The Thomas Fire grew to 242,500 acres Wednesday night into Thursday, making it the fourth largest fire in California’s history.
Crews kept containment at 30 percent.
Since the fire broke out Dec. 4, 972 structures have been destroyed, and another 221 have been damaged. 18,000 remain threatened.
Cal Fire expects “most significant fire growth” to happen on the west, while dangerous fire conditions — high fuel, low humidity and above-average temperatures — continue the fire’s spread on the north and east, as well.
Fire officials said this week that the Thomas Fire may not be stopped until it hits burn scars from recent blazes.
