Dense Fog Advisory Issued Across Mississippi, Louisiana, and Alabama as Visibility Drops Below One-Quarter Mile
MISSISSIPPI — A widespread Dense Fog Advisory has been issued across large portions of Mississippi, Louisiana, and Alabama, with forecasters warning that visibility has fallen to less than one-quarter mile in many areas. Drivers across the region are being urged to use extreme caution as fog spreads through major roadways, rural counties, and metro areas early this morning.
Forecast maps shared by regional meteorologists show a large shaded zone covering Jackson, New Orleans, Mobile, Birmingham, Montgomery, Dothan, Little Rock, Jonesboro, and Memphis.
Visibility Dropping Quickly Across the South
Weather analysts report that the advisory includes rapidly forming thick fog, similar to a gray-out where drivers may struggle to see mailboxes, road markings, or even nearby vehicles.
The radar map from WeatherBell Analytics highlights dense fog conditions stretching from southeast Arkansas through central Mississippi and into southern and central Alabama.
Officials say the fog is forming faster than normal due to a combination of moisture-rich air, calm winds, and lingering rainfall in nearby regions.
Hazards Expected During Morning Commutes
Forecasters warn that the current fog setup can create:
- Dangerously low visibility below 1/4 mile
- Sudden drops in visibility along highways and interstates
- Increased risk of multi-car accidents
- Slowdowns on major routes, including sections of I-10, I-20, and I-55
- Limited visibility around school zones and rural roads
Meteorologists say conditions may worsen before improving, with some areas seeing fog remain until mid-morning.
Safety Guidance for Drivers in the Advisory Zone
Authorities are urging drivers to follow key precautions:
- Slow down and allow extra stopping distance
- Increase space between vehicles
- Use low-beam headlights only (high-beams worsen glare)
- Avoid stopping in the roadway, even if visibility drops suddenly
- Watch for pedestrians and stalled vehicles hidden in fog pockets
State officials stress that fog of this density can be especially dangerous before sunrise as contrast is reduced and headlights create scatter.
Advisory Covers Multiple Southern Metro Areas
The advisory currently affects a large number of communities, including:
- Jackson, MS
- New Orleans, LA
- Mobile, AL
- Birmingham, AL
- Montgomery, AL
- Memphis, TN metro fringe
- Jonesboro and Little Rock, AR
Forecasters say additional counties may be added depending on how the fog expands over the next several hours.
Fog Expected to Lift After Sunrise, But Delays Possible
While the densest fog is expected to clear by mid- to late morning, transportation officials say drivers should expect lingering travel delays, particularly in low-lying or coastal areas where fog typically hangs on longer.
Meteorologists will continue to monitor visibility trends and update advisories if conditions worsen.
