Wind gusts up to 60 miles per hour on Wednesday night could bring down trees and power lines, warns the National Weather Service. 

A high wind watch was issued on Tuesday at 4:42 p.m. by the weather service in Taunton for much of coastal and eastern Massachusetts, including Watertown, because the south-southwest winds at 20-30 mph could gust over 40 mph, and higher in other locations.

The high wind watch means that the potential exists for strong and damaging winds in Watertown. The strong winds could bring down trees and power lines as well as cause property damage, the weather service said.

The high wind watch runs from Wednesday evening through Thursday morning.

“Unsecured outdoor objects may become damaged and/or airborne,” the weather service warned. “Hazards will be possible for motorists and pedestrians as well as to structures.”

If a high wind watch is elevated to a high wind warning, the weather service said people should stay inside and away from windows.
