Recent wildfires in Northern California, specifically in Napa and Sonoma counties, have sparked widespread devastation across the area to lives, homes, and businesses. Despite the fires still being active, and the numbers still being calculated, this event is already “the deadliest and most destructive series of wildfires in California history,” and among the worst in U.S. history. And with damages estimated between $3 billion and $6 billion (which could still rise), insurers may face another massive payout due to natural catastrophes in 2017. These devastating events are proof that data is the only line of defense for insurers. And, it’s more paramount than ever, to gain a better understanding of how you can use data to better mitigate and underwrite wildfire risk going forward.
