Hot, gusty weather could mean explosive fire growth in West
“I think we definitely have a few hard days ahead of us,” said Shannon Prather with the U.S. Forest Service.
{{#rendered}} {{/rendered}}California’s largest wildfire continued to grow Wednesday as thousands of firefighters prepared for a tougher fight as dangerous weather returns.
A red flag warning was issued through Thursday because of hot, bone-dry conditions with winds up to 40 mph (64 kph). That could drive flames through timber, brush and grass, especially along the northern and northeastern sides of the vast Dixie Fire.
"I think we definitely have a few hard days ahead of us," said Shannon Prather with the U.S. Forest Service.

Firefighters were able to save homes and hold large stretches of the blaze, but flames jumped perimeter lines in a few spots Tuesday, prompting additional evacuation orders for some 15,000 people, fire officials said.

Heat from the flames created a pyrocumulus cloud, a massive column of smoke that rose 30,000 feet (10,000 yards) in the air, said Mike Wink, a state fire operations section chief.
The fire has threatened thousands of homes and destroyed 67 houses and other buildings since breaking out July 14. It was 35% contained.
About 150 miles (240 kilometers) to the west, the lightning-sparked McFarland Fire threatened remote homes along the Trinity River in the Shasta-Trinity National Forest. The fire was only 5% contained. It had burned fiercely through nearly 25 square miles (65 square kilometers) of drought-stricken vegetation.

Similar risky weather was expected across Southern California, where heat advisories and warnings were issued for interior valleys, mountains and deserts for much of the week.
Heat waves and historic drought tied to climate change have made wildfires harder to fight in the American West. Scientists say climate change has made the region much warmer and drier in the past 30 years and will continue to make weather more extreme and wildfires more frequent and destructive.
More than 20,000 firefighters and support personnel were battling 97 large, active wildfires covering 2,919 square miles (7,560 square kilometers) in 13 U.S. states, the National Interagency Fire Center said.
