Houston, Texas – A widespread dense fog event is creating hazardous travel conditions this morning across a large swath of the southern United States, stretching from the Gulf Coast into the Mid-South, with visibility dropping to a quarter mile or less in many areas during peak commute hours.
According to the National Weather Service, Dense Fog Advisories are in effect across much of southeast and south-central Texas, including Houston, Galveston, College Station, and the Brazos Valley, extending north and east through Louisiana, Arkansas, Mississippi, and into western and middle Tennessee. Visibility has been sharply reduced along major corridors including Interstate 10, Interstate 45, Interstate 55, Interstate 40, and Interstate 65, making early morning driving especially dangerous.
The fog is also impacting coastal and marine areas along the upper Texas Coast and Gulf waters, where navigation has become difficult in and around Galveston Bay and Matagorda Bay. Farther inland, dense fog has settled across Memphis, Jackson, Nashville, and surrounding communities, contributing to slow-moving traffic and an increased risk of accidents.
In some northern portions of the region, including parts of the Mid-South, freezing temperatures may allow fog to deposit a thin glaze on bridges and overpasses, creating isolated slick spots.
Drivers are urged to slow down, use low-beam headlights, and increase following distance. The fog is expected to gradually lift from south to north later this morning, but advisories remain in effect through mid to late morning, and additional updates may follow as conditions evolve.
