The Swedes Fire has burned 1,995 acres and threatens 400 structures southeast of Oroville. On Monday morning, Cal Fire reported one residential structure, one garage, three outbuildings and multiple vehicles destroyed. More than 20 streets in the neighborhoods around Swede Flat Road and Oro Bangor Highway have been evacuated.
Erratic winds and steep terrain make containment a challenge, Cal Fire officials said.. The fire's dynamic nature means evacuation orders can change rapidly, according to a Cal Fire report.
