Winter arrives on a drenching, windy note, as a powerful storm will be serving up bouts of heavy rain Friday, forecasters say.
Morning commuters should be prepared for “a real soaker . . . wet and windy,” said Jay Engle, National Weather Service meteorologist in Upton. Don’t be surprised to find ponding and slow traffic, he said.
And, with southwest winds gusting around 50 mph — even up to 60 mph with any isolated thunderstorm -- outdoor holiday decorations that are not well secured could take a hit, the weather service said.
A flood watch is in place for the whole region from 1 a.m. Friday to 1 a.m. Saturday, as 2 to 3 inches of rain, perhaps to 4 inches in some localized spots, leads to some flooding of low-lying and poor-drainage areas, the National Weather Service said.
That’s as rain could be falling at a rate of an inch an hour, primarily from Friday morning to afternoon.
“Flooding will likely be exacerbated in coastal locales as heavy rain coincides with the Friday morning high tide,” the weather service said.
Widespread minor to moderate coastal flooding is expected for the Friday morning high tide cycle, with a coastal flood warning in place for most of the Island’s shoreline and an advisory for Nassau’s and northwestern Suffolk’s North Shore. The Friday evening and Saturday morning high tide cycles could also bring minor coastal flooding.
Look for some waterfront road closures and widespread flooding of nearby properties, the weather service said. There could also be some dune erosion from high surf and elevated water levels.
Those gusty winds could also bring down trees and tree limbs, meaning scattered power outages are possible.
Nearly lost in the storm's drama are unusually high temperatures Friday, heading up to the low 60s.
Saturday, then, brings mostly cloudy skies and more seasonal highs in the upper 40s.
