NBC10.com- Glenn "Hurricane" Schwartz
Chief Meteorologist Glenn "Hurricane" Schwartz says there will be heavy rain today but the weekend will be nice and sunny.
The heaviest of the rainfall has already passed through our region, but flood warnings remain in effect as the storm will continue to pile on on to the nearly two inches of rain that already fell in parts of the Delaware Valley.
"The rain is tapering off," said NBC10 First Alert Chief Meteorologist Glenn "Hurricane" Schwartz. "It is going to end from west to east over the next six to eight hours."
Even though the worst of the storm has ended, the light rainfall will continue to drive totals up, which means flooding remains a concern, Schwartz added.
The National Weather Service issued a flood warning for urban areas and small streams in central Bucks County, as well as Delaware, Chester and New Castle counties.
The Christiana River reached 9.67 feet by noon Friday, leading the NWS to issue flood warnings for the river at Cooch's Bridge in New Castle County. Flood stage is 10.5 feet and the current forecast shows the river will rise to nearly 10.8 feet by early afternoon.
A flash flood watch began at 8 a.m. Friday and will last through the late evening for Philadelphia, Bucks, Chester, Delaware, Lehigh, Montgomery, New Castle, Gloucester, Salem and Camden counties, as well as portions of Burlington and Ocean counties, according to the NWS.
Precipitation began falling in the local region Friday morning, with totals exceeding one inch in Chester, Delaware, Montgomery and New Castle counties by noon.
Rain totals in parts of Montgomery County crept past two inches with Souderton receiving 2.5 inches and Ambler seeing 2.0 inches.
In Nottinham, Bucks County, 1.8 inches fell by 12:25 p.m. Friday, while Media, Delaware County saw 1.79 inches, according to the NWS.
Thunderstorms are also a possibility and the NWS is warning drivers that the storms will likely interfere with rush hour traffic.
The narrow system -- it stretches from Canada to the Carolinas -- already dropped at least two inches of rain in Harrisburg and about three inches in Hagerstown, Md.
The storm caused flooding in the western parts of the Keystone State. In Washington, Pa. about 20 miles southwest of Pittsburgh, nearly 30 residents were evacuated after rains heavily damaged an apartment building roof.
Conditions will improve throughout the evening, making way for a more pleasant Saturday with highs expected in the low 70s.
