• Coastal fog is impacting visibility in Northern California counties including El Dorado, Nevada, Placer, Sacramento, San Joaquin, Solano, Stanislaus, Yolo, Yuba, and Sutter.
• The fog is caused by cooler air moving over warmer ocean surfaces, a common weather pattern during the transition from winter to spring.
• Residents and travelers are advised to exercise caution, reduce speed, and increase following distances due to reduced visibility.
