UPDATE: Tornado touches down in Revere, Mass.
REVERE, Mass. (AP) -- The National Weather Service has confirmed that a tornado touched down just north of Boston.
Revere Deputy Fire Chief Mike Viviano says the fire department in that coastal city has received dozens of calls reporting partial building and roof collapses, and downed trees and power lines.
Viviano says there are no immediate reports of deaths of serious injuries.
Another city official said many buildings sustained damage, including City Hall.
The tornado was spawned by a powerful storm that moved through the Boston area shortly after 9 a.m.
The weather service says a damage assessment is underway.
Communities across the U.S. are cleaning up after strong storms destroyed homes, knocked out power for thousands of people and toppled power lines and trees.
