(CNN) Cape Cod was hit by two rare tornadoes Tuesday, the National Weather Service said.

There were reports of downed trees and power lines but no known injuries, Massachusetts Emergency Management Agency spokesman Christopher Besse said.

More than 50,000 customers were without power as of 6 p.m. ET, energy company Eversource said.

Of the 1,253 tornadoes that the United States has on average each year, Massachusetts sees only one, according to the US National Oceanic and Atmospheric Administration ; only Alaska and Rhode Island average none.

Video from CNN affiliate WHDH showed extensive damage to the Cape Sands Inn in West Yarmouth. Megan McGuire, who told the affiliate that she and her mother took shelter between beds at the inn, said she'd never seen anything like it in the 24 years she's been vacationing on Cape Cod.
