Strong winds across Connecticut are being blamed for bringing down several trees and knocking out power to thousands of residents.
At the peak of the storm, there were more than 73,000 Connecticut Light and Power customers without power. As of 8 p.m., 13,838 CL&P customers were without power.
Half of Killingworth was left in the dark after a transformer caught fire on Route 81, officials said. As of 8 p.m., there were 465 customers or 16 percent without power.
It is unclear when all CL&P customers will have their power restored.
United Illuminating reported more than 27,000 outages at the peak of the storm, with the majority of them in New Haven. As of 8 p.m., there were 1,138 customers, or less than 1 percent, without power.
The majority of customers are expected to have power back by noon Friday.
"We've had crews out all morning working on this, and I'm very encouraged by the progress they're making," said James P. Torgerson, UI's president and chief executive officer in a statement Thursday. "We were ready for this storm. We'd been tracking it for a while and started making preparations for it Wednesday, well before it arrived. We understand that loss of electric service is an inconvenience for our customers, and we're working hard to get it back to everyone."
UI officials said the majority of the outages occurred after trees and limbs fell on wires and damaged equipment. Crews are focused in Bridgeport and Stratford.
Firefighters and police departments were also kept very busy, with numerous trees and power lines down across roadways.
In Durham, some power lines were brought down during the powerful storms and then caught fire. To read that story, click here.
