Update: Mother’s Day Wind And Snow In The Upper Sierra Nevada

Sponsored by:

A late season winter storm system will bring wind and snow to the mountains on Sunday.

The National Weather Service has issued a Wind Advisory for Yosemite National Park (outside of the Valley floor) on Sunday from 7 AM until 11 PM. There is also a Wind Advisory for the northern San Joaquin Valley through 8 PM Sunday. Additionally, a Winter Weather Advisory has been issued for the western slope of the northern Sierra Nevada on Sunday from 11 AM to 11 PM.

Winds of 15 to 25 mph are likely in the Central Valley with gusts up to 40 mph. West to southwest winds of 25 to 35 mph are likely in Yosemite National Park, with gusts up to 55 mph. The strongest wind gusts will be above 8,000 feet.

Total snow accumulations of four to eight inches are expected above the 5,000 foot elevation.

Gusty winds could blow around unsecured objects. Trees limbs could be blown down and a few power outages may result.

Travelers should be prepared for slippery conditions in the mountains with chain controls and travel delays. Poor visibility is possible at times in heavier snow showers. Tree branches could fall as well. People should avoid being outside in forested areas and around trees and branches.

A Winter Weather Advisory means periods of snow will cause primarily travel difficulties. Be prepared for snow covered roads and use caution while driving, especially if operating a high profile vehicle.
