Dense fog advisory active for Delta until Monday midday – visibility down to 1/4 mile

Carquinez Strait and Delta, Southern Sacramento Valley and Northern San Joaquin Valley were placed under a dense fog advisory by the National Weather Service on Monday at 8:47 a.m. The advisory is in effect until 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,” according to the NWS. “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 in fog becomes unavoidable, remember these safety tips:

Moderate your 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 you have fog lights, use them.

Avoid high-beams:

Refrain from using high-beam headlights, as they create glare that impairs your visibility 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.

Zero visibility strategy:

In situations of near-zero visibility due to dense fog, activate your hazard lights and seek a secure location, such as a nearby business’s parking lot, to pull over and come to a 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.
