The National Weather Service has issued a flash flood watch and high wind advisory for all of Alameda County from Friday evening through Saturday morning, according to an AC alert Friday afternoon.

Heavy rains will total one to two inches in the valleys, two to three inches in the hills and over four inches for favored coastal slopes. Roadways are expected to flood and water will likely pond, according to the alert.

Damaging winds will also occur as the front moves through overnight into Saturday morning, according to the alert. Wind gusts from 50 to 60 miles per hour will bring down trees, branches and power lines.


There may be a brief break on Saturday morning with renewed showers and thunderstorms Saturday afternoon and evening.  Showers will linger on Sunday, but overall there will be a break in the weather.

At this time, the National Weather Service advises drivers to stay away from flooded roads.
