Dense Fog and Reduced Visibility

A thick blanket of fog has settled across much of San Diego County, significantly reducing visibility in many areas. This San Diego fog is particularly impacting coastal regions, with reports of near-zero visibility in some locations. This coastal fog is expected to persist throughout the morning.

• Impact on morning commutes: Expect significant delays on your morning commute. Roads will be slick, and reduced visibility makes driving treacherous.
• Visibility challenges for drivers: Drive with extreme caution. The low visibility created by this San Diego fog presents a serious safety hazard.
• Safety precautions to take while driving in fog: Slow down significantly, increase your following distance, use your low-beam headlights (high beams reflect off the fog and reduce visibility), and avoid sudden braking or lane changes.
• Areas with the highest fog density: Coastal areas, including the areas near La Jolla, Del Mar, and Carlsbad, are experiencing the densest fog. Inland areas are seeing less fog but still experiencing reduced visibility.
• Expected duration of the fog: The fog is expected to gradually dissipate later this morning, but patchy fog may persist into the afternoon in certain coastal areas. Stay informed about San Diego fog conditions throughout the day.
