At 9:04 p.m. on Wednesday, the National Weather Service released a dense fog advisory in effect until Thursday Nov. 27, at 10 a.m. for East Bay Interior Valleys.
The NWS San Francisco CA says to be ready for, “Visibility one quarter mile or less in dense fog.”
“Hazardous driving conditions due to low visibility,” the NWS said. “If driving, slow down, use your headlights, not your brights, 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 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 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.
Maintain safe gaps:
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.
Zero visibility strategy:
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 NWS, you can navigate foggy conditions with greater safety, mitigating the risk of accidents and prioritizing your well-being.
