District 2 of the California Department of Transportation (Caltrans) is urging motorists to cancel travel plans ahead of a major winter storm expected to hit Northern California from Sunday (15), through Wednesday (18).
Chris Woodward, public information officer for Caltrans, described the incoming system as the most significant storm of the season for travelers and warned that road conditions could quickly become dangerous. The greatest impacts are expected along Interstate 5, where officials anticipate chain controls, traffic screenings, and the possibility of temporary closures.
Snow is forecast outside the valley in higher-elevation areas, particularly near Buckhorn Summit, Oregon Mountain, Berry Summit and Lord Ellis. These corridors are known for hazardous winter driving conditions during heavy snowfall.
Maintenance crews have been preparing in advance of the storm. Woodward said teams are conducting proactive treatments in areas prone to ice buildup. Crews typically apply brine solutions before snowfall to prevent ice from bonding to the pavement. Once snow begins falling, workers spread cinders, crushed volcanic rock, to improve traction for vehicles.
Despite those preparations, officials stress that drivers must take responsibility for their own safety. Motorists traveling through mountain areas are required to carry tire chains and should know how to install them properly. Chain checks are expected in areas such as Fawndale, where compliance is mandatory during severe weather.
Drivers are also encouraged to monitor conditions through Caltrans’ QuickMap service before heading out.
Ultimately, Woodward’s message is simple: if travel is not necessary, stay home and avoid the roads until the storm passes.
