Strong winds began blowing across the Tri-Valley this morning as a wind advisory was issued by the National Weather Service for much of the region that will be in effect until Monday morning.
Developing shortly after sunrise this morning, the strong northerly winds are expected to sweep across the East Bay Hills and Mount Diablo State Park, where the weather forecast is predicting gusts will reach speeds up to 60 mph at higher elevations.
With the potential to down trees and disrupt power in the region, the strongest winds are forecast for tonight and Sunday night. Sustained north to northeast winds of 20 to 40 mph are expected at elevations above 2,000 feet.
Areas around Mount Diablo and the East Bay Regional Park District are expected to be hit hardest by sustained winds and a prolonged wind event, according to the weather service.
The advisory is in effect from 7 a.m. today until 10 a.m. Monday and impacts Alameda, San Benito, Contra Costa, Marin, Monterey, Napa, San Francisco, San Mateo, Santa Clara, Santa Cruz, and Sonoma counties.
The National Weather Service is advising residents to take precaution when using backyard barbecues and suggests securing outdoor furniture.
Motorists are also advised to drive with care because the strong winds are expected to make driving more difficult, according to the weather service.
Even with the winds, Pleasanton and the Tri-Valley are expected to be sunny and warm today, with a high of 71 degrees. Tonight, the area is expected to be clear, with lows in the mid 50s and northwest winds of 5 to 15 mph anticipated.
