SAN DIEGO – A thick blanket of coastal fog hugs the freeways and beaches of Southern California this morning, cutting visibility to a few hundred feet in spots from Oceanside to Mission Viejo. The National Weather Service in San Diego has issued a Dense Fog Advisory until 8 a.m. PST, warning drivers across Orange and San Diego counties to use caution and low beams while traveling.
Visibility could drop below a quarter mile in dense patches, especially along I-5, Highway 78, and stretches of I-805 through the inland valleys. Once the fog burns off, skies will gradually clear to mild sunshine, with highs climbing into the mid-70s by afternoon — a calm lead-in to a much wetter pattern developing later this week.
According to the National Weather Service, a Pacific storm system is expected to arrive Thursday, bringing widespread rain and the potential for localized heavy downpours and isolated thunderstorms Thursday night into Friday. Some coastal and inland areas could see more than half an inch of rainfall, with higher totals in foothill zones. Forecasters urge residents to plan ahead for slower commutes, slick roads, and possible ponding near low-lying intersections.
By the weekend, the system will push east, leaving behind partly sunny skies and more seasonable temperatures. Still, this is the strongest November storm to target Southern California so far this fall — a clear sign that the transition toward winter’s wetter rhythm has begun.
