Super fog covers St. James Parish and parts of southern Louisiana
‘Super fog’ covered St. James Parish and parts of southern Louisiana on the morning of Friday, November 14, 2025. Near-whiteout conditions were reported on some roads, while visibility was reduced to 3 m (10 feet) in multiple areas.
The super fog was caused by the mixing of smoke from cane burning with the naturally dense fog of the region. The contributing wildfires are small and are located in St. James, St. John, and Lafourche Parishes. While not unusual at this time of year, the dense fog creates dangerous travel conditions due to reduced visibility.
The National Weather Service (NWS) New Orleans issued a dense fog advisory earlier on Friday, with super fog reports coming in from local officials on local highways, which were shut down for the Friday morning commute.
More fog is possible this weekend and the start of next week as temperatures continue to rise.
Patchy fog may develop Saturday morning. Areas near controlled burns or marsh fires may experience super fog, which is an extremely thick fog that creates zero visibility. Cities that could see super fog include LaPlace, Baton Rouge, Gonzales and Donaldsonville.
November is one of the foggiest months of the year in the Gulf Coast area, with portions of the Louisiana coast averaging about 35–40 days a year with heavy fog.
