Dense fog advisory in place for Delta for Sunday – visibility down to 1/4 mile

Carquinez Strait and Delta, Southern Sacramento Valley and Northern San Joaquin Valley are included in a dense fog advisory released by the National Weather Service on Saturday at 10:14 p.m. The advisory is valid for Sunday, Nov. 23 between 3 a.m. and 11 a.m.

The NWS Sacramento CA says 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

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 through fog becomes inevitable, remember these safety guidelines:

Moderate your 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.

Limited 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.
