A warm storm moving into the region Wednesday is expected to bring heavy, wet snow to the Sierra and heavy rainfall, with the potential for flash floods, to Santa Rosa and other areas hit by recent wildfires.
Up to 3 feet of snow is expected to fall in the Sierra as a winter storm watch has been issued from Wednesday night through Friday morning in the Truckee area, the National Weather Service reports.
The blustery weather is expected to begin during the day Wednesday, featuring a south wind from 15 mph to 20 mph, with gusts as high as 35 mph, the weather service predicts. New precipitation amounts between a half and three-quarters of an inch are possible. The brunt of the storm will hit Wednesday night.
Rain and snow is expected to continue Thursday, turning to all snow after 10 a.m.
The National Weather Service has issued a flash flood watch for North Bay interior valleys and mountains, including areas affected by the Atlas, Tubbs, Nuns and Pocket fires as well as Santa Rosa’s Fountaingrove neighborhood. The forecast calls for 1 to 2 inches of rain for the North Bay valleys and 2 to 3 inches for the North Bay mountains. Rainfall rates could exceed a half-inch per hour, possibly resulting in flash flooding and mudslides, according to the National Weather Service.
For the Sacramento area, rain is forecast Wednesday and Thursday. There is an 80 percent chance of precipitation, bringing between a tenth of an inch and quarter of an inch of precipitation, during the day Wednesday.
