Most of Connecticut is under a High Wind Warning until 6 p.m. Thursday.

The National Weather Service says west winds will be blowing 20 to 30 mph with gusts up to 65 mph.

“Damaging winds will blow down trees and power lines. Widespread power outages are expected. Travel will be difficult, especially for high profile vehicles.”

More than 40,000 Connecticut customers lost power Thursday.morning.

A High Wind Warning means a hazardous high wind event is expectedor occurring. Sustained wind speeds of at least 40 mph or gustsof 58 mph or more can lead to property damage.

High pressure will slowly build in from the west as the coastal low moves into the Canadian Maritimes.

Winds will begin to diminish Thursday night, but still remain breezy with gusts ranging between 25 and 30 mph, with the strongest winds along the coast.

AccuWeather said as the storm underwent rapid strengthening, it unleashed drenching rain, hurricane-force winds and even some high-elevation snow to the northeastern United States.

The storm strengthened at a fast enough pace into Thursday to be classified as a bomb cyclone. For a storm to meet bomb cyclone criteria, the barometric pressure has to fall at least 24 millibars, or 0.71 of an inch of Mercury, in 24 hours.

On Wednesday, AccuWeather meteorologist Jesse Ferrell predicated that this storm may allow new pressure records to fall. At least one weather record was broken as areas when Providence, Rhode Island, set a new monthly record reaching 976.3 mb at 3:54 a.m. Thursday. October records were also set in Boston and Concord, New Hampshire.
