are outdoors, seek shelter immediately. Lightning can strike up to 10 miles away from the storm. Avoid contact with metal objects and stay away from tall trees or other potential hazards.
- Prepare for Power Outages: Have flashlights, batteries, and a first-aid kit ready in case of a power outage. Unplug sensitive electronic equipment to protect them from power surges.
- Monitor for Tornadoes: Be aware of the possibility of tornadoes, even if a tornado warning has not been issued. If you observe a funnel cloud, rotating debris, or hear a loud roaring sound, take immediate shelter.
- Stay Updated: Keep listening to NOAA Weather Radio or local news. The warning will give an expiration time, but severe weather can sometimes last beyond that time. Don't go outside until the storm has passed and it is safe to do so.
Examples & Use Cases
Understanding how to respond to severe thunderstorm warnings is critical in various scenarios:
- At Home: If a warning is issued, everyone at home should immediately move to an interior room away from windows and doors. Close and secure windows and doors, and stay informed through reliable weather sources.
- At Work: If your workplace is under a severe thunderstorm warning, follow your company's emergency plan. Seek shelter in an interior room and stay informed. Avoid windows and doors and wait for the all-clear signal from the weather service or your workplace.
- In Public Spaces: When in public spaces such as shopping malls, schools, or public buildings, follow the instructions provided by the building management. Go to designated shelter areas if available, and stay informed via announcements or emergency broadcasts.
- While Driving: If a severe thunderstorm warning is issued while you're driving, pull over to a safe location away from trees and power lines. Turn on your hazard lights and stay inside your vehicle until the storm passes. Avoid driving through flooded areas.
- Camping or Outdoor Activities: If you are camping or participating in outdoor activities, immediately seek shelter in a sturdy building or vehicle. Avoid open areas, tall trees, and water. If no shelter is available, crouch low to the ground and protect your head.
