Coastal flooding and pounding surf are the main concerns at the Jersey Shore as a weakening Hurricane Dorian hammers the Outer Banks of North Carolina before heading out to sea.

Meanwhile, scattered showers are expected in the immediate Philadelphia area as Dorian’s outer rings extend over region.

A coastal flood advisory has been issued for Atlantic, Cape May, and Cumberland Counties in New Jersey and along the entire Delaware coast starting at 1 p.m. Friday

The National Weather Service says the main threat of flooding will be during high tide, which is expected to occur between 2 p.m. and 3 p.m. along the oceanfront and later in the back bays and on Delaware Bay.

A high surf advisory remains in effect along beaches for six- to 10-foot breaking waves and strong rip currents that pose a life-threatening danger to anyone entering the surf.

A maritime tropical storm warning is in effect for coastal waters south of Great Egg Inlet at Ocean City for high winds and seas four to six feet, building to nine to 14 feet before gradually subsiding later Friday night.

A half-inch to nearly an inch of rain is possible at the Shore, the weather service says.

It will be breezy, with a northeast wind of 17 to 23 mph and gusts as high as 37 mph at the Shore.

In Philadelphia, scattered showers are expected after 10 a.m. with less than a tenth of an inch of rain possible. Otherwise it will be cloudy with a high temperature near 72 degrees.

Winds will be from the northeast in the 9-to-16 mph range, with gusts as high as 28 mph.

Dorian is expected to be about 200 miles out to sea when it reaches the New Jersey coast later Friday and be north of the area by Saturday morning.

On Saturday, it will be mostly sunny with a high in the upper 70s in Philadelphia and at the Shore.
