San Antonio, Texas – Drivers across south central Texas are dealing with dangerously low visibility early Thursday as dense fog blankets the region, creating hazardous conditions on highways and neighborhood roads.
According to the National Weather Service office in Austin/San Antonio, a Dense Fog Advisory remains in effect until mid-morning Thursday, with visibility dropping to a quarter mile or less in spots. The advisory covers much of the Interstate 35 corridor, including San Antonio, Austin, New Braunfels, San Marcos, and surrounding Hill Country and coastal plain communities. Morning commuters along I-35, Loop 410, U.S. 281, and Highway 90 could encounter sudden visibility drops, especially before sunrise.
The fog is developing under light winds and high humidity, and officials urge drivers to slow down, use low-beam headlights, and allow extra following distance. Conditions are expected to gradually improve late Thursday morning as clouds thin and temperatures climb into the upper 70s.
Thursday night turns clearer, followed by sunny and warm conditions heading into the weekend. Looking ahead to the holiday, Christmas Eve on Wednesday is shaping up quiet and mild across the San Antonio area, with no hazardous weather expected at this time. Travelers and last-minute shoppers should see far better conditions by then, though officials recommend staying alert for any updated advisories if fog redevelops during early mornings.
