Smoke from wildfires in Los Angeles is drifting to the San Diego region, causing a dip in air quality and prompting North County fire officials to issue a smoke advisory.

Forecasters say weaker winds will hit on Saturday night and Sunday, and that there will be no relief until the county gets rain.

Santa Anas winds blustered the inland valleys and mountains Thursday amid a continued Red Flag Warning, with some areas in the region experiencing wind speeds over over 75 mph.

Usually, when there are wildfires in Los Angeles, smoke would make its way to San Diego. So far that hasn’t been the case.

Firefighters welcomed a break Saturday morning from the dangerous Santa Ana winds. But the reprieve will only be measured in hours, as strong winds return later Saturday.

Fast-moving Santa Ana winds – some as powerful as a hurricane – have been roaring across Southern California and feeding the wildfires firefighters are battling in the Los Angeles area. And the heightened fire risk will continue into next week.

Red Flag Warnings remain in effect through Friday evening for much of Los Angeles and Ventura Counties, the National Weather Service said.
