GRASS VALLEY, Calif. — For Tuesday's updates click HERE.


Monday's story:
A major Christmas weekend storm caused whiteout conditions and closed key highways amid blowing snow in the mountains of Northern California and Nevada.

An I-80 closure has people planted in Applegate, trying to pass the time until roads reopen. Many didn't expect how long the closure would actually take, and others didn't even know the major roadway was shut down.

"They closed the entire freeway going that way so they told us we have to go a few hours back and go all the way around. So, uh, not the best,” said Alex Task, traveling from San Francisco.

US-50 Opening Updates

Just after noon on Tuesday, Caltrans announced that US-50 has reopened after a semi-truck jackknifed on the highway caused Highway to be closed Tuesday morning.

I-80 Closure Updates

Interstate 80 remains closed as a winter storm dumps snow onto the area roadways. CHP Truckee said conditions are not good over Donner Summit and that the roadway still has no estimated time of reopening.

Caltrans echoed a similar sentiment, cautioning people who might take Rollins Lake to sneak past the closure. Officials simply said drivers will not get through.

I-80 is closed between Colfax and the Nevada Stateline.

"You will be turned around and you're putting crews at risk who are working to clear downed trees, snow, etc.," Caltrans said.

CHP Headquarters add to the calls to heed the road closures, noting that some people are trying to get around them with GPS only to become stranded on roads not designed for winter travel.
