First rain of wet season dumps an inch to some parts of Bay Area

The first storm of the wet season Tuesday dumped nearly an inch of rain on parts of the Bay Area, making roads especially slick for early morning commuters.

Parts of the North Bay — Petaluma, Santa Rosa and Sebastopol — were doused with nearly an inch of rain, according to the National Weather Service.

San Francisco had received close to a tenth of inch by about 7 a.m., but the main “precipitation band” of the storm hadn’t yet swept into the city, said Drew Peterson, a meteorologist with the National Weather Service.

By about 9 a.m., the showers should strengthen over the city, he added.

This is the first measurable rainfall in San Francisco since June 9, when .01 inches were reported.
