YARMOUTH, MASS. (WHDH) - Tens of thousands of people are without power after the National Weather Service says a tornado touched down in South Yarmouth on Tuesday.

The weather service and the state Emergency Management Agency went to the scene for further assessment.

Wind gusts of more than 90 mph in some areas uprooted trees, ripped off roofs, sent sheds airborne, blew down fences, and toppled utility poles.

The storm system also produced thunder, hail, lightning, and heavy downpours.

More than 50,000 Bay State residents were without power at 4 p.m., according to the Massachusetts Emergency Management Agency.

Chatham, Dennis, and Harwich appeared to be the hardest-hit areas.

Police in those towns warned residents to stay in their homes due to extensive damage from downed wires and trees that have made roads impassable.

Strong storms off the coast of Cape Cod just west of Martha’s Vineyard produced a waterspout before the tornado touched down, according to forecasters.

“We’ve seen some spin and rotation to the east of Block Island,” 7Weather meteorologist Chris Lambert said. “The cell likely has produced a waterspout south of Rhode Island.”

No information on the tornado’s strength was released but crews are working to determine if a second tornado touched down.
