The National Weather Service in New Orleans has issued a Dense Fog Advisory for the region, as visibility is expected to drop to a quarter mile or less. This Advisory, which covers all of southeast Louisiana and southern Mississippi, is set to last until 10 AM CST Friday, with another Advisory in effect from 10 PM Friday to 10 AM CST Saturday.

Motorists are advised to exercise caution during these periods. Driving conditions will likely be hazardous due to the low visibility, and drivers are advised to "If driving, slow down, use your low beam headlights, and leave
plenty of distance ahead of you," as the fog blankets the area. The dense fog will be shrouding the streets in a hazard of low visibility.

The weather pattern responsible for this Advisory is characterized by patchy fog that usually lifts by mid-morning, giving way to mostly sunny skies with highs approaching the upper 70s, as reported by NWS New Orleans. However, nightly fog could potentially cause repeated disruptions to travel and other outdoor activities.

Weather forecasts for the coming days also suggest a shift, with a chance of showers and thunderstorms by Monday, followed by a drop in temperature to around 36°F on Monday night, while gusts could reach as high as 30 mph. Preparing for changeable weather, residents along the Gulf Coast should brace for a mix of sun and clouds before the temperature dips into colder territory.
