(WVUE) - The National Weather Service has issued a dense fog advisory until 9 a.m. for southeast Louisiana and parts of coastal Mississippi.
The advisory covers the following parishes: Jefferson, Lafourche, Orleans and Plaquemines, St. Bernard, St. Charles and St. James, St. John the Baptist, Tangipahoa, Terrebonne, and St. Tammany.
The advisory also covers Hancock County in Mississippi.
The northbound and southbound sides of the bridge is down to one lane with a speed limit of 45 mph.
Dense fog will continue to be an issue, especially over water and nearby areas, through Thursday morning.
During the day, it will be unseasonably humid and warm with a stray shower or two. Highs will reach the upper 70s. Lows will only dip to the mid to upper 60s.
A cold front will finally arrive Thursday to sweep out the heat and humidity for a brief time.
Friday will feel more winter-like with highs only in the mid-50s.
It won't last long, though. A rapidly moving disturbance will return the humidity to the area on New Year's Eve.
At this time, we should be prepared for a few showers around midnight. Rain and some storms are likely on New Year's Day.
