JACKSON, MS – A Dense Fog Advisory has been issued for areas south of Interstate 20 in Mississippi, with dangerously low visibility expected between 3:00 A.M. and 9:00 A.M. on Wednesday, March 26. The National Weather Service (NWS) in Jackson warns that fog could become so thick in some areas that visibility may drop to one-quarter mile or less, creating treacherous driving conditions during the early morning commute.
Which Areas Will Be Affected?
The advisory primarily covers locations south of I-20, with the most severe conditions expected along and near the Highway 84 corridor. Cities such as Hattiesburg, Brookhaven, McComb, and Meridian could see significant fog buildup, making travel dangerous and unpredictable.
What Drivers Need to Know
Dense fog creates an invisible threat on the roads, reducing visibility and reaction times for drivers. Traffic accidents increase dramatically during foggy conditions, often due to speeding or failure to adjust driving habits.
If you must drive during this period, take extreme caution and follow these NWS-recommended safety tips:
-
Slow Down – Driving at high speeds in fog can be deadly. Reduce your speed and allow more time to reach your destination.
-
Use Low-Beam Headlights – High beams can reflect off the fog, making it even harder to see. Low beams improve visibility.
-
Increase Following Distance – Keep extra space between your car and the vehicle ahead to avoid sudden collisions.
-
Stay Alert for Stopped Vehicles – In low visibility, vehicles may stop unexpectedly, making rear-end collisions more likely.
-
Avoid Sudden Lane Changes – Smooth and steady driving reduces the risk of losing control in foggy conditions.
What’s Next?
Meteorologists predict fog will begin forming in the early morning hours and gradually lift by mid-morning, once temperatures rise and sunlight breaks through. However, residual moisture may still make roadways slick, and areas prone to low-lying fog could see visibility issues beyond 9:00 A.M.
The NWS advises residents to check for real-time updates before heading out. Those who can delay travel until later in the morning are encouraged to do so.
Stay Informed
For the latest weather and road conditions, residents can visit the National Weather Service website, tune in to local news updates, or use weather apps that provide live fog tracking and alerts.
Final Warning for Drivers
With fog-related crashes being a leading cause of highway accidents, taking precautions is not just recommended—it could save lives. Be prepared, drive carefully, and stay alert as Mississippi faces another round of dense morning fog.
