The National Weather Service has issued a Dense Fog Advisory for the Orange and San Diego County Coasts.
The fog will creep inland about five miles, so expect visibility to be reduced down to a quarter-mile or less.
Remember to use your low beams, give yourself plenty of space from the car ahead of you, turn off the radio and listen for traffic, and most importantly, reduce your speed.
The Dense Fog Advisory expires at nine tomorrow morning, but a repeat could impact the Saturday morning commute.
