A major coastal storm is forecast to bear down on the New York metro region late tonight into Monday, bringing potentially heavy rainfall, high winds and widespread minor to moderate coastal flooding across the area, according to the National Weather Service.
High wind and coastal flood warnings have been issued for eastern Suffolk County, from late tonight through Monday.
Southeast winds of 25 to 35 mph with gusts up to 60 mph are expected, the weather service said. The strongest winds are expected to occur after 2 a.m. Monday, according to the forecast.
A high wind warning is in effect from midnight tonight to noon on Monday.
Rainfall of 2 to 3 inches is expected, with local amounts of 4 inches possible, according to the NWS forecast.
Widespread moderate flooding is likely, and locally major flooding possible, with the Monday afternoon high tide, the weather service said. Coastal flooding with 1 ½ to 2 ½ feet of inundation above ground level is expected at the Monday afternoon high tide cycle, at about 4 p.m. Monday on the Peconic River in downtown Riverhead, the weather service said in a statement. The tide will be about 3 ½ to 4 feet above normal.
The parking lot along the Peconic River will likely flood tomorrow afternoon during high tide, Riverhead Police said in an advisory this morning. Police urge residents to move their vehicles out of the parking lot to higher ground north of Main Street.
A coastal flood warning is in effect from 11 p.m. tonight until 6 p.m. Monday.
Breaking surf of 12 to 16 feet, causing widespread dune erosion and scattered overwashes, are likely for the ocean beachfront along the south shore.
Storm conditions are likely on all waters Sunday night through Monday, the weather service said.
Temperatures will remain unseasonably warm today and tomorrow, with a high today of 56ºF and Monday’s high reaching about 60ºF.
The precise track of the storm remains uncertain as of Sunday morning, forecasters at the National Weather Service in Upton said in a forecast discussion statement issued early this morning.
“Models are still trying to resolve where the center of this storm will be by the time it gets near us,” the National Weather Service in Upton said in The forecast models are “depicting a broad storm center with two separate circulations,” according to the statement. “There’s at least agreement that the northern circulation will likely pass through the western half of the forecast area Monday morning, with the southern circulation moving through the eastern half of the forecast area Monday afternoon as it tries to merge with the other. This will maintain the likelihood of rain into Monday afternoon for most spots.”
