Winds close to hurricane strength swept across parts of the northeastern U.S. on Wednesday morning, toppling trees, taking down power lines and leaving tens of thousands of residents without power.

The National Weather Service reported that winds gusted as high as 72 mph near Boston at around 7 a.m. before leveling off through the morning.

Power lines were reported down across the region, with the worst damage reported in southern New England.

Rhode Island and Connecticut each had more than 20,000 customers without power, leading some schools to move classes online or cancel them entirely.

Toppled trees snarled traffic in parts of Massachusetts, including in Boston, where a large tree blocked the exit ramp from busy Storrow Drive to Massachusetts General Hospital.

State Police said on Twitter that the ramp would be closed for an “extended period of time” while a contractor was called in to remove the tree.

Fire officials in Plympton, Mass., said firefighters responded to calls for trees and wires down or on fire. In one case, a tree landed on a car with adults and children in it, the fire department said on Twitter. No injuries were reported.
