A late-season storm system brings the promise of significant snowfall to Northern California's mountain ranges, underscoring the region's unpredictable and powerful natural forces.Nevada City TodayThe National Weather Service has issued a winter storm watch for the Lake Tahoe area and Lassen Volcanic National Park, with forecasts calling for significant snowfall across higher elevations in several Northern California counties starting Tuesday. Travel conditions on mountain highways are expected to deteriorate, and chains or snow tires may be required.
Why it matters
Late-season storms are not uncommon in the Sierra Nevada and Cascade ranges, but the timing of this system in mid-April is a bit unusual. The snowfall could create hazardous driving conditions and impact outdoor recreation plans, requiring travelers and backcountry users to closely monitor forecasts and road reports.
The details
The winter storm watch covers areas above 3,000 feet in Tehama, Butte, Plumas, Sierra, Nevada, and Placer counties. Snowfall amounts will depend on the exact track of the system, but travel on highways like 89, roads around Lassen Volcanic National Park, and passes connecting the Central Valley to the Tahoe Basin are all likely to be affected.
- The winter storm watch is in effect from Tuesday through Wednesday.
