EUREKA, Calif. – A major winter storm is set to bring heavy mountain snow, small hail and widespread rain to Northern California from Monday night through Wednesday, creating dangerous travel conditions across several key highways.
The National Weather Service in Eureka says snow levels will fall to around 2,000 to 2,500 feet Monday night and Tuesday, then drop further to between 1,000 and 2,000 feet Tuesday night. The heaviest snowfall rates are expected late Monday through Tuesday morning.
Mountain passes are expected to see significant accumulations. Forecast totals include:
- Scott Mountain Pass (Hwy 3, 5,450 ft): Around 23 inches
- Berry Summit (Hwy 299, 2,828 ft): Around 21 inches
- South Fork Mountain (Hwy 36, 4,110 ft): Around 17 inches
- Collier Tunnel (Hwy 199, 2,115 ft): Around 16 inches
- Dinsmore Area (Hwy 36, 3,000 ft): Around 14 inches
Lower elevations, including areas near Crescent City and portions of Highway 101, are expected to see little to no snow accumulation, though brief small hail is possible.
Forecasters say accumulating small hail could occur down to sea level, especially early Tuesday through Tuesday night. Hail-covered roads can quickly become slick, creating sudden “ice rink” conditions even where snow is not falling.
Widespread rain will also increase the risk of ponding on roadways and rockslides in steep terrain. Cold temperatures, downed trees and scattered power outages are possible in higher elevations.
Travelers are urged to factor weather into their plans, carry emergency supplies and monitor the latest forecasts before heading over mountain passes.
