A strong Pacific storm system will be moving onto the Northern California coast today. This system will bring rain and strong gusty winds as it moves through, over the next couple of days.
The strongest winds are forecast to occur late tonight through Saturday morning as the main frontal band slowly moves towards and across interior Northern California. This system will consist of a complex of more than one weather disturbance. As a result, the period of stronger winds are expected to last longer than normal.
The National Weather Service has issued a Wind Advisory for the Sierra Nevada and the Central Valley from 10 am Friday to 7 am Saturday.
Wind speeds of fifteen to twenty-five mph with gusts up to forty mph are expected in the Central Valley. Wind speeds of twenty to thirty mph with gusts up to seventy mph are expected over the Sierra Nevada.
Winds will be picking up late tonight then increase during the day on Friday. The strongest winds can be expected Friday afternoon and evening.
Some of the impacts could include downed trees and power lines, blowing debris and difficult driving conditions.
A Wind Advisory means that winds of thirty-five mph are expected. Winds this strong can make driving difficult, especially for high profile vehicles.
