Some of the storms could produce heavy rainfall, the agency warned, with temperatures rising to around 53 degrees by sunrise Saturday morning.

On Saturday, the rain will continue, the forecast said, though the system was expected to exit the region by mid-morning. Another quarter-inch of rain could fall during the morning hours, while winds will continue to be sustained at about 25 m.p.h., gusting to 35 m.p.h. Saturday’s high will be 53 degrees.

The NWS has also issued a coastal flood warning and a wind advisory. The coastal flood warning will be in effect from 3 a.m. Saturday to 11 a.m. Saturday, covering the morning high tide period.

“Widespread moderate tidal flooding is expected, especially along Barnegat Bay,” the warning notice said. “There is potential for some tidal gauges to reach major flood stage along Barnegat Bay. A prevailing southwest to west wind after the astronomical high tide occurs could prevent water from draining out of Barnegat Bay, which may lead to minor or moderate tidal flooding lingering into Saturday afternoon or evening.”

Roads may be impassable and damage to “vulnerable structures” could result, the warning said.
