Dense fog advisory affecting Delta until Thursday morning – 1/4 mile visibility

Carquinez Strait and Delta, Northern Sacramento Valley, Central Sacramento Valley, Southern Sacramento Valley and Northern San Joaquin Valley are the focus of a dense fog advisory issued at 3:27 a.m. on Thursday by the National Weather Service. The advisory is in effect until 10 a.m.

The NWS Sacramento CA says to prepare for, “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 driving in fog becomes unavoidable, remember these safety tips:

Moderate your speed:

Slow down and allocate extra travel time 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 lights, as they create glare, making it more difficult for you to see what’s ahead of you on the road.

Keep a safe distance:

Maintain a generous following distance to account for abrupt stops or shifting 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 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.
