A severe thunderstorm warning has been announced for 10 Pennsylvania counties, including the Philadelphia area. The National Weather Service has issued the severe thunderstorm warning for Bucks, Chester, Delaware, Montgomery and Philadelphia counties through 8 p.m. Monday.

In addition to the severe thunderstorm warning, a flash flood watch is in place.

Bad storms are expected in the area this afternoon. The Weather Channel predicts they'll arrive around 3 p.m. and be strongest around 4 p.m., according to the latest hourly forecast.

"Damaging wind gusts and hail are the primary concerns, although an isolated tornado can't be ruled out. This may include swaths of concentrated wind damage in the Northeast that lead to tree damage and power outages. Heavy rain may cause flash flooding in some areas," the Weather Channel said.
