Dense Morning Fog Spreads From Texas to Florida as Gulf Moisture Surges Into the Southeast Ahead of Next Front
SOUTHEASTERN UNITED STATES — A widespread fog event is unfolding across much of the southern and southeastern U.S. Wednesday morning as deep Gulf moisture continues wrapping northward, creating reduced visibility from Texas through Louisiana, Mississippi, Alabama, Georgia, and into Florida.
The current morning map shows fog alerts covering a broad corridor along the Gulf Coast and inland portions of the Southeast, with conditions expected to remain problematic during the early commute.
Gulf Moisture Driving Repeated Fog Development
Meteorologists indicate the fog is being fueled by persistent low-level moisture flowing north from the Gulf of Mexico, combined with light winds and mild overnight temperatures. This setup is allowing fog to redevelop night after night, especially in west-central Florida, which has been placed in what forecasters describe as “repeat mode” for fog formation.
The pattern is not expected to break quickly. Similar conditions are likely to return Thursday and Friday mornings, particularly across Florida and parts of the Deep South.
Reduced Visibility a Concern for Morning Travel
With fog becoming dense in spots, drivers may encounter sudden drops in visibility, especially along coastal areas, low-lying regions, and rural highways. While the fog is expected to thin as temperatures rise later in the morning, early travel will require extra caution.
Forecasters note that high-resolution models, including the HRRR, accurately captured the fog development overnight, reinforcing confidence that additional fog events are likely before the next cold front arrives.
Warmer Air Building Ahead of the Next Front
Ahead of the approaching front, heat and humidity will continue building across the Southeast, further supporting fog formation during overnight and early morning hours. Once the front moves through later this week, conditions may finally begin to change, but until then, fog remains a daily concern.
Residents across affected states are encouraged to slow down during morning travel, use low-beam headlights in fog, and remain alert for changing road conditions.
