A heavy rain and wind storm is forecast to drop 2 to 4 inches of rain across Connecticut, with the heaviest precipitation expected overnight Thursday into Friday morning.
The National Weather Service said the heaviest rain will fall from around 11 p.m. Thursday through 11 a.m. Friday — give or take a few hours pending any possible changes to the storm.
Winds are expected to rip across the tri-state area, causing possible damage to trees, power lines and property, the National Weather Service said. The winds are expected to hit Thursday night into Friday morning.
A high wind warning — initially issued for coastal Connecticut, Middlesex, New London, Tolland and Windham counties — has been expanded Thursday to include the entire state.
Ahead of the storm, United Illuminating issued a statement that indicated the utility company is monitoring forecasts and making preparations for the storm. The company said it will have line and tree crews on standby to restore any outages that might pop up overnight.
“While our hope is that this storm passes without impact, the weather takes no holidays, and we are ready to serve our customers 365 days a year,” said a statement from UI President Frank Reynolds.
Eversource said it will position line and tree crews across the state to respond to any outages or damages caused by the storm.
“We recognize the last thing anyone wants is another storm, especially on Christmas,” said a statement from Craig Hallstrom, president of regional electric operations for Eversource. “We’re taking all necessary actions now — including canceling employee vacations and working to secure out-of-state crews — so our team is ready to respond to whatever this storm may bring.”
There is the potential for coastal flooding between roughly 5 a.m. and 10 a.m. Friday. The weather service said the storm will bring storm conditions to coastal waters Thursday night into Friday morning, with the potential of minor coastal flooding.
The current forecasts indicate a mostly cloudy Thursday, with rain likely to start sometime in the afternoon. The rain will continue into the night, falling heavily at times, the weather service said. Temperatures will hover in the low 50s, with a high of almost 60 degrees expected.
During the day Thursday, wind gusts could reach up to 30 mph along the coast. The weather service indicated wind gusts are expected to reach up to about 65 mph Thursday night into Friday morning.
The rain is forecast to taper off before about 1 p.m. Christmas Day, with a chance of showers in some areas after that. Temperatures are expected to fall to about 42 degrees by late Friday afternoon, with a breezy wind bringing gusts up to 40 mph.
There is a “slight chance” of rain and snow showers Friday night before about 9 p.m., then a slight chance of snow showers until midnight Saturday. The temperature will drop to the low-20s, with wind chill values between 15 and 20 degrees.
