The National Weather Service issued a report at 8:23 p.m. on Monday for fog until Tuesday at 6 a.m. for Madison, Morgan, Marshall, Jackson, DeKalb and Cullman counties.

“Patchy freezing fog has developed across portions of north central Alabama, northeast Alabama and southern Middle Tennessee this evening, with visibilities generally in the 1-3 mile range. As temperatures continue to slowly fall below freezing, the risk for a very thin glaze of ice to be deposited on elevated surfaces will increase through early Tuesday morning. At this point, the freezing fog appears to be confined to larger valleys in the region. Stay tuned to NOAA Weather Radio, or a favorite local media outlet, for further statements or updates from the National Weather Service in Huntsville,” states the weather service.

Navigating fog: Safety tips by the weather service

If you need to drive through fog, remember these safety guidelines:

Moderate your speed:

• Slow down and allocate extra time for your trip to reach your destination safely.

Visibility matters:

• Ensure your vehicle is visible to others by using low-beam headlights, which also activate your taillights. If you have fog lights, use them.

Avoid high-beams:

• Refrain from using high-beam headlights, as they create glare that impairs your visibility on the road.

Keep your distance:

• Maintain a generous following distance to account for abrupt stops or shifting traffic patterns.

Stay in your lane:

• Use the road’s lane markings as a guide to staying in the correct lane.

Visibility near zero:

• In extremely dense fog where visibility is near zero, the best course of action is to first turn on your hazard lights, then simply pull into a safe location such as a parking lot of a local business, and stop.

No parking options:

• If no parking area is available, pull your vehicle as far to the roadside as possible. Once stationary, turn off all lights except the hazard flashers, engage the emergency brake, and release the brake pedal to ensure your tail lights are not illuminated, reducing the risk of other drivers colliding with your stationary vehicle.

By adhering to these recommendations from the weather service, you can navigate foggy conditions with greater safety, mitigating the risk of accidents and prioritizing your well-being.
