In early September 2020, a combination of a record-breaking heat wave and strong katabatic winds, (including the Jarbo, Diablo, and Santa Ana) caused explosive fire growth. The August Complex became California's largest recorded wildfire. The Creek Fire expanded in the Big Creek drainage area, temporarily trapping hundreds of campers near the Mammoth Pool Reservoir. The North Complex explosively grew in size as the winds fanned it westward, threatening the city of Oroville, triggering mass evacuations, and causing 16 fatalities.
