Major Flooding Concerns As Coastal Storm Lingers Offshore LI

Much of Thursday turned out dry for much of Long Island as a coastal storm stayed mostly out to sea. Major flooding concerns, however, remain for parts of the South Shore.

A coastal flood warning in effect until noon for southern Nassau County and southwestern Suffolk County.

"There is a significant threat to life and property," the flood warning says. "Severe flooding will cause extensive inundation and flooding of numerous roads and buildings."

The National Weather Service says: "The greatest threat for moderate to locally major flooding exists across the South Shore back bays of western Long Island, with a more localized threat across the eastern bays, including the north-facing shorelines of the forks of Long Island. Tidal departures of 2.5 to 3.5-feet above normal are expected during this period."

High tide is at 9 p.m. Thursday and 9 a.m. Friday in Lindenhurst. In Freeport, high tide is at 7 p.m. and 7 a.m.

A coastal flood advisory is in effect for the rest of the island from 9 p.m. Thursday until 1 p.m Friday. A wind advisory is also in effect overnight for Suffolk County where 50 mph gusts are possible.
