NORTH BERWICK (AP) – The National Weather Service, after surveying damage, confirmed Saturday that a storm that damaged several buildings and downed trees Friday was a low-level tornado.

The intensity of the tornado was classified as a strong F1 on the Fujita scale, with maximum winds on touchdown estimated at between 100 and 110 miles per hour, according to John Jensenius of the weather service office in Gray.

“In terms of the overall scale, it is a relatively low tornado,” he said. The weather service said Maine averages about two tornadoes a year. “Fortunately, we don’t have the stronger categories here,” Jensenius said.

The weather service said a path of damage extended for more than a mile, with a maximum width of about 200 yards.
