Tornado Watches Issued Across Eastern PA With Severe Storms Forecast: See Latest

PENNSYLVANIA — Tornado watches have been issued for much of southeastern Pennsylvania until 11 p.m. as severe weather is expected through Monday evening, according to the National Weather Service.

The watch includes much of eastern Pennsylvania including Philadelphia, Bucks County, Chester County, Delaware County, and Montgomery County, the National Weather Service said.

"Widespread gusts" of wind up to 75 miles per hour and isolated hail up to the size of a ping-pong ball are both possible, added the NWS.

Monday is slated to kick off several rounds of wet weather in the Keystone State this week, as severe thunderstorms bring the possibility of heavy rain and flash flooding, as well as a possible tornado.

The most severe storms are expected between 4 and 10 p.m., and will move from west to east, the National Weather Service said.

Numerous severe storms are possible in the Philadelphia region, with some areas of south central Pennsylvania at the risk of "widespread severe storms" and damaging winds, said the NWS. This includes Lancaster and some communities south of Harrisburg.

“The primary threat will be damaging winds with a couple tornadoes possible. Flash flooding remains a threat as well,” the National Weather Service Mount Holly Station said in a statement. “Please ensure you have multiple ways to receive warnings and remain weather aware on Monday.”

The Pittsburgh metro area is also at a slight risk of severe weather on Monday, forecasters added.
