Lowering Snow Levels

A cold weather system is expected to make its way into northern California bringing heavy snow Monday night and Tuesday. This will impact travel and may cause power outages. Confidence is increasing but continue to monitor the forecast at https://www.weather.gov/eka/mountainPassForecast if you intend to travel over the weekend.

Precipitation will begin to fall across Northwest California today. A very cold system will approach the area on Monday bringing lowering snow levels and an enhancement in the shower activity. Accumulating snow will become a concern on highway passes Monday night and impact all of the higher passes on 3, 36, 199, and 299 as well as possibly on highway 101 by Tuesday morning.
