The advisory, which remains in effect until 9 AM CST today, warns of visibility one quarter mile or less in dense fog across the region, as reported by the National Weather Service.

Specifically impacted are the cities including but not limited to New Orleans, Metairie, Thibodaux, and Grand Isle. Motorists are advised to "slow down, use your low beam headlights, and leave plenty of distance ahead of you," according to the National Weather Service statement. This dense fog poses a serious hazard, significantly impeding one's ability to safely navigate the roads.

In addition to this morning's fog, the forecast for the New Orleans area predicts a week dotted with chances of showers and thunderstorms, coupled with temperatures steady around the mid-60s to high 70s. Today has a 30 percent chance of showers, mainly occurring before 11 AM, with patchy dense fog also expected before the same hour. These conditions are forecasted to lead into a week of fluctuating weather, presenting a mix of sunny spells and potential storms, as stated by the National Weather Service.

Tuesday and Wednesday's weather will oscillate, with a 40 and 60 percent chance of showers respectively. These showers, predicted to arrive by midday, could evolve into thunderstorms by evening. The National Weather Service foresees mostly cloudy nights, complemented by light winds that turn gustier as conditions deteriorate. Citizens are to expect potential thunderstorms later in the week, especially on Wednesday night when the chance of precipitation escalates to 90 percent.

Looking ahead, Thursday continues the trend with a 30 percent probability of showers and thunderstorms in the afternoon, while Friday offers a similar chance for rain post-noon. Into the weekend, chances of showers and thunderstorms persist, cementing a pattern of unsettled weather that characterizes the coming days.
