Severe Thunderstorm Watch: What Does It Mean?
Severe thunderstorms can bring damaging winds, large hail, and even tornadoes. A severe thunderstorm watch means that conditions are favorable for these storms to develop in your area. It's important to understand what a watch means and how to prepare.
What is a Severe Thunderstorm Watch?
A severe thunderstorm watch is issued by the National Weather Service (NWS) when conditions are favorable for severe thunderstorms to develop in a specific area. This means that the atmosphere is unstable and has enough moisture and wind shear to support the formation of strong storms. A watch typically covers a large area and lasts for several hours.
Key elements of a severe thunderstorm watch:
- Issued by the National Weather Service (NWS)
- Indicates favorable conditions for severe thunderstorms
- Covers a specific area for a set period
- Serves as an alert to be prepared for potential severe weather
Understanding the Difference: Watch vs. Warning
It's crucial to differentiate between a severe thunderstorm watch and a severe thunderstorm warning. While a watch means conditions are favorable, a warning means a severe thunderstorm is occurring or is imminent in your area.
| Feature | Severe Thunderstorm Watch | Severe Thunderstorm Warning |
|---|---|---|
| Definition | Conditions favorable for severe thunderstorms | Severe thunderstorm is occurring or imminent |
| Action | Be prepared; monitor weather updates | Take immediate action; seek shelter |
| Area Covered | Large area | Smaller, more specific area |
| Duration | Several hours | Shorter duration, typically 30-60 minutes |
What to Do During a Severe Thunderstorm Watch
- Stay Informed: Monitor weather updates from the NWS, local news, and reliable weather apps.
- Have a Plan: Discuss a safety plan with your family, including where to seek shelter.
- Prepare Your Home: Secure outdoor objects, close windows and doors, and unplug electronic devices.
- Be Ready to Act: If a warning is issued, take immediate action and seek shelter.
Safety Tips During a Severe Thunderstorm
- Seek Shelter: Go indoors to a sturdy building, away from windows and doors. The lowest level is usually the safest.
- Avoid Water: Do not shower, bathe, or wash dishes during a thunderstorm, as lightning can travel through plumbing.
- Stay Away from Electronics: Avoid using computers, TVs, and other electronic devices.
- If Outdoors: Seek shelter in a low-lying area, away from trees and power lines. Crouch down with your head between your knees.
- In a Car: Pull over to the side of the road and turn on your hazard lights. Stay in the car with your seatbelt fastened until the storm passes.

- Large Hail: Hailstones of 1 inch in diameter or larger can damage vehicles, roofs, and crops.
- Flash Flooding: Heavy rainfall can cause flash flooding, especially in urban areas and low-lying areas.
- Tornadoes: Severe thunderstorms can sometimes produce tornadoes, which are violent rotating columns of air that can cause significant damage.
