Fresno, California – Drivers across California’s San Joaquin Valley are facing a high transportation risk early Monday as dense fog sharply reduces visibility, creating dangerous conditions on major highways and local roads.
According to the National Weather Service in Hanford, a Dense Fog Advisory remains in effect until 11 a.m. Monday for much of the San Joaquin Valley. Visibilities may drop to 200 feet or less in some locations, making travel especially hazardous during the morning commute. The thickest fog is impacting areas along Highway 99, Interstate 5, and routes including Highways 41, 43, 168, 180, and 198.
The fog is dense enough to cause sudden near-zero visibility, particularly in low-lying areas and near agricultural fields. Officials warn that chain-reaction crashes are a heightened concern under these conditions, especially during peak travel hours.
Motorists are urged to slow down, use low-beam headlights, and maintain extra distance between vehicles. Allowing additional travel time is strongly recommended, as delays are likely across Fresno, Bakersfield, Visalia, Hanford, and surrounding communities.
Conditions are expected to gradually improve late Monday morning as fog lifts, but localized dense patches may linger longer in some areas. Officials caution that fog events are common this time of year and additional advisories may be issued if similar conditions redevelop overnight into midweek.
