North Bay Interior Valleys and East Bay Interior Valleys were placed under a dense fog advisory by the National Weather Service on Saturday at 4:31 a.m. The advisory is in effect until 11 a.m.
The NWS San Francisco CA adds to expect, “Visibility one quarter mile or less in dense fog.”
“Low visibility could make driving conditions hazardous,” according to the NWS. “If driving, slow down, use your headlights, and leave plenty of distance ahead of you.”
Guidance from the NWS 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:
Reduce speed:
Slow down and allow extra travel time to reach your destination safely.
Visibility matters:
Ensure your vehicle is visible to others by using low-beam headlights, which automatically activate your taillights. Utilize fog lights if your vehicle is equipped with 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:
Use the road’s lane markings as a guide to staying in the correct lane.
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.
No 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 precautions from the NWS, you can navigate foggy conditions more safely, reducing the likelihood of accidents and ensuring your personal safety.
