The Tubbs Fire, located just north of Santa Rosa, grew from 200 acres on Sunday night (October 8) to over 20,000 acres by Monday morning (October 9) and is now over 27,000 acres. As of 4 p.m. Pacific Time (PT) on Monday, October 9, the Tubbs Fire together with the Atlas Peak Fire, located just north of Napa, combined have destroyed over 50,000 acres of land, and impacted several wineries along with high value residential and commercial structures. So far, 1,500 structures are reportedly destroyed, making this at least the fifth most destructive fire in California history as shown in the table below.
