Rain is expected to resume by midday or early afternoon today and continue throughout the day, according to the National Weather Service.
Rain will spread over the Bay Area and as far south as the Monterey Bay area, with the heaviest precipitation in the North Bay hills.
Sonoma County will get one-quarter to three-quarters of an inch of rain, and the evening commute will be on wet roads with possible flooding due to clogged storm drains, meteorologist Diana Henderson said.
Showers will end early Tuesday, with another system expected on Wednesday, once again dropping the most rain in the North Bay, she said.
"You're going to be soggy for most of the week," Henderson said.
Santa Rosa received .02 inches of rain through 4 p.m. Sunday, and other parts of the county recorded from .01 inches in Windsor to 0.38 inches in Guerneville, according to AccuWeather.
"Although beneficial, the rain will not appreciably lower our drought status," the Weather Service said Sunday.
