After an unseasonably warm and sunny Saturday, Long Island will be hit with a coastal storm that is expected to push through the region late Sunday, with strong winds and threats of scattered flash flooding, according to forecasters.
Saturday reached a high of 55 degrees, about 10 degrees above normal for this time of year, according to the National Weather Service. Clouds are expected to move in after midnight with a slight chance of drizzle and a low of about 43 degrees.
Sunday will not be a dry one, but it will be warm, with temperatures hitting 55 degrees. The day starts off with a light drizzle that turns to steady rain after 10 a.m.
The worst of the weather won’t come until after 1 a.m. Monday as the storm continues to gain strength while heading up the East Coast.
A high wind watch is in effect Sunday night through Monday morning, with gusts as strong as 50 to 60 mph anticipated. On Sunday, the storm is expected to dump about one-quarter to a half-inch of rain per hour, for a total of 3 inches of precipitation.
Coastal flood watches and warnings have been issued for the high tide on Monday afternoon, and there's a risk of erosion and overwashes on ocean beaches, the Weather Service said.
There is also the risk of downed trees, power lines and unsecured objects blowing away.
“If you’re putting garbage out Monday it could blow down the street. The Christmas decorations, all the decorations that sit on the lawns, like the sleds, the reindeers and the Santa Clauses might have to get taken down or properly secured,” said Jay Engle, a National Weather Service meteorologist based in Upton.
Flooding along the shore and low-lying roads could hamper travel and inundate basements and first floors of residences and businesses, according to the Weather Service.
High winds and heavy rain will continue through Monday morning with the risk of 2 to 3 feet of flooding along the coast during afternoon high tide. The flooding could lead to road closures. Temperatures will reach 58 degrees by 11 a.m., then drop to about 51 for the rest of the day. Between three-quarters and 1 inch of rain is possible.
But the good news is the storm is not expected to linger for too long.
“It starts flying out later Monday afternoon. By Monday night it will be up into southern Canada. It is going to move fairly quickly,” Engle said.
Tuesday is expected to be cooler, with a high of 43 degrees. There is also the possibility of rain before 1 p.m. but it's expected to dry out by the afternoon. Temperatures will fall to 26 degrees on Tuesday night.
Wednesday and Thursday are expected to be sunny with temperatures in the low- to mid-40s. Nights will dip to about 29 degrees.
