PA Weather: Flooding Possible, Up To 3 More Inches Of Rain In Forecast

PENNSYLVANIA - A wet weekend is in store for Pennsylvania, with several inches of precipitation already drenching the state and more rain on the way, forecasters said.

While over two inches of rain have already fallen in the last 24 hours in areas like Philadelphia, Montgomery and Chester counties, up to three more inches of rain are set to fall on the state through Sunday night, the National Weather Service said.

Up to three additional inches of rain could fall in the Mount Pocono area through Sunday; the north-central region of the state could also see additional rainfall totals up to 2.4 inches in areas like Lock Haven and Williamsport, forecasters said.

The 1 to 3 additional inches of rain expected across Pennsylvania will be “mostly beneficial," but heavy downpours in a short amount of time could cause flooding on Sunday, the agency said.
