That was the Eagle Fire in LMU around 1989. There was a full length video that showed the whole event up through the burned FFs being air transported by C 202. The video was a training video used for years as part of a series of near Miss/ fatality fires. Every CDF station at the time was issued the series on VHS tapes. Maybe some exist or have been converted to a newer format.
Heres a time lapse from the Oroville area I believe last year.
As you guys have seen many times fires can make their own weather.

This one appears to have a counter clockwise rotation

Also the one for the canyon fire is rotating clockwise.
This is pretty nuts –
I could think of a few other adjectives to add to that as well based on intelligence and human factors…but interesting fire Behavior for sure!
Our friends in Australia have their versions…
for context
Lessons learned from the loyalton fire were applied here, a tornado warning was not issued because of evacuations taking place do to the fire but national weather service contacted incident command to make them aware.
