Fresno, CA – Drivers across California’s San Joaquin Valley are facing hazardous travel conditions this morning as dense fog blankets major roadways, sharply reducing visibility during the early commute hours.
According to the National Weather Service (NWS) in Hanford, a Dense Fog Advisory remains in effect for portions of the San Joaquin Valley until 11 a.m. today, following overnight fog development that intensified before sunrise. Officials warn visibility may drop to as low as 250 feet in some locations, creating a high transportation risk across the region.
The advisory impacts multiple Central California corridors, including areas near Fresno County, Kings County, Tulare County, and Kern County, with spillover effects toward the greater Central Valley metro region. Satellite imagery shows widespread fog coverage lingering longer than usual due to calm winds and saturated ground conditions.
NWS officials urge motorists to take extra precautions while traveling. Drivers are advised to slow down, use low-beam headlights or fog lights, and increase following distance to allow more reaction time. Sudden changes in visibility are possible, especially near rural highways, river crossings, and open farmland.
Traffic experts warn that fog-related slowdowns may add 10–20 minutes or more to typical commute times, particularly on Highway 99, Interstate 5, and connecting state routes. Emergency responders also caution that fog-related crashes often occur when drivers overestimate visibility or follow too closely.
Conditions are expected to gradually improve late this morning as temperatures rise and fog dissipates. Until then, commuters are encouraged to check local traffic updates and delay travel if possible.
