On Thursday at 2:11 a.m. a dense fog advisory was issued by the National Weather Service in effect until 7 a.m. for Orange County.
The NWS San Diego CA adds to expect, “Visibility one quarter mile or less in dense fog.”
“Gusty winds will blow around unsecured objects. Tree limbs could be blown down and a few power outages may result. 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. Winds this strong can make driving difficult, especially for high profile vehicles. Use extra caution.”

Navigating fog: Safety tips by the NWS
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 you must drive in foggy conditions, keep the following safety tips in mind:
Reduce speed:
Slow down and allocate extra travel time 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 lights, as they create glare, making it more difficult for you to see what’s ahead of you on the road.
Keep your distance:
Keep a considerable following distance to account for sudden 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 cases of near-zero visibility due to dense fog, activate your hazard lights and seek a safe spot, like a nearby business parking lot, to pull over 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.
