Storms threaten to grow monstrous Dixie fire: ‘Everything is ready to burn’

Gusts of up to 40 mph could carry burning embers, while lightning strikes could further ignite parched wildlands, swelling the already massive Dixie fire. Firefighters could get a break overnight, forecasters said, but adverse weather conditions are likely to return Friday.

A chance of thunderstorms converging Thursday over the burn zone of the Dixie fire could inject a dangerous element of instability into already treacherous conditions and fuel further growth of the massive fire, officials said.

Storms were forecast arrive over the blaze in Northern California in the afternoon, bringing wind gusts of up to 40 mph and a chance of lightning, according to incident meteorologists for the fire.

Winds of that ferocity not only can drive the fire’s forward march, but also can hurl embers over containment lines and spark new fires. Lightning strikes in historically dry vegetation can similarly ignite new flames.

With the region engulfed in a drought, “everything is ready to burn,” said Diondray Wiley, a fire behavior analyst for the Dixie fire.

After igniting a month ago, the Dixie fire has now seared 510,227 acres. It is the second-largest wildfire in California history and the 15th most destructive, burning more than 550 homes. It has scorched parts of Plumas, Lassen, Butte and Tehama counties, north of Sacramento, and was 30% contained as of Thursday.

Pacific Gas & Electric has said its equipment might have sparked the Dixie fire, which broke out July 13 near the utility’s power station in Feather River Canyon, as well as another blaze that later merged with the Dixie fire.

The blaze grew overnight by about 10,000 acres, primarily in the Diamond Mountain area on the eastern side, said Capt. Daniel Bertucelli, a public information officer for the Dixie fire.

The fire has spurred multiple evacuation orders and warnings across several counties. Many roads are closed, as well as nearby national forests.

Roughly 32% of the Plumas County population was under evacuation orders or warnings Wednesday, according to the county Sheriff’s Office. Directives are frequently changing, and up-to-date information can be found at the Plumas County Sheriff’s Office Facebook page.

Evacuation orders for the Lassen County communities of Westwood, Clear Creek and Pine Town remain in place. More details can be found at the Lassen County Sheriff’s Office Facebook page

Firefighters are worried the blaze could spread farther and faster when storms roll into the area later in the day.

Thunderstorms could continue through Thursday evening, said Joseph Goudsward, an incident meteorologist for the Dixie fire.

The area over Lake Almanor and to the north, toward the Lassen National Forest, is the “sweet spot” for the storms to develop, Goudsward said during a briefing Thursday morning. He said outflow winds would plague the entire fire area, and depending on topography, winds could reach 30 to 40 mph.

Temperatures will remain high — around 90 degrees — and humidity low during the day.

“We’re warm. We’re dry. We’re unstable,” Goudsward said.

Smoke has hung heavy over the fire, moderating temperatures and fire behavior in recent days. But a slight clearing can send air hurtling upward, said Bladen Breitreiter, another incident meteorologist for the fire.

“If we do bust through this smoke, we are going to see some plumes,” Goudsward said Thursday. “No doubt in my mind; the atmosphere is ripe for it.”

The storms are expected to die down in the early evening, with another possible surge around 9 p.m., and could return Friday.

Meanwhile, drought conditions are fueling other destructive fires throughout the state.

To the west of the Dixie fire, in Trinity and Shasta counties, a pair of wildfires sparked by lightning in late July when thunderstorms passed through the area have seared roughly 100,000 acres between them.

The Monument fire had ballooned to 67,190 acres by Thursday and was only 3% contained. The blaze has consumed at least 31 buildings, according to local media reports, and firefighters are actively defending several communities.

Evacuation orders are in place for the communities of Junction City, Red Hill, Canyon Creek, Coopers Bar, Big Bar, Del Loma, Big Flat, Helena, Cedar Flat and Burnt Ranch. A portion of Highway 299 is closed. More detailed evacuation information can be found on the Trinity County’s Sheriff’s Office Facebook page.

About 20 miles to the south, the McFarland fire has swelled to 37,779 acres. Though 51% contained, the blaze could spread rapidly amid parched conditions, officials said. Evacuation warnings remain in place for the communities of Wildwood; Post Mountain, near the junction of State Routes 36 and 3; Trinity Pines; and Platina.

Last week, a former college instructor linked to a rash of arson fires was charged with igniting a blaze on federal forest land, not far from the Dixie fire.

Gary Stephen Maynard, 47, was charged with willfully starting the Ranch fire, which started Saturday in Lassen National Forest and burned about an acre, according to documents filed in federal court this week.

Maynard is also suspected in at least six other fires that ignited in the Lassen and Shasta-Trinity National Forests in the last month, court documents show.
