Sacramento, CA – Drivers across parts of Northern California are facing hazardous travel conditions this morning as dense fog redevelops across the region, impacting visibility during the busy AM commute.
According to the National Weather Service Sacramento, a Dense Fog Advisory remains in effect until 12 p.m. Friday, January 30, 2026, for the central and southern Sacramento Valley and the northern San Joaquin Valley. Forecasters say fog has become widespread, with visibility dropping below a quarter mile in many locations.
The advisory includes areas around Sacramento, Stockton, Modesto, Fairfield, and Chico, affecting commuters throughout Sacramento County, San Joaquin County, and surrounding areas. Major routes including Interstate 5, Highway 99, and Highway 50 may see sudden visibility reductions, especially during the early morning hours.
Meteorologists warn that localized visibility could fall below 800 feet, making it difficult for drivers to see stopped traffic, lane changes, or roadway hazards. The fog is expected to gradually lift late this morning as temperatures rise and winds increase.
The National Weather Service advises motorists to slow down, allow extra travel time, and increase following distance. Drivers are also urged to use low-beam headlights rather than high beams, which can reflect off fog and further reduce visibility.
Officials say conditions should improve by early afternoon, but drivers are encouraged to remain cautious until fog fully dissipates.
