Dangerous Santa Ana winds are expected to return to the Los Angeles area this week, potentially fueling the growth of new and existing wildfires, according to FOX Weather.

Santa Ana winds are caused by strong high pressure over the Great Basin region of the West creating a pressure gradient that amps up winds through the mountains, foothills and sometimes valleys of Southern California. In this case, the winds are getting a major boost from a strong upper-level low pushing southward across the state.

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

Santa Ana winds are one of the nation's most notorious wind events and an ongoing weather hazard in Southern California.

Los Angeles’ wildfires are still burning two weeks after they sparked — and the City of Angels could be in for deeper trouble as the hurricane-force winds that first fanned the flames return to the region.

Gusty Santa Ana winds will return to start the week, posing concerns for dangerous fire conditions in Southern California, including Los Angeles. The strong, dry winds will be favorable for the start of new fires as well as the rapid spread of current fires.

Residents and firefighters across Southern California braced for another round of fierce Santa Ana winds on Tuesday.
