I’m not a wildfire expert, but this has to be unprecedented. Here is an animated GIF of the wildfires from the afternoon of the 7th until the morning of the 9th.
At the start of the animation, you can see the Lionshead fire smouldering. Overnight on the 7th/8th the cold front passes and the fires just explode westward. Major fires erupt in the McKenzie, Umpqua and Clackamas drainages as the Beachie fire above Opal creek rapidly expands and is caught by the Lionshead.
Stay safe everyone.
