Wildfires in California and Oregon

Wildfires in California wine country and Central Oregon grew overnight, prompting hundreds of evacuations as firefighters sought to contain the blazes Sunday amid dry, hot weather.

The Pickett Fire in Napa County had grown to more than 10 square miles and was 11% contained as of early Sunday, according to the California Department of Forestry & Fire Protection.

About 190 people were ordered to leave their homes, while another 360 were under evacuation warnings as the fire threatened about 500 structures near Aetna Springs and Pope Valley, said Jason Clay, spokesman for Calfire Sonoma Lake-Napa Unit.

Firefighting Efforts

More than 1,230 firefighters backed by 10 helicopters were battling the fire, which began Thursday after a week of extremely hot weather. The cause of the fire is still under investigation.

Residents of the Western United States have been sweltering in a heat wave that hospitalized some people, with temperatures forecast to hit dangerous levels throughout the weekend in Washington, Oregon, Southern California, Nevada and Arizona.

Clay said the weather has moderated since the fire broke out, with Sunday’s high expected to be 94 degrees. But humidity levels were expected to drop amid increasing winds later Sunday afternoon.

“That’s been a driving factor in the afternoons since we’ve seen the fire activity pick up for the last three days,” Clay said, adding that “support from all up and down California has been critical to our efforts.”

Comparison to Previous Fires

The fire began in the same area as the much larger Glass Fire in 2020, which crossed into Sonoma County and eventually burned about 105 square miles and more than 1,500 structures.

That fire was driven by wind, while the current fire is fueled mainly by dry vegetation on steep slopes — some of it dead and downed trees left over from the Glass Fire and some of it grass and brush that grew back and then dried out again, said Clay.

Oregon Wildfires

In Oregon, the Flat Fire in Deschutes and Jefferson counties had grown to almost 34 square miles, with about 4,000 homes under various levels of evacuation notice, including 1,000 with orders to leave immediately, according to the state Fire Marshal’s Office.

Firefighters were able to cut containment lines and continued to suppress fires in some residential areas. However, they faced significant challenges Sunday with difficult terrain, low humidity and triple-digit temperatures in some areas, officials said.

Some homes have burned, and officials said they were working to confirm the status of structures.

The area is in a high desert climate, where dried grasses and juniper trees are burning and fire is racing through canyon areas where it’s challenging to create containment lines, said Jason Carr, Deschutes County sheriff’s spokesman.

Weather Conditions

The fire began Thursday night and grew quickly amid hot, gusty conditions. Fire officials were keeping an eye on isolated thunderstorms in Southern Oregon that could drift north on Sunday, state Fire Marshals spokesman Chris Schimmer said in a video posted to Facebook.

“If we get thunderstorms that roll through, it can … cause the fire to jump (containment) lines,” said Carr, adding the downdrafts can push fire in multiple directions.

Climate Change and Wildfires

Although it’s difficult to directly tie a single fire or weather event directly to climate change, scientists say human-caused warming from burning fossil fuels like coal and gas is causing more intense heat waves and droughts, which in turn set the stage for more destructive wildfires.

Conclusion

The wildfires in California and Oregon are a reminder of the importance of being prepared for natural disasters and taking steps to prevent them. The dry, hot weather and strong winds have created a perfect storm for wildfires to spread quickly, and it’s essential for residents to follow evacuation orders and take necessary precautions to stay safe.
