California greets the morning under a gray lid of fog and smoke, blurring skylines and dimming headlights across Los Angeles. Low visibility and unhealthy air combine to create a slow, cautious start for commuters heading out early.
According to the National Weather Service and the South Coast Air Quality Management District, a Dense Fog Advisory remains in effect until 10 a.m. PST for much of Los Angeles County, including downtown, coastal areas, and nearby valleys. Visibility may drop to one-quarter mile or less, especially near beaches and low-lying roadways.
At the same time, an Air Quality Alert remains active today across the South Coast Air Basin. A mandatory wood-burning ban is in place for Los Angeles and Orange counties. Burning wood, pellets, or manufactured fire logs is prohibited indoors and outdoors, with limited exemptions. Officials say fine particle pollution can trigger asthma attacks and worsen heart and lung conditions.
Drivers should expect reduced visibility on major routes like I-5, I-10, and U.S. 101 through the morning hours. Slow down, use headlights, and leave extra distance between vehicles. Conditions may improve by late morning as fog gradually lifts.
Temperatures remain mild for December, with highs near 80 degrees today and light winds. Clearer skies are expected Wednesday and Thursday, with daytime highs staying in the upper 70s to low 80s. Patchy fog could return during late-night and early-morning hours later this week.
Looking toward the weekend, models hint at continued dry conditions with mild afternoons and cooler nights in the mid-50s. While no rain or winter weather is expected, air quality concerns may persist during calm periods.
Limit outdoor activity if you’re sensitive to smoke, and keep travel plans flexible this morning.
