Power was restored to all but a handful of Central Maine Power customers Monday after electricity was disrupted by thunderstorms late Sunday night that produced hundreds of lightning strikes and baseball-sized hail in southern and western Maine.

At their peak Sunday night, outages numbered more than 5,500 across the region, with more than 4,800 reported in York County. Hollis, a town in York County, was hit the hardest by the storms, with more than 1,200 customers without power for a time.

Margaret Curtis, a meteorologist with the National Weather Service in Gray, said the storms generated torrential rains and huge chunks of hail in some places.

The largest hailstone was recorded in Lebanon, on the New Hampshire border. Curtis said it measured 2.75 inches in diameter, or about the size of a baseball.

“York County saw the most hail, but the town of Naples was also hit hard,” she said. In Naples, hail 1.5 inches in diameter fell.
