North Bay Interior Valleys and East Bay Interior Valleys are included in a dense fog advisory released by the National Weather Service on Saturday at 9:01 p.m. The advisory is in effect until Sunday Dec. 14, at 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,” the NWS said. “If driving, slow down, use your headlights, and leave plenty of distance ahead of you.”
Guidance from the NWS for navigating foggy conditions
When a dense fog advisory is issued for your area, it means that widespread dense fog has developed and visibility can plummet to a quarter-mile or less. These conditions pose challenges for travel, so exercise extra caution on the road or consider postponing your trip if possible.
If you must venture out in foggy conditions, keep these safety tips from the NWS in mind:
Reduce speed:
Slow down and allocate extra time for your trip to reach your destination safely.
Visibility priority:
Ensure your vehicle is visible to others by using low-beam headlights, which also activate your taillights. If available, employ your fog lights.
Avoid high-beams:
Refrain from using high-beam headlights, as they create glare that impairs your visibility on the road.
Keep a safe 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.
Zero visibility strategy:
In situations of near-zero visibility due to dense fog, activate your hazard lights and seek a secure location, such as a nearby business’s parking lot, to pull over and come to a stop.
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.
