Blizzard Warning keeps Interstate 80 in Sierra closed for over 24 hours | UPDATES

CALIFORNIA, USA — A major winter storm with blizzard conditions pushed into the northern parts of California Friday with worsening conditions expected Saturday.

The weather forecast calls for extreme impacts in the Sierra Nevada with heavy snow and gusty winds shutting down Interstate 80 for most of Friday amid a Blizzard Warning issued by the National Weather Service. 

The NWS estimates there could be up to 10 feet of snow in areas above 5,000 feet and four feet of snow in elevations between 3,000 and 5,000 feet. Rain is expected to continue in the Valley and Foothill regions throughout the weekend.

CalTrans warned truckers not to use highways 49 and 20 as alternative routes through the Sierra. Plus, SR-89 is also closed from Emerald Bay to Bliss State Park.

Be prepared for travel delays, chain controls, and possible road closings over the weekend.
