Thousands of firefighters have prepared for a tougher fight against California's largest wildfire as extremely dangerous weather returns, threatening to stoke flames into explosive growth.
Firefighters were able to save homes and hold large stretches of the blaze but a red flag warning was scheduled for Wednesday afternoon through Thursday because of hot, bone-dry conditions with winds up to 40 mph. That could drive flames through timber, brush and grass, especially along the northern and northeastern sides of the vast blaze.
"I think we definitely have a few hard days ahead of us," said Shannon Prather with the U.S. Forest Service.
The Dixie Fire jumped perimeter lines in a few spots Tuesday, prompting additional evacuation orders for some 15,000 people, fire officials said.
Firefighters prevented flames on Monday from reaching homes in the small Northern California community of Greenville near the Plumas National Forest as the 3-week-old fire grew to over 395 square miles across Plumas and Butte counties.
On Tuesday, spot fires jumped some of the perimeters and burned several acres of brush on the western side of the blaze, even though crews had cut back areas of unburned fuel with bulldozers and dumped some 230,000 gallons of fire retardant, said Mike Wink, a state fire operations section chief.
Heat from the flames also created a pyrocumulus cloud, a massive column of smoke that rose 30,000 feet in the air, he said.
The fire has threatened thousands of homes and destroyed 67 houses and other buildings since breaking out July 14. It was 35% contained.
