PG&E equipment linked to fire; storms bring threats


Pacific Gas & Electric, the nation’s largest utility, reported to California regulators that its equipment might have been involved in the start of the Dixie Fire burning in the Sierra Nevada. The utility said in a filing Sunday that a repairman responding to a circuit outage on July 13 spotted blown fuses in a conductor atop a pole, a tree leaning into the conductor, and fire at the base of the tree.

PG&E equipment has repeatedly been linked to significant wildfires, including the 2018 blaze that ravaged the Northern California town of Paradise. The Dixie Fire has grown to 29 square miles, mainly in the remote wilderness. The utility said investigators with the California Department of Forestry and Fire Protection, better known as CalFire, have collected equipment from the location.

Meanwhile, powerful storms forecast for parts of the drought-stricken West this week could do more harm than good as “fire clouds” and dry lightning sweep across a region already dotted with wildfires fueled by parched vegetation, heat, and winds. The storms brought flash flooding to Phoenix and other areas of the Southwest, but less rain is forecast farther north.

“These storms can cause cloud-to-ground lightning and ignite fires,” AccuWeather meteorologist Thomas Geiger warned. ally, unstable weather conditions could add to the misery in the coming days, the National Interagency Fire Center warned.

The  More than 80 wildfires were burning through 1,157,976 acres in 13 states, battled by almost 20,000 firefighters.Dixie Fire in north-central California threatened more than 800 homes and other structures. The remoteness of the blaze, along with the steep terrain, was adding to the challenges faced by hundreds of firefighters. “Thunderstorms with abundant lightning & little rainfall could produce new fire starts,” the National Weather Service in Sacramento said.


The fire’s edge is just a few miles from Paradise, which burned almost to the ground in a wildfire three years ago that killed 85 people. But the fire was moving away from the town, and no evacuations were ordered, or evacuation warnings were given as of Monday morning.

Large “pyrocumulus clouds” formed over the Dixie Fire, producing a massive smoke column that further increased fire activity, CalFire said in its latest incident report. Pyrocumulus clouds – fire clouds – look like giant, dirty-colored thunderheads that sit atop a massive column of smoke from a wildfire. The top of the smoke column often flattens to take the shape of an anvil.

In Oregon, the Bootleg Fire also has produced pyrocumulus clouds. That fire has burned almost 500 square miles and is among the largest blazes in Oregon history, but it’s located in a remote area away from population masses. At least 2,000 homes were evacuated at some point during the fire, and another 5,000 were threatened.

Fire authorities say pyrocumulus clouds form from 3 p.m. to 5 p.m. each day as the sun penetrates the smoke layer and heats the ground below, creating an updraft of hot air. The fire, which ignited two weeks ago, remains “very active” and growing because of hot, dry, and breezy conditions, fire officials said in a bleak update late Saturday night.

“Poor humidity recovery at night contributes to active fire spread,” fire managers said. “Drought-affected fuels are generating robust spread rates. Expecting similar conditions for the next several days.”

The Tamarack Fire had burned about 30 square miles along the California-Nevada border. The blaze destroyed several structures and threatened the tiny California hamlet of Markleeville, less than 150. Dena Brown posted on Twitter that her father had to leave his home. “We just had a 6.0 earthquake recently. Now, this. #prayerrequest #TamarackFire,” she wrote.
