In a matter of days, the LNU Lightning Complex -- named for the fires ignited by a rash of thunderstorms early this week had charred 124,000 acres and was 0% contained, according to Cal Fires latest status report posted 7 p.m. Wednesday.
The series of small and massive blazes ignited by a rash of thunderstorms last week are spread across Napa, Sonoma, Lake, Solano and Yolo counties, engulfing the North Bay in flames and smoke and spurring tens of thousands of residents to evacuate.
The fire has destroyed 105 structures, damaged 70 and threatens 25,000, Cal Fire said.
The agency described the fires behavior as "extreme," with stretched firefighting crews battling flames racing in all directions and being thrown long distances by high winds. The blaze threatens multiple communities.
An arm of the blaze took a dramatic turn early Wednesday, burning over hills and through valleys, racing toward the community of Vacaville, where residents were roused before dawn Wednesday by orders to flee. Police and firefighters went door-to-door in a frantic scramble to warn residents to evacuate as flames encroached.
