Understanding Pennsylvania Severe Thunderstorm Watches and Warnings

What is a Severe Thunderstorm Watch?

A Severe Thunderstorm Watch means conditions are favorable for severe thunderstorms to develop in and near the specified area. This is not a warning; it's an alert that the potential exists. Severe thunderstorms are defined as those containing winds of 58 mph or greater, hail 1 inch in diameter or larger, or a tornado. A watch might be issued due to factors like:

Instability in the atmosphere (high temperatures and humidity)
Strong wind shear (changes in wind speed and direction with height)
Approaching frontal systems
The presence of a significant upper-level disturbance

Think of a watch as a heads-up; it’s time to monitor the weather closely and prepare.

What is a Severe Thunderstorm Warning?

A Severe Thunderstorm Warning means a severe thunderstorm is happening now or is imminent. This is a serious alert requiring immediate action. Severe thunderstorms pose significant dangers, including:

High Winds: Capable of downing trees and power lines.
Large Hail: Can damage property and injure people.
Tornadoes: Extremely dangerous rotating columns of air.

When a warning is issued, you must take immediate shelter. Don't wait!

Staying Safe Outdoors

If you're caught outdoors during a Severe Thunderstorm Watch:

Seek Shelter: Immediately find a sturdy building or vehicle.
Avoid Tall Objects: Stay away from tall trees, isolated sheds, and power lines.
Lightning Safety: If you hear thunder, immediately seek shelter. Remember the 30/30 rule: If you can hear thunder 30 seconds after a lightning flash, it is considered close enough that you should take shelter. Stay indoors at least 30 minutes after the last clap of thunder.
Monitor Weather Updates: Stay informed about the storm's progress via weather radio or your phone.

Protecting your property from severe weather involves:

Vehicle Protection: Park vehicles in garages or under cover.
Insurance Coverage: Ensure you have adequate homeowners or renters insurance.
