Meteorologists said there was a chance the winds would be as severe as those that fueled the Palisades and Eaton fires, but that different locations would likely be affected.

In recent days, however, the region’s powerful Santa Ana winds—which have been fanning the flames—have begun to slow down. This lull has offered firefighters a reprieve and a key opportunity to make progress against the blazes, but forecasts suggest the Santa Ana will return next week. What are these gusts, and how have they become so strong?

The Santa Ana winds fanning wildfires that have killed at least 25 people in Southern California and destroyed more than 10,000 houses, businesses and other structures in Greater Los Angeles are flaring up again.

Now, Santa Ana winds are expected to sweep through the area early next week, accompanied by low humidity, meaning more potentially dangerous fire conditions. Here's what to expect over the weekend and into next week.

A "Particularly Dangerous Situation" warning remains in effect as strong winds cause extreme fire danger in Southern California.

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.

Wildfires fueled by strong Santa Ana winds have devastated Southern California, destroying thousands of homes and causing 27 deaths. The fires, affecting urban areas and the Olympic preparation, are worsened by climate change and urban expansion.

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