Maine's first snowfall of the season lead to a swath of traffic accidents and power outages across the state Sunday.

As of 11 p.m. local time, over 143,000 customers were without power across six states in the Northeast. About 90 percent of those outages were in Maine.

According to Central Maine Power, as of 11 p.m. Sunday, about 79 percent of customers were without power in Knox County. Just over 50 percent of customers were without power in Lincoln County, down from 62 percent earlier. The utility said 79 percent of its Hancock County customers were without power.

Another 21,000 Hancock County customers were without power in Emera Maine's service area. That power company said most residents could expect power to return by the end of Wednesday, but that some remote and hard-to-reach areas may be without electricity all week.

According to the Associated Press, Maine Gov. Paul LePageissued an emergency proclamation on Sunday. The proclamation allows utility crews to spend longer hours on roads in order to help repair lines and restore power.

Central Maine Power is keeping customers updated frequently with social media. The situation was looking grim, as additional crews were called in to help repair damage:
