On Friday at 6:09 p.m. the National Weather Service issued a dense fog advisory in effect until 9 p.m. for Etowah, Calhoun, Cherokee, Cleburne, St. Clair, Talladega and Clay counties.

The weather service says, “Visibility one quarter mile or less in dense fog.”

“Gusty winds could blow around unsecured objects. Tree limbs could be blown down and a few power outages may result. Hazardous driving conditions due to low visibility,” adds the weather service. “Use extra caution when driving, especially if operating a high profile vehicle. Secure outdoor objects. If driving, slow down, use your headlights, and leave plenty of distance ahead of you.”

Guidance from the weather service for navigating foggy conditions

If a dense fog advisory is issued for your area, it means that widespread dense fog has developed and visibility often drops to just a quarter-mile or less. These conditions can make driving challenging, so exercise extreme caution on the road, and if possible, consider delaying your trip.

If driving in fog becomes unavoidable, remember these safety tips:

Moderate your speed:

• Slow down and allocate extra travel time 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 lights, as they create glare, making it more difficult for you to see what’s ahead of you on the road.

Keep your distance:

• Maintain a significant following distance to account for abrupt stops or shifts in traffic patterns.

Stay in your lane:

• To ensure you are staying in the correct lane, use the road’s lane markings as a guide.

Visibility near zero:

• In cases of near-zero visibility due to dense fog, initiate your hazard lights and locate a secure spot, such as a nearby business parking area, to pull over and come to a halt.

Limited parking options:

• If there is no parking lot or driveway to pull into, pull your vehicle off to the side of the road as far as possible. Once you come to a stop, turn off all lights except your hazard flashing lights, set the emergency brake, and take your foot off of the brake pedal to be sure the tail lights are not illuminated so that other drivers don’t mistakenly run into you.

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