An "urgent weather message" from the National Weather Service at 2:45 a.m. warns of a dense fog advisory throughout portions of the Los Angeles region including downtown, coastal areas in LA County, San Gabriel Valley, Santa Clarita Valley, Ventura and Santa Barbara. It could reduce freeway and roadway visibility to "one quarter mile or less through mid morning," the service says. The advisory officially will end at 9 a.m., so enjoy it while it lasts.
