Rain started falling in the Bay Area before sunrise Wednesday and was expected to move on by the afternoon.
The updating radar map above shows current areas of precipitation in green, with greater intensities indicated by yellow and orange.
The heaviest rain was expected in the North Bay. In areas to the south, a National Weather Service meteorologist said, it would probably top out at an inch in the Santa Cruz Mountains, half an inch in lower areas.
The more notable element of the storm was the accompanying wind, with gusts up to 55 mph predicted. A wind advisory was in effect for most of the Bay Area until 4 p.m. Wednesday.
