Over 19,000 customers across Maine lost power on Sunday, as wind gusts reached up to 50 mph in some areas during the afternoon.

The majority of outages occurred in Aroostook, Penobscot and Somerset counties, but there were 443 reported in Cumberland County, all in Yarmouth and North Yarmouth.

As of 4:26 p.m., Versant Power reported 13,268 customers without power. Penobscot County was most impacted, with 4,902 customers without electricity. Central Maine Power also reported 343 customers without power in its region of Penobscot County.

Central Maine Power reported a total of 5,821 customers without power on Sunday afternoon, with that number decreasing to around 3,500 by 8 p.m. In CMP’s service area, Somerset County had the most outages, with 1,515.

Versant Power estimated that power would be restored by 10 p.m. Sunday, according to its website; outages had declined to about 9,600 by 8 p.m. Central Maine Power did not offer an estimate for getting power back.

“We are monitoring gusty winds through today. Our crews are prepared to respond in our communities across the state,” said CMP’s Facebook page on Sunday afternoon.

Earlier Sunday, the National Weather Service’s Gray office issued a wind advisory for the state until 6 p.m. Throughout the day, northwest winds blew 20 to 30 mph with gusts up to 50 mph.

“Gusty winds will blow around unsecured objects. Tree limbs could be blown down and a few power outages may result,” said the weather service said in the advisory.

High winds also led the weather service to issue a red flag warning for fire danger along the coast and in southern Maine. The service wrote that the combination of gusty northwest winds and low humidity combined to create conditions for dangerous fire weather.

“Any fire that develops will catch and spread quickly. Outdoor burning is not recommended,” the weather service warned.
