On Monday at 10:03 p.m. the National Weather Service issued a dense fog advisory in effect until Tuesday Nov. 25, at 11 a.m. for North Bay Interior Valleys.
The NWS San Francisco CA says to expect, “Visibility one quarter mile or less in dense fog.”
“Low visibility could make driving conditions hazardous. Limited visibility will result in hazardous driving conditions,” according to the NWS. “If driving, slow down, use your headlights, and leave plenty of distance ahead of you. If commuting, allow extra drive time to reach your destination safely.”
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:
Moderate your 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.
Maintain safe gaps:
Keep a considerable following distance to account for sudden stops or shifts in traffic patterns.
Stay in your lane:
Use the road’s lane markings as a guide to remaining 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 designated parking area is available, pull your vehicle as far off the road as possible. Once stationary, deactivate all lights except the hazard flashers, engage the emergency brake, and release the brake pedal to ensure your tail lights remain unlit, minimizing the chance of other drivers colliding with your stationary vehicle.
By adhering to these recommendations from the NWS, you can navigate foggy conditions more safely, reducing the risk of accidents and ensuring your well-being.
