Southern California Mountains Battling Blizzard-Like Conditions, Highway 18 Impacted
A powerful winter storm is unleashing blizzard-like conditions across the mountains of Southern California, creating hazardous travel conditions and prompting chain controls. Highway 18, a key route into Big Bear Lake, is particularly affected, with drivers reporting near-zero visibility at times.
Highway 18: A Critical Artery in Winter Weather
State Route 18 serves as a primary access point to the San Bernardino Mountains, connecting communities like San Bernardino, Big Bear Lake and Llano. According to the California Department of Transportation (Caltrans), as of Monday, February 16th, 2026, chain requirements are in effect for all vehicles except four-wheel-drive vehicles with snow tires on all four wheels from the junction of SR 189 to one mile north of Ranch Road in San Bernardino County.
Recent reports indicate that snowplows are actively working to preserve Highway 18 passable, but conditions are rapidly deteriorating. Drivers traveling from Highland have experienced extremely limited visibility, necessitating the employ of tire chains or four-wheel drive.

The storm’s early arrival caught some travelers by surprise. One driver, Stephen, traveling from San Diego, noted the storm arrived sooner than anticipated. Despite the challenging conditions, some visitors remain optimistic, embracing the opportunity for winter recreation.
While the snowfall is expected to benefit ski resorts, some visitors have already cut their trips short due to the intensity of the storm. One skier at Snow Valley Resort stated they were only able to complete three runs before deciding to head home due to the poor visibility.
