Marking the end of a stretch of dry, warmer than normal days, Tuesday is forecast to bring gusty winds and heavy rains.

A wind advisory is in effect for Long Island from 8 a.m. Tuesday to 2 a.m. Wednesday, with expectations for 20 to 30 mph southerly winds, gusting up to 45 to 50 mph.

More damaging gusts of 50 to 60 mph could also accompany any lines of heavy showers and embedded thunderstorms, the National Weather Service said in a briefing late Monday afternoon.

Forecasters were confident the area would be seeing those strong winds and some periods of heavy rain, amounting to 2 to 3 inches, and potentially 3 to 5 inches in some spots, the briefing said.

Look for the worst conditions to come Tuesday night into early Wednesday, said Bill Korbel, News 12 Long Island meteorologist.

The area is in store for some “fast-changing weather with showers, squalls and gusty winds and some very brief heavy downpours,” said Richard Von Ohlen, News 12 meteorologist.

Tuesday evening and night bring the best chances for the Island to see widespread rain, potentially heavy at times, said Joe Pollina, weather service meteorologist in Upton.

There are lesser chances for rain to start earlier, even around the morning rush hour for areas of Nassau, with rain slowly moving eastward.

Threats include the potential for downed tree limbs, isolated power outages, and minor urban and small stream flooding, along with a localized threat for flash flooding.
