Fueled by winds, largest wildfire moves near California city

GRIZZLY FLATS, Calif. (AP) — Firefighters faced dangerously windy weather Tuesday as they struggled to keep the nation’s largest wildfire from advancing toward a Northern California city while a portrait of devastation emerged in a small mountain community hit by another inferno.

Winds spawned by the arrival of a new weather system Monday afternoon pushed the monstrous Dixie Fire to within about 8 miles (12.8 kilometers) of Susanville, population about 18,000, while to the southeast a small blaze called the Caldor Fire exploded through through Grizzly Flats, a town of about 1,200.

Very few homes were left standing in Grizzly Flats, where streets were littered with downed power lines and poles. Houses were reduced to smoldering ash and twisted metal with only chimneys rising above the ruins. A post office and elementary school were also destroyed.

At the Dixie Fire, numerous resources were put into the Susanville area, where residents were warned to be ready to evacuate, said Mark Brunton, an operations section chief.

“It’s not out of play, and the next 24 hours are going to be crucial to watch as to what the fire is going to do there,” he told an online briefing.

To the east, spot fires became established south of the small community of Janesville, which had been ordered evacuated. Some structures were lost there — images captured by The Associated Press showed a home consumed by flames — but a surge of firefighters was able to herd the fire around the majority of the town, Brunton said.

The Dixie Fire is the largest of nearly 100 major wildfires burning across more than a dozen Western states that have seen historic drought and weeks of high temperatures and dry weather that have left trees, brush and grasslands as flammable as tinder. Climate change has made the U.S. West warmer and drier in the past 30 years and will continue to make the weather more extreme and wildfires more destructive, according to scientists. Susanville is the seat of Lassen County and the largest city that the Dixie Fire, named for the road where it started, has approached since it broke out last month. The former Sierra Nevada logging and mining town has two state prisons, a nearby federal lockup and a casino. Ash fell from the advancing fire and a police statement urged residents “to be alert and be ready to evacuate” if the fire threatens the city.

The weather forecast prompted Pacific Gas & Electric to warn that it might cut off power to 48,000 customers in parts of 18 California counties Tuesday evening through Wednesday to prevent new fires that could be sparked by wind damage to power lines.

The Dixie Fire has scorched more than 940 square miles (2,434 square kilometers) in the northern Sierra Nevada and southern Cascades since it ignited on July 13 and eventually merged with a smaller blaze. It’s less than a third contained. Investigations are continuing, but PG&E has notified utility regulators that the Dixie and Fly fires may have been caused by trees falling into its power lines.
