Dangerous situation looms for the Northwest as intense winds could spread ongoing and new fires out of control
A rare fire weather setup this weekend could fuel explosive wildfire growth across the Pacific Northwest after nearly 2 million acres have already burned.
Wildfires continue to rage across the Pacific Northwest
FOX Weather Meteorologist Jane Minar analyzes the persistent wildfire threat across the Pacific Northwest, where more than 1 million acres have burned before the climatological peak of fire season in August. A dry cold front is expected to exacerbate conditions for already-raging wildfires, while smoke continues to degrade air quality across the region.
NORTHWEST – A historic wildfire season is already gripping the Pacific Northwest, where nearly 2 million acres have burned. Now, conditions could deteriorate rapidly in the days ahead as powerful winds threaten explosive fire growth, prompting warnings of a "particularly dangerous" stretch of fire weather.
July has been an explosive month across the Pacific Northwest, with massive wildfires scorching the region. While the area continues to grapple with active fires, conditions are expected to become even more dangerous as a dry cold front ushers in powerful winds capable of driving rapid, explosive fire growth.

According to the National Interagency Fire Center, more than 50 large wildfires, each exceeding 100 acres, are actively burning across Washington, Oregon, Idaho and Montana. Together, they have scorched more than 1.9 million acres, with Oregon alone accounting for 30 of those fires.
LIGHTNING-SPARKED WILDFIRES SCORCH THE NORTHWEST
Thousands of firefighters and support personnel have been deployed to battle the blazes, placing a significant strain on the nation's wildfire suppression resources.
Across the U.S., 44,004 wildfires have ignited so far this year, scorching more than 4.8 million acres. Both totals run well above the 10-year-to-date averages of 34,340 fires and 3.63 million acres burned, marking the most active wildfire season at this point in the year since 2022.
Across the Pacific Northwest and beyond, wildfire smoke is degrading air quality, with Air Quality Alerts in effect for parts of the region through Friday. As long as the fires continue to burn, and especially if they grow, more smoke will be generated, allowing poor air quality to persist or worsen.
Rather than bringing much-needed rain, the dry cold front will usher in powerful winds and sharply lower relative humidity, creating an environment that opens the door for rapid wildfire growth.
WHY DRY THUNDERSTORMS POSE WILDFIRE RISKS
Fire Weather Watches have been issued all across the Northwest in advance of what could be dangerous fire days on Saturday and Sunday.
The Rowe Creek Complex is a lightning-caused wildfire complex that ignited on July 15 near Fossil in north-central Oregon. Multiple fires—including the Crosswhite, Brewer and Green Mountain fires—merged into a sprawling complex that has grown to more than 304,000 acres, making it one of the nation's largest active wildfires.

The most dangerous conditions are expected across the Columbia Basin and portions of central and eastern Washington into north-central Oregon, where dry downslope flow off the Cascades is forecast to drive relative humidity as low as 15% to 20% while sustained winds increase to 20–30 mph, with gusts exceeding 45 mph.
The volatile combination has prompted the Storm Prediction Center to issue its highest fire weather outlook: Extreme risk.
To emphasize the seriousness of the forecast, the National Weather Service has issued a Particularly Dangerous Situation (PDS) Fire Weather Warning, a rare alert reserved for the most extreme fire weather conditions, when rapid wildfire growth and spread are expected.
According to the FOX Forecast Center, new fires will grow rapidly and get out of control. Residents in warned areas should be prepared to evacuate if a wildfire breaks out.

The fires already burning in the region are also vulnerable to spreading rapidly and growing out of control under these heightened conditions.
While Idaho, Montana and Wyoming are not tagged with extreme dangerous fire conditions, they will see 25 to 30 mph wind gusts and relative humidity percentages in the 20s and teens.

Unfortunately, Sunday will be more of the same for the Northwest.
Inside Oregon's wildfire fight: Crews battle flames across the state
Dozens of wildfires are scorching Oregon and much of the Northwest, keeping firefighters on the front lines for another grueling stretch. Crews have spent the past week and a half battling numerous blazes, working around the clock to protect communities, homes and critical infrastructure.
Dangerous fire conditions will again be present with the worst overlap of strong winds and dry air expected to be in central Montana, eastern Idaho and western Wyoming.
There are currently more than 40 large fires burning in the region, but by Monday, that number could be much higher.
