A large and potent storm system on the West Coast is already bringing very heavy snow to the northern and central California Mountains in what looks to be the most significant storm so far this season for parts of the state.
Since there is a good amount of instability in parts of the region, snowfall rates could be quite intense with locally up to 4 inches per hour possible this morning. This will make any travel in the region extremely dangerous....
The precipitation should decrease in coverage on Tuesday as the system moves deeper into the intermountain west. Locally, 4 to 6 feet of mountain snow will be possible in the northern and central California mountain range and 2 to 4 inches of rain will be possible in the California coast. Up to a foot of snow will be possible in the Southern California mountains.
