California is catching a brief breath this Friday, but the respite won’t last long. Just days after a massive winter storm buried the Sierra Nevada and drenched the lowlands, weather models show another powerful system queuing up in the Pacific.
This next round of weather is expected to move onshore late Sunday, threatening to pile even more snow onto a region already struggling with road closures and avalanche risks.
The numbers coming out of the mountains this week are staggering. According to the Central Sierra Snow Lab, over 92 inches of snow fell in just the last seven days. Some northern and central parts of the Sierra Nevada saw nearly eight feet of accumulation before the most recent Thursday storm even began.
While these totals aren’t record-breaking for the high-altitude range, the sheer volume has created dangerous conditions. Interstate 80 and the Donner Pass area have faced repeated closures as road crews scramble to clear paths, and local officials have reported multiple deadly avalanches in the backcountry.
A narrow window for cleanup exists between now and Sunday morning. Caltrans and local utility workers have about 48 to 72 hours of relatively dry weather to dig out before the next system arrives. This upcoming storm is forecast to spin slowly toward the coast, starting first in the northwestern corner of the state and coastal Oregon before pushing southward.
The severity of this next hit depends on the behavior of an atmospheric river—a long plume of moisture stretching across the Pacific. If this “river” stalls over Northern California, mountain peaks could see several more feet of fresh powder, while lower elevations face drenching rains. Current projections suggest the heaviest impacts will stay focused on the northern half of the state rather than Southern California.
Despite the travel headaches and safety hazards, the relentless weather is a win for the state’s water security. The Sierra Nevada snowpack acts as a frozen reservoir that feeds California’s rivers and streams during the dry summer months.
Because of a wet 2025 and the steady barrage of storms this year, California remains entirely drought-free. Experts note that while surface soil will likely dry out during the 2026 autumn heat, the state’s overall water supply is in a very strong position for the foreseeable future.
