Sacramento, CA – A strong storm system is expected to impact Northern California from late Saturday through early Tuesday, bringing widespread rain to lower elevations and accumulating snow in the mountains.
According to the National Weather Service in Sacramento, the system will deliver moderate to heavy rain across much of the Sacramento Valley and foothills, while significant snowfall develops in the Sierra Nevada. Forecasters warn the storm could lead to longer-than-normal commutes, slick roads, and roadway flooding, especially during peak travel times.
Rainfall totals across parts of Northern California could reach several inches, with the highest amounts expected along the Sierra foothills and coastal ranges. The rain increases the risk of ponding water on roadways, localized flooding, and mud and rock slides, particularly in burn scar and steep terrain areas.
Snow levels are expected to remain above 8,000 feet on Sunday, before lowering to 7,000 to 7,500 feet Monday and Tuesday. This may lead to hazardous travel conditions across high-elevation passes, including chain controls and snow-covered roads. Motorists traveling through the Sierra are urged to monitor Caltrans QuickMap for updated road conditions.
The storm is expected to persist from Saturday evening, December 20, through Tuesday morning, December 23, with impacts varying by elevation and location.
Officials recommend residents plan for slower travel, check vehicle wiper blades, clear gutters ahead of the rain, and allow extra time to reach destinations. Drivers are also reminded to use caution during heavy rain and snow and to avoid flooded roadways.
