PDS (Particularly Dangerous Situation) Severe Thunderstorm Watch In Effect for Western Maryland

The Storm Prediction Center has replaced the Tornado Watch with a PDS (Particularly Dangerous Situation) watch for portions of the area through 6:00 AM Thursday.
HAGERSTOWN, MD (WHAG) - We're still watching for the potential of severe weather overnight and into Thursday, and with that comes more weather watches for the hazards expected...



The Storm Prediction Center in Norman, Oklahoma has issued Particularly Dangerous Situation (PDS) Severe Thunderstorm Watch #302 for Garrett County, Maryland through 6:00 AM Thursday.

A PDS Severe Thunderstorm Watch means that Damaging Wind Gusts to 80 MPH are likely, several large hail events likely with a few very large hail events to 2" in diameter possible, as well as a few tornadoes.

We are watching a very large bow echo of thunderstorms that has developed out to the northwest make it's way towards the western parts of the viewing area through the overnight hours, and this has a history of producing wind damage in Northern Indiana and Northern Ohio.

This is the time to be weather aware and have an action plan together of what you and your family should do if severe weather threatens your area.

Severe Weather Watches:

A watch means conditions are right for dangerous weather. In other words, a "watch" means watch out for what the weather could do, be ready to act.

A Tornado Watch means that conditions are favorable for the development of severe weather including tornadoes, in and close to the watch area.

A Severe Thunderstorm Watch means that conditions are favorable for the development of severe weather including hail greater than 1" in diameter, and thunderstorm wind gusts above 74 MPH, in and close to the watch area.

For either kind of event, a watch means you should keep up with the weather and be ready to act.

Severe Weather Warnings:


A warning means that that the severe weather is imminent or will be occurring shortly.

A Tornado Warning means that a tornado has been detected by National Weather Service Doppler Radar or has been spotted by trained weather spotters. Take shelter immediately!

  • Move to the lowest floor of your house, such as a basement, and stay away from windows.
  • If a basement is not available, then move to the inner most portion of your house away from windows, such as a bathroom or closet. 
  • If time, take something such as a pillow, or other object to protect your head from flying debris.

A Severe Thunderstorm Warning means that a thunderstorm has been detected by National Weather Service Doppler Radar and/or one of the following severe weather reports has been received:

  • Thunderstorm wind gusts about 64 MPH
  • Hail greater than 1" in diameter (Severe thunderstorms can produce hail as big as baseballs or eggs...)
