Stray showers were expected to linger into Wednesday before sweeping south to Big Sur and the Santa Lucia mountains, according to the National Weather Service.
The skies broke open shortly after sunrise Tuesday in coastal Sonoma County and near Cloverdale, and just after 11 a.m. in San Francisco. The front arrived slightly later than anticipated, but otherwise tracked meteorologists’ forecasts with about a half an inch of rain recorded in the North Bay and between one and two inches in the region’s hills and mountain ranges.
North-blowing winds up to 30 mph gained strength and shifted direction as the front swirled overhead, but no major damage was reported. Winds were strongest in Napa, San Jose and other areas oriented on the north-south axis, meteorologists said.
Officials in Napa County urged the public to take precautions when driving in the first major rains of the year.
“We encourage people to slow down and be careful of oily pavement,” said Henry Wofford, spokesman for the Napa County sheriff’s office, which had no reports of mudslides or rain-related traffic accidents as of Tuesday afternoon.
