The "Bootleg fire" in Oregon's at the video, but hundreds of fires are blazing across the American west. 

At the New York Times, "How Bad Is the Bootleg Fire? It’s Generating Its Own Weather":

A towering cloud of hot air, smoke and moisture that reached airliner heights and spawned lightning. Wind-driven fronts of flame that have stampeded across the landscape, often leapfrogging firebreaks. Even, possibly, a rare fire tornado.

The Bootleg Fire in Southern Oregon, spurred by months of drought and last month’s blistering heat wave, is the largest wildfire so far this year in the United States, having already burned more than 340,000 acres, or 530 square miles, of forest and grasslands.

And at a time when climate change is causing wildfires to be larger and more intense, it’s also one of the most extreme, so big and hot that it’s affecting winds and otherwise disrupting the atmosphere.

The Bootleg Fire has been burning for two weeks, and for most of that time it’s exhibited one or more forms of extreme fire behavior, leading to rapid changes in winds and other conditions that have caused flames to spread rapidly in the forest canopy, ignited whole stands of trees at once, and blown embers long distances, rapidly igniting spot fires elsewhere.

“It’s kind of an extreme, dangerous situation,” said Chuck Redman, a forecaster with the National Weather Service who has been at the fire command headquarters providing forecasts.

Fires so extreme that they generate their own weather confound firefighting efforts. The intensity and extreme heat can force wind to go around them, create clouds and sometimes even generate so-called fire tornadoes — swirling vortexes of heat, smoke and high wind.

The catastrophic Carr Fire near Redding, Calif., in July 2018 was one of those fires, burning through 230,000 acres, destroying more than 1,600 structures and leading to the deaths of at least eight people, some of which were attributed to a fire tornado with winds as high as 140 miles per hour that was captured on video...
