Authorities say nearly 7,000 homes and structures were destroyed in Northern California’s deadly wildfires, and the number is expected to increase. California Department of Forestry and Fire Protection spokesman Daniel Berlant said most destruction happened Oct. 8 and Oct. 9 when fires initially broke out in California’s famed wine counties of Sonoma and Napa plus neighboring areas. More than 15,000 people remained evacuated on Thursday as crews reported progress containing the fires. A wildfire that broke out Sonoma County is now the third deadliest fire in state history. It killed 22 of the 42 people who have died in the California’s October wildfires. A 1993 Los Angeles fire that killed 29 people was the state’s deadliest. A 1991 fire in Oakland, California, killed 25 people and was the second deadliest.
