Snow elevations will possibly drop to the 4,000-foot level which will affect all mountain regions in Riverside and San Bernardino counties, including the Cajon Pass and Mountain Pass on Interstate 15 (I-15). Road conditions will be icy in areas that are affected by snow.
Caltrans maintenance crews are preparing state highways for rain and snow. The mountain and pass regions will be preparing the highway in advance of the storm with deicing agents. Snow plows and other equipment are ready, and staff will be working 24/7 during the storm event.
Motorists are advised to avoid travel during storm events and to SLOW DOWN! Chains will be required in mountain areas. Remember to bring chains even if it not snowing due to sudden weather changes.
