CALIF. FIRE NOW LARGEST IN STATE HISTORY

Firefighters are battling against high winds and August heat to slow down the Cal fire, now at 450 square miles.

Firefighters struggled against rugged terrain, high winds and an August heat wave Tuesday to slow the spread of the biggest wildfire ever recorded in California, an inferno that exploded to be nearly the size of Los Angeles in just 11 days.

The 450-square-mile blaze, centered near the community of Upper Lake, about 100 miles north of San Francisco, spread fast because of what officials said was a perfect combination of weather, topography and abundant vegetation turned into highly flammable fuel by years of drought.

Firefighting efforts were also initially hampered by stretched resources, said the Department of Forestry and Fire Protection, also known as Cal Fire.

When the fire started July 27, thousands of firefighters were hundreds of miles north battling a massive blaze that spread into the city of Redding, destroying more than 1,000 homes, in addition to a dozen other major blazes.

A few days after the Upper Lake fire started, Cal Fire Battalion Chief John Messina told a community meeting that with so many fires already raging in California, “resources are already committed,” so officials were forced to prioritize public safety and private property.

“After those two things are addressed, we’ll go after the pieces of fire that are in remote areas,” Messina said. “Typically, we’d go at it all at once. There is just not the resources for that.”

The flames were raging in mostly remote areas, and no deaths or serious injuries were reported. But at least 75 homes have been lost, and thousands of people have been forced to flee. The blaze, dubbed the Mendocino Complex, was reported 20 percent contained Tuesday.

Its rapid growth at the same time firefighters were battling more than a dozen other major blazes across the state fanned fears that 2018 could become the worst wildfire season in California history.

“For whatever reason, fires are burning much more intensely, much more quickly, than they were before,” said Mark A. Hartwig, president of the California Fire Chiefs Association.

About 3,900 firefighters, including a crew of 40 volunteers from New Zealand, were battling the blaze, contending with temperatures in the high 90s and winds gusting to 25 mph.

The heavily forested area of myriad canyons where the fire is spreading has few roads or natural barriers that can serve as firebreaks or offer havens for firefighters to battle the flames head on, Cal Fire Battalion Chief Jonathan Cox said.

So firefighters instead fell back to natural barriers such as streams or used bulldozers to cut fire lines.

But the flames were moving so fast in spots, they blew past fire lines, forcing firefighters to retreat, Cox said.

“There’s no way you’re going to stop that fire,” said Kyle Coleman, 28, who returned to his childhood home last week to help his father try — in vain, it turned out — to protect it. “A big wall of flames came over the mountain.”

In all, 14,000 firefighters were battling blazes across California, which is seeing earlier, longer and more destructive wildfire seasons because of drought, warmer weather attributed to climate change, and the building of homes deeper into the forests.
