Heavy rainfall, strong winds, and snow are impacting Northern and Central California, with Southern California bracing for subsequent storms later this week.

Northern California is experiencing heavy rainfall, with up to 8 inches forecast in some areas, leading to urban and small-stream flooding and saturated soils.
Wind advisories are in place across the Bay Area, with gusts reaching up to 60 mph, creating risks of power outages and downed trees.
Flood watches and warnings have been issued, particularly in low-lying areas and near rivers, with the Russian River and Green Valley Creek already reaching flood stages.
The Sierra Nevada is under winter storm warnings, with up to 6 feet of snow expected at higher elevations, creating hazardous travel conditions and avalanche risks.
