California – Headlights glow dimly through thick gray air as drivers inch along Valley roads this morning. Dense fog blankets the San Joaquin Valley, swallowing landmarks and cutting visibility down to just a few car lengths in places.
According to the National Weather Service in Hanford, a Dense Fog Advisory remains in effect from early morning through late morning. Visibility may drop to one-quarter mile or less, with some spots seeing as little as 200 feet. The advisory covers much of the San Joaquin Valley, including Hanford and surrounding communities.
The fog is already creating hazardous travel conditions. Major routes such as Highway 99, Interstate 5, and State Routes 41, 43, 46, 58, 59, 99, and 152 are affected. Sudden slowdowns are likely, especially near interchanges and rural stretches where fog thickens without warning.
Drivers are urged to slow down, increase following distance, and use low-beam headlights. To be fair, even familiar roads can feel disorienting when visibility collapses this quickly. Morning commuters should allow extra time and stay alert for stopped vehicles ahead.
Conditions gradually improve late this morning as sunshine breaks through and fog lifts. By afternoon, skies turn mostly sunny across Hanford, with highs climbing near 60. Clearer, warmer weather continues into Thursday and Friday, helping dry out lingering moisture in low-lying areas.
Still, winter fog remains a recurring Valley hazard. Calm winds and cool nights can allow it to redevelop overnight. Motorists heading out early should stay cautious through the end of the week.
The Dense Fog Advisory expires late this morning, but similar alerts may follow under the right conditions. If you’re driving today, what are road conditions like where you are?
