BOSTON (AP) — Strong winds are toppling power lines and trees, knocking out power to thousands of customers across southern New England.

The National Weather Service says parts of Massachusetts saw wind gusts over 50 miles per hour on Monday morning. It says the strongest winds are expected to arrive Monday afternoon in Massachusetts, Rhode Island and Connecticut.

More than 36,500 customers across Massachusetts were without power by early Monday afternoon. Eversource reported more than 8,500 outages in Connecticut. National Grid said more than 2,300 customers were without power across Rhode Island Monday afternoon.

Across southern New England, police reported fallen trees blocking roads. In Connecticut, some schools were forced to dismiss students early because of lost power.

The high wind warning for southern New England lasts until 7 p.m.
