A red flag warning was extended until Friday evening as new wildfires ignited and existing fires spread across Oregon.
The warning was extended due to continued hot temperatures, low humidity and gusty winds, and was set to remain in place until 11 p.m. Friday, the National Weather Service said .
East winds often fuel fire growth this time of year, including more severe examples during September 2020 and 2022. These winds aren’t quite as strong, but they have brought fire growth.
Here are the latest wildfire updates across Oregon.
Rail Ridge Fire explodes to 107,371 acres as Gov. Tina Kotek invokes conflagration act
Gov. Tina Kotek invoked the Emergency Conflagration Act for two wildfires in eastern Oregon on Friday. The Rail Ridge Fire, located 7 miles south of Dayville, exploded to 107,371 acres as of Friday morning. It became just the latest in a string of megafires — blazes over 100,000 acres — in eastern Oregon this fire season.
The act was also declared for the Shoe Fly Fire, estimated at 24,188 acres.
The Oregon State Fire Marshal said its mobilizing its Blue Incident Management Team and several task forces to the Rail Ridge Fire in Grant and Crook counties and the Shoe Fly Fire in Wheeler County.
The two fires are being managed by an incident management team from California.
“The conditions we are seeing on the ground are very dynamic with several fires burning in the region and a cold front is expected to pass through. There’s no real relief in the forecast over the weekend and into early next week,” Oregon State Fire Marshal Mariana Ruiz-Temple said in a news release.

Wildfire smoke impacted Oregon’s air quality across the state on Friday, but it's expected to gradually improve over the weekend, according to the National Weather Service.
Air quality declined Friday to “moderate” across the state, “unhealthy for sensitive groups” in Eugene and the Santiam Canyon and even “unhealthy” in Central Oregon and the Cascade Mountains.
The only place with good air quality was the Oregon Coast.
Easterly winds pushed smoke in from fires east of the Willamette Valley, amid extremely hot and dry conditions, which have caused wildfires to grow .
That was expected to change gradually over the weekend. The wind was forecast to shift, pushing the smoke out by Sunday and bringing cooler temperatures, according to meteorologists at the National Weather Service in Portland.
“The smoke should start to thin out (Saturday) and there shouldn’t be much of any smoke left by Sunday (on the west side of the state),” NWS meteorologist Clinton Rockey said.
The smoke was expected to push out as winds turn from coming from the east to coming from the Pacific Ocean and the west. That was also expected to gradually cause fires to mellow as conditions get cooler and wetter.
“The smoke will still be a problem on the east side and central parts of the state, but even there it shouldn’t be as bad because the weather should cause the fires to quiet down a little,” Rockey said.

Fossil Complex established to manage four fires
The Fossil Complex is comprised of four fires in eastern Oregon near the town of Fossil. The fires include the Canyon, Holmes, and Kinzua fires.
