Louisiana drivers are creeping through thick, low-hanging fog across New Orleans this morning, with headlights glowing in a gray haze. Visibility has dropped to a quarter mile or less in spots, especially along Lake Pontchartrain and elevated stretches of I-10. Brake lights are appearing suddenly out of the mist.
According to the National Weather Service in New Orleans, a Dense Fog Advisory remains in effect until 8 a.m. for southeast Louisiana and southern Mississippi. Calm winds and high humidity have allowed fog to thicken before sunrise. Forecasters warn that low visibility could make driving conditions hazardous through the early commute.
Slow down immediately if you encounter dense fog. Use low-beam headlights and leave extra space between vehicles. Conditions can change block by block, particularly near bridges, waterways, and low-lying areas.
Fog gradually lifts later this morning, giving way to partial sunshine and a warm afternoon high near 75 degrees. Patchy fog may redevelop late tonight into early Thursday, with lows near 57.
The broader February pattern stays mild. Highs reach near 70 Thursday and 71 Friday under partly sunny skies. Valentine’s Weekend turns more unsettled. A 40 percent chance of showers develops Saturday afternoon, with breezy conditions and highs near 75. Showers and possible thunderstorms become more likely Saturday night into Sunday before gradual clearing.
Early next week trends warmer, with highs pushing the upper 60s to near 70 and long-range signals pointing to above-average temperatures continuing across the Gulf Coast.
