Hurricane force winds are fanning the flames of the Southern California wildfires. What are Santa Ana winds?

At least five wildfires are ravaging Southern California, and the three largest — which are at 0% containment — have already killed at least two people, burned thousands of acres and prompted the evacuation of about 70,000 residents. Santa Ana winds coupled with dry conditions have created the perfect storm for the fires to spread. 

Hurricane-force winds have fanned the flames of the Palisades Fire, currently burning on the west side of Los Angeles County in coastal communities including Pacific Palisades and Malibu. The winds are also blowing the embers of the Eaton Fire, which is impacting the cities of Pasadena and Altadena in northeast L.A. County.
