Drivers are urged to use caution this Halloween weekend as super fog is expected to return.
The National Weather Service advises drivers to avoid driving overnight and in the early morning on Saturday.
A dense fog mixed with smoke from nearby marsh fires provided challenging visibility for drivers Monday, which resulted in a pileup of 158 cars on I-55 between Ponchatoula and LaPlace.
The pileup has killed eight people, but that number is expected to increase.
The dense fog advisory was from 10 p.m. Friday to 9 a.m. Saturday. Fog is possible on Sunday. It covers New Orleans, Baton Rouge, Hammond, and Slidell areas. It also includes portions of southern Mississippi.
Forecasters say fog near and downstream of the marsh fires could make driving dangerous, especially between New Orleans and Baton Rouge, as well as the Northshore of Lake Pontchartrain. The super fog could be thickest in areas near water, such as the Causeway Bridge and portions of I-55.
- Turn on low beam headlights, even if it is daytime
- Drive slowly and leave plenty of space between you and other vehicles.
- Consider delaying travel if a dense fog advisory is issued, if possible.
