Heavy rain and wind expected to arrive midweek could bring flooding, power failures and mudslides in Sonoma, Lake and Mendocino counties, forecasters warned Monday.
Three back-to-back storms heading from the central Pacific toward the North Coast are "very unsettled, very wet and quite windy," said forecaster Bob Benjamin of the National Weather Service in Monterey.
"If anybody is near any flood-prone areas, they should certainly be taking precautions right now," he said.
The rains were expected to start late today or early Wednesday, with little or no break between the three storms that will swing through the region "like spokes in a wheel," he said.
As much as 7 inches of rain is expected to fall in Lake County between Wednesday and Sunday, prompting forecasters to issue a flood watch.
