CONCORD, Mass. (AP) — A tornado briefly touched down in the historic Massachusetts town of Concord, uprooting trees, knocking out power, and causing damage to dozens of homes.

There were no reports of injuries.

The National Weather Service after surveying the damage said that the storm that struck the town at about 3 a.m. Monday was an EF1 tornado that packed winds of about 100 mph. Weather service meteorologist Alan Dunham said the tornado caused a swath of damage about 400 yards wide and about a half-mile long.

EF1 is the second lowest of six tornado levels.

Concord fire officials say 39 homes sustained some sort of damage, but only one suffered significant structural damage. About 1,000 customers in town lost power. Downed tree limbs blocked some secondary roads.
