Jackson, Kentucky.Drivers in eastern Kentucky should brace themselves for pockets of heavy valley fog early Friday morning, which could reduce visibility to less than a quarter mile in certain areas.
Areas of Concern
The strongest fog will develop in low-lying valleys, affecting counties from Rowan and Estill to Pike and Harlan, according to the Jackson National Weather Service. Particularly dangerous locations include:
United States 23
The Mountain Parkway
Roads in rural areas close to rivers and hollows where fog accumulates
Weather Conditions Causing the Fog
High humidity, clear skies, and calm winds are all combining to provide the ideal conditions for nocturnal fog formation.
Travel Safety
Drivers are advised to:
Reduce speed and lengthen the following distance.
Use headlights with low beams to prevent glare.
Give yourself extra time to travel in the morning.
Particularly when descending from hill tops into valleys, visibility could abruptly alter.
Clearing Timeline
Between 8 and 9 a.m., the fog is predicted to clear, and the rest of the day will be characterized by generally sunny sky. Over the weekend, a similar morning fog can reappear if the calm, clear weather persists.
