The National Oceanic and Atmospheric Administration (NOAA) defines Santa Ana winds as, βa weather condition in which strong, hot, dust-bearing winds descend to the Pacific Coast around Los Angeles from inland desert regions.β They start out as an area of high pressure over the Great Basin-the dry and mountainous region between the Sierra Nevada and Rocky Mountains. Santa Ana winds are named for one of the canyons through which they tend to blow, and Diablo winds are named for the Diablo Mountain Range, below which they tend to occur. Ordinarily at this time of year wildfire risk in the state is heightened by two seasonal winds in particular: the Santa Ana and Diablo. The situation was caused by what the National Weather Service described as βan anomalously amplified upper level pattern across the nation,β which created exceptionally strong gusty winds in California. This is not a new category of warning, but rather enhanced language to convey the unusual severity of the risk. On October 30, the National Weather Service issued an extreme red flag warning for wildfire risk in Southern California. Although these fires collectively burned through thousands of acres in different areas, one major factor driving them all is wind. Multiple wildfires in both Northern and Southern California raged in October.
