This swarm of wildfires was exacerbated by unusually powerful and long-lasting Santa Ana winds,[24] as well as large amounts of dry vegetation, due to a then-far unusually dry rainy season thus far. They also occurred at the end of an unusually active and destructive wildfire season; the fires cost at least $3.5 billion (2018 USD) in damages, including $2.2 billion in insured losses and $300 million in fire suppression costs.[2][3]
