Fog advisories lifted ahead of Super Bowl in New Orleans
Visibility could drop to less than a quarter-mile at times – or less during super fog – particularly in the hours before sunrise.
Super Bowl weather in New Orleans to be warm, dry
The Super Bowl is being held in New Orleans on Sunday, and despite some fog early in the morning the weather appears to be cooperating. FOX Weather Correspondent Brandy Campbell was in New Orleans on Sunday ahead of the big game and spoke with some excited fans.
NEW ORLEANS – A combination of warm temperatures, humid air and smoke from a nearby marsh fire had forecasters worried about not just foggy conditions ahead of the Super Bowl in New Orleans on Sunday but "super fog" across southeastern Louisiana ahead of the big game.
Visibility was expected to possibly drop to less than a quarter-mile at times – or less during super fog – particularly in the hours before sunrise.
The National Weather Service issued a Dense Fog Advisory for the region that has since expired, and forecasters warned that travel could be dangerous on many roads in the area.
WHAT IS SUPER FOG AND WHAT CAUSES IT?
According to the National Weather Service, "super fog" occurs when smoke and moisture from damp materials mix with cooler air, drastically reducing visibility – sometimes to less than 10 feet.
Video from FOX Weather Correspondent Brandy Campbell on Friday morning showed dense low-lying fog around New Orleans.

Fog possible culprit behind big pileup near New Orleans ahead of Super Bowl
A foggy morning near the Big Easy may have been a factor in a crash involving multiple commercial vehicles west of New Orleans on Friday.
The accident occurred in St. John the Baptist Parish on Interstate 55 at milepost 13.8, according to Louisiana State Police. That puts the crash on the western side of Lake Pontchartrain.
Officials noted that, among the vehicles involved, an 18-wheeler had overturned, forcing the closure of the southbound lanes for hours. The interstate reopened later Friday morning.
Police are still investigating the cause of the crash, but a photo from the scene shows fog in the area.

The NWS office that covers the New Orleans area reports that the record high for the date is 82 degrees, meaning temperatures will likely be closer to record warmth than to cold.
After Sunday, a storm system that will trek through the mid-South could impact travelers on their way home out of the Big Easy during the upcoming workweek.
Forecast models show wintry precipitation could fall as far south as the southern Ohio Valley and mid-Atlantic, while thunderstorms will occur along the Gulf Coast and into the Tennessee Valley.

Super fog linked to deadly crashes
Dense episodes of super fog have been linked to deadly crashes in the past, especially along Interstate 10 and the Gulf Coast.
In 2023, seven people were killed when more than 150 vehicles were involved in crashes along Interstate 55 near New Orleans.
Smoke from a nearby brush fire combined with fog to reduce visibility to near zero.
Fog blamed for crashes on Louisiana causeway
Several crashes that have been blamed on dense fog has shut down the Lake Pontchartrain Causeway in Louisiana.
In 2014, a massive pileup in Florida, along I-75 south of Gainesville, caused the deaths of nearly a dozen people when fog and smoke from controlled burns led to near-zero visibility.
The incident led to changes in protocols for when controlled burns are allowed to take place.
