'Superfog' Causes Traffic Chaos as Louisiana Battles Marsh Fire and Flooding

A "superfog" caused by a combination of dense fog and smoke from marsh fires led to numerous traffic accidents, including multi-car pileups, in southeast Louisiana. Sections of Interstates 55 and 10 remained closed, and the causeway over Lake Pontchartrain was intermittently shut down. The National Weather Service attributed the "superfog" to the mixture of smoke and fog, with visibility expected to improve as the fog lifted. The duration of the marsh fires and their impact on visibility remains uncertain, leading to class cancellations and delayed openings for several schools in the area.
