Early risers in Jacksonville and surrounding areas were met with a blanket of dense fog. The National Weather Service in Jacksonville issued a Dense Fog Advisory that remained in effect until 9 AM EST this morning. According to the advisory, visibility was reduced to one-quarter mile or less, presenting potentially hazardous conditions for drivers.

Residents across various parts of northeast Florida and southeast Georgia found their visibility constrained to a mere fraction of what is typically expected. Areas affected included Inland Nassau, Coastal Nassau, Coastal Duval, Trout River, and more. The fog was thick enough to prompt authorities to advise drivers to "slow down, use your headlights, and leave plenty of distance ahead of you," according to the NWS website.

The NWS forecast didn't let the fog cast a shadow on the rest of the day's weather prospects. After 9 AM, the Jacksonville area can expect an otherwise sunny day with a pleasant high of around 69 degrees. The calm morning winds were expected to pick up slightly, coming in from the northeast at 5 to 8 mph in the afternoon. Tonight's forecast predicts mostly clear skies with a low around 51 degrees, and a northeast wind 5 to 11 mph, and gusts that could reach as high as 16 mph.

Jacksonville residents can look forward to a string of mostly sunny days, with highs consistently near the mid-70s and lows in the mid-50s. From the mostly sunny skies predicted for Monday to the sunny outlook for Christmas Day, the forecast from the NWS brings a bright note to the holiday preparations.
