Some strong, gusty winds and heavy rain are in the works, most likely in the Sunday night to Monday night range, as a strengthening storm packed with tropical moisture is to travel up the coast this weekend, forecasters say.

The system also brings the potential for minor to locally moderate coastal flooding, the National Weather Service said.

Sunday brings a chance of rain, but also the likelihood for “strong easterly winds” from Sunday night through Monday night, and possibly into Tuesday morning, according to a hazardous outlook the weather service issued for Long Island.

Sustained winds of 25 to 35 mph are possible, with gusts up to 50 mph, for Sunday night into Monday night, said Carlie Buccola, weather service meteorologist based in Upton. Still, she said, such specifics are subject to change.

The heaviest rain, she said, is expected for the Monday afternoon to evening hours, at least as of Friday afternoon’s forecast. In all, the area could see 1 to 3 inches of rain, with locally higher amounts possible, from late Sunday into Tuesday.

Still, uncertainty as to the storm’s track and timing “can affect the rainfall timing and amount,” she said.

Plan on Monday being “a windy and wet day,” she said, with resulting reduced visibility meaning drivers should take special care. There’s also potential for tree damage and power outages, she said.

All this also brings the chance for minor to moderate coastal flooding during Monday and Tuesday mornings’ high tide cycles, she said, pointing to “flood prone locales” around the South Shore bays, eastern bays and the western Long Island Sound.

Rain, not snow, is in the picture for Long Island thanks to continuing above-normal temperatures, said Rich Hoffman, News 12 Long Island meteorologist.

High temperatures Saturday are expected to be near 50 and in the mid- to upper 40s on Sunday.
