Heavy rains and strong winds are in the forecast today, prompting a flash flood watch and a wind advisory for the Riverhead area from the National Weather Service.

Rain will become heavy at times this morning with the potential for heavy downpours into early afternoon, the weather service said in a statement.

A total of 1.25 to 2.25 inches of rainfall with locally higher amounts is possible, the weather service said. Flash flooding of urban and poor drainage areas and small streams will be possible, according to the statement.

Vulnerable coastal locations along Peconic and Gardiners Bays, including Orient Point and Riverhead will likely see minor flooding, as tides will reach one to 2.5 feet above astronomical high tides.

Southwest winds of 20 to 30 mph with gusts up to 50 mph will prevail mid-morning through the afternoon, the weather service said.

Strong winds may blow down limbs, trees and power lines, causing scattered power outages, according to the National Weather Service.

Both the flash flood watch and the wind advisory remain in effect through this afternoon.

A gale warning is in effect for eastern Long Island Sound, where winds of 20 to 25 kt with gusts up to 45 kt and seas of 3 to 5 ft. are forecast.
