Winter Storm Watch Above 8,000 Feet

A tropical moisture plume over the Pacific Ocean is moving onshore today in Northern California and is expected to bring two waves of wet weather to the region: This evening into Saturday and Sunday into Monday.

Precipitation amounts in the valley Thursday through Saturday are expected to range around an inch.

Total rainfall amounts for most of the Central Valley through Monday will range from one to five inches, with five to ten inches expected across the foothills and the Sierra Nevada.

Some of the impacts could be localized urban and small stream flooding and occasional power outages from breezy and gusty winds. There is also the potential for debris flows near wildfire burn scars.

Snow levels will generally remain above 7000 feet through the weekend but sometimes will lower, especially on Friday.

The National Weather Service has issued a Winter Storm Watch for the Sierra Nevada above 8000 feet, which is in effect from Friday afternoon through Saturday afternoon.

Snow accumulation of eight to twelve inches is expected above 8000 feet, with up to eighteen inches near the crest.

The heaviest snow is likely from late Friday night through Saturday morning. Snow will diminish during the day Saturday.

Additionally, a Wind Advisory has been issued for both the Sierra Nevada and the Central Valley from 10 am Friday to 7 am Saturday.

Wind speeds of twenty to forty-five mph with gusts up to seventy-five mph are forecast over the Sierra Nevada. Wind speeds of fifteen to twenty-five mph with gusts up to forty-five mph are expected in the Central Valley.

Winds will be picking up late tonight then increase during the day on Friday. The strongest winds can be expected Friday afternoon and evening.

Some of the impacts could include downed trees and power lines, blowing debris and difficult driving conditions.
