The National Weather Service has issued a flood advisory for central Suffolk until 7:45 p.m. due to heavy rains and thunderstorms expected in the area.

Locations the service cited in its 4:51 p.m. advisory as being prone to flooding include Patchogue, Wading River, Middle Island, Manorville, Shirley, Medford, Calverton, Brookhaven National Laboratory, Yaphank, Rocky Point, Mastic, Mastic Beach, Brookhaven, Bellport, Shoreham, Carmans River, Ridge and Blue Point.

The service’s Upton office had issued an earlier coastal flood advisory for the South Shore from 6 to 10 p.m. Wednesday; southwestern Long Island is susceptible to minor coastal flooding around high tide, including the back bays of Brooklyn and portions of Queens, according to the advisory.

Rain will continue off and on the rest of the week, along with cooler than normal temperatures, forecasters said.

News 12 Long Island meteorologist Bruce Avery said the Wednesday and Thursday high temperatures, in the mid-50s, are about 8 to 10 degrees below normal for this time of the year. Clouds and rain continue into the overnight hours, and temperatures drop slightly into the mid-40s, he said.

Thursday opens with more clouds and the chance of showers again, he said.

The dreary, rainy weather continues through Friday, with Saturday warming up some, with daily highs in the mid-60s, he said.

While it’s mostly cloudy on Saturday, there should be breaks of sunshine.
