Wind advisory Saturday for Washington, D.C. and Baltimore areas


Wind gust forecast at 1 p.m. Saturday indicates gusts to around 46 mph in Washington, D.C. (National Weather Service)
Winds have howled today with gusts to 35 mph, but they’ll rage tomorrow, with gusts up to 50 mph. Given the intensity of wind predicted, the National Weather Service has issued a wind advisory for the entire Washington, D.C. and Baltimore regions from 6 a.m. to 5 p.m. Saturday.

The period of strongest winds will likely fall between 11 a.m. and 4 p.m. Saturday.

The NWS cautions downed trees and powerlines will be possible from higher wind gusts. However, it has lowered its forecast for peak gusts from 60 mph (in yesterday’s high wind watch) to 50 mph.

50 mph gusts are strong, but lower than those observed during the derecho (70 mph) and Superstorm Sandy (60 mph). So power outages would tend be more isolated than during those extreme events.

Stronger winds gusting to 55 mph are possible in the mountains to the west where the wind advisory has already gone into effect. This advisory may need to be upgraded to a high wind warning Saturday the NWS said.

Locally high gusts may also be observed near the Cheseapeake Bay.

Sustained winds will generally range from 20-35 mph throughout the region.
