Storm Traffic: Colfax portion of I-80 closed, Stateline because of powerlines | Maps and Updates

Caltrans is also requiring chains on all vehicles without four-wheel-drive and snow tires from Nyack to Hirschdale Road in Truckee on I-80.

CALIFORNIA, USA — Rain and wind intensified early Monday morning across Northern California as many made their morning commute. 

The Monday commute was a tough one. Hundreds of Caltrans workers are standing ready ahead of flooding risks for the region. Many spinouts and crashes were reported on Highway 99 and Interstate 5 on Monday morning.

Tim Weisberg, a spokesperson for the California Office of Traffic Safety, says if people can avoid driving on the roads Monday, then they should do so. However, for people that don't have a choice, he says they should take it slow.

Stay Home if You Can

Caltrans officials are urging those who don’t need to travel or who aren’t accustomed to dangerous driving conditions to stay off the roads Monday.

“If they aren’t comfortable driving with chains, then just delay their trips. If they can Zoom and all these other online things, you can just as well conduct business virtually nowadays,” said Gilbert Mohtes-Chan, a spokesperson for Caltrans.
