Jackson, MS – — Dense Fog Advisory is impacting northeast Louisiana and much of Mississippi this morning, with visibility dropping to one-quarter mile or less through 9 a.m. CST Saturday. The National Weather Service (NWS) in Jackson has warned that the early-morning commute may become dangerous due to rapidly changing visibility and thick patches of fog across major travel routes.
Overview of the Fog Event
Much of the region woke up to a blanket of dense fog that formed quickly overnight. According to the National Weather Service, calm winds combined with high ground moisture after recent weather activity created ideal conditions for widespread fog formation across several counties and parishes.
The advisory extends across Madison, Franklin, Catahoula, Tensas and Concordia parishes in Louisiana, and a broad section of Mississippi, impacting cities such as Jackson, Vicksburg, Meridian, Columbus, Starkville, Pearl, Ridgeland, Hattiesburg, Laurel, Natchez, Brookhaven, Forest, Philadelphia, Yazoo City and McComb.
Timeline of Events
Fog began developing late Friday night and thickened rapidly before sunrise. By early morning, visibility had already deteriorated to below a quarter mile along several major interstates and rural roadways. The advisory remains active until 9 a.m. CST, though meteorologists expect some fog pockets to linger as temperatures rise.

Drivers traveling early this morning should anticipate sudden visibility drops on key highways. Roads most affected include:
- I-20
- I-55
- US-49
- US-61
- MS-25
- MS-35
Low-lying areas near major rivers—such as the Pearl River and the lower Mississippi River—are experiencing some of the densest fog. Open farmland, shaded roadways, and wooded sections are also reporting extremely poor visibility.
