The Santa Ana winds and the accompanying raging wildfires have been a part of the ecosystem of the Los Angeles Basin for over 5,000 years, dating back to the earliest habitation of the region by the Tongva and Tataviam peoples.[12]
The Santa Ana winds have been recognized and reported in English-language records as a weather phenomenon in Southern California since at least the mid-1800s.[1] Various episodes of hot, dry winds have been described over this history as dust storms, hurricane-force winds, and violent north-easters, damaging houses and destroying fruit orchards. Newspaper archives have many photographs of regional damage dating back to the beginnings of news reporting in Los Angeles. When the Los Angeles Basin was primarily an agricultural region, the winds were feared particularly by farmers for their potential to destroy crops.[1]
The winds are also associated with some of the area's largest and deadliest wildfires, including the state's largest fire on record, the Cedar Fire, as well as the Laguna Fire, Old Fire, Esperanza Fire, Santiago Canyon Fire of 1889 and the Witch Fire.
In October 2007, the winds fueled major wild fires and house burnings in Escondido, Malibu, Rainbow, San Marcos, Carlsbad, Rancho Bernardo, Poway, Ramona, and in the major cities of San Bernardino, San Diego and Los Angeles. The Santa Ana winds were also a factor in the November 2008 California wildfires.
In December 2011, the winds led to "state of emergency" declarations in several municipalities after 80+ mph gusts toppled hundreds of trees, power lines, and traffic signals throughout the San Gabriel Valley. Approximately 230,000 people were left without power for an extended period after the incident.[13]
In May 2014, the winds initiated the San Diego County fires, months after the Colby Fire in northern Los Angeles County.
