Severe Thunderstorm Warning: What You Need To Know

A severe thunderstorm warning is a critical alert issued by the National Weather Service (NWS) when radar or spotters indicate a thunderstorm is producing, or is forecast to produce, large hail (1 inch in diameter or greater), winds of 58 mph or higher, and/or a tornado. Receiving this warning means you must take immediate action to protect yourself.

This article provides comprehensive information about severe thunderstorm warnings, including how they are issued, what they mean, and how to stay safe.

What Triggers a Severe Thunderstorm Warning?

Understanding the criteria that trigger a severe thunderstorm warning is crucial. The NWS issues these warnings based on:

• Observed Conditions: Real-time reports from trained spotters or damage assessments indicating large hail or high winds.
• Radar Data: Analysis of weather radar imagery showing characteristics associated with severe thunderstorms, such as strong rotation, hail signatures, and intense rainfall rates.
• Forecast Models: When weather models predict the likelihood of severe weather development. These models are essential for giving advanced notice.

How Does the NWS Issue Warnings?

The NWS uses various methods to disseminate warnings:

• Weather Radios: NOAA Weather Radio is a dedicated broadcast system providing continuous weather information.
• Wireless Emergency Alerts (WEA): These are sent to mobile phones, similar to Amber Alerts, and can provide location-specific warnings.
• Local Media: TV stations, radio stations, and online news outlets relay warnings to the public.
• Social Media and Websites: Official NWS channels and weather apps provide up-to-the-minute updates.

What Does a Severe Thunderstorm Warning Mean for You?

When a severe thunderstorm warning is issued, it means dangerous weather conditions are imminent or occurring in your area. This is not the time to be casual. It is vital to take immediate safety precautions.

Immediate Actions to Take:

• Seek Shelter: Go inside a sturdy building. Avoid sheds, mobile homes, and vehicles, as these offer limited protection.
• Stay Away from Windows: Windows can shatter from high winds or flying debris.
• Monitor Weather Updates: Continue to check local media or the NWS for the latest information.
• Be Aware of Hazards: If outdoors, watch for lightning, large hail, and strong winds.

Differences Between a Watch and a Warning

It's important to distinguish between a severe thunderstorm watch and a severe thunderstorm warning:

• Severe Thunderstorm Watch: Issued when conditions are favorable for severe thunderstorms to develop in the watch area. This means you should be prepared.
• Severe Thunderstorm Warning: Issued when a severe thunderstorm has been detected, is indicated by radar, or is reported by spotters. This requires immediate action.

Safety During a Severe Thunderstorm

Staying safe during a severe thunderstorm involves a few key steps:

• Indoor Safety: Move to an interior room, away from windows. Avoid using wired electronics and plumbing, as these can conduct electricity.
• Outdoor Safety: If caught outside, seek shelter immediately. If no shelter is available, try to find a low-lying area and crouch down, protecting your head and neck.
• Vehicle Safety: If you are in a vehicle, try to pull over safely and stay inside. Avoid parking under trees or power lines.

Role of the National Weather Service (NWS)

The National Weather Service plays a critical role in monitoring and forecasting severe thunderstorms. Using advanced technology and a network of trained observers, the NWS provides timely warnings and information to the public.

• Radar Technology: Doppler radar systems detect precipitation, wind speed, and the potential for severe weather.
• Spotter Networks: Trained volunteers across the country report weather conditions to the NWS.

• Flash Flooding: Heavy rainfall can cause rapid flooding, especially in low-lying areas and near streams.
• Lightning: Can strike people and ignite fires, posing a serious risk to life and property.
