The 2017 California wildfire season was the most destructive wildfire season on record, which saw multiple wildfires burning across California. A total of 9,133 fires burned 1,381,405 acres, according to the California Department of Forestry and Fire Protection, including five of the 20 most destructive wildland-urban interface fires in the state's history. Throughout 2017, the fires destroyed or damaged more than 10,000 structures in the state, a higher tally than the previous nine years combined. State data showed that the large wildfires killed 43 people – 41 civilians and 2 firefighters – almost higher than the previous 10 years combined.
Throughout the early months of 2017, there was heavy rainfall over most of California, which triggered widespread flooding, thus temporarily mitigating the state's historic drought conditions. However, according to a report published by the National Interagency Fire Center, the potential for large fires was "expected to remain near normal through the spring, but once fine fuels dry out, there will likely be a spike in grass fire activity.”
