Wind Advisory, Outages Possible: Hudson Valley Weather

HUDSON VALLEY, NY — Get your winter hat back out. A wind advisory goes into effect Thursday afternoon as an Alberta clipper swoops through, possibly intense enough to be a bomb cyclone.

"Gusty winds generated by the strengthening storm could be strong enough to break tree limbs, which, in turn, could lead to sporadic power outages and can threaten trouble for tents and canopies set up at outdoor triage and testing centers for COVID-19," Alex Sosnowski, an AccuWeather senior meteorologist, said.

A bomb cyclone is a storm that strengthens so rapidly that the central barometric pressure plummets 0.71 of an inch of mercury or more in 24 hours, he said.

Thunderstorms will lead all along the front. Behind them — cold, cold air.

"Some major changes to the April weather pattern are on the way … which sounds about right considering we are now in spring," Alex Marra and Bill Potter of Hudson Valley Weather said.

This is the wind advisory from the National Weather Service:

• WHAT...A Wind Advisory is in effect from 2-8 p.m. Thursday. West winds 20 to 30 mph with gusts up to 45 mph expected.
• WHERE...Portions of southeast New York, northeast New Jersey, southern Connecticut.
• WHEN...From 2 p.m. this afternoon to 8 p.m. this evening.
• IMPACTS...Gusty winds could blow around unsecured objects. Tree limbs could be blown down and a few power outages may result.

There's also a flood advisory for the Long Island coast of Westchester County.

Minor flooding is expected in the most vulnerable locations near the waterfront and shoreline. Expect around 1 to 1 1/2 feet of inundation above ground level in low lying, vulnerable areas. Some roads and low lying property including parking lots, parks, lawns and homes/businesses with basements near the waterfront will experience shallow flooding.

It's going to be chilly. Here's a look at the next 48 hours:
