The first vortex appears.
This is shot by an emergency team as fire fighters watch in disbelief. Fire fighters have died in these events before.

AND THE WIKI SAYS (To be taken with some reserve):
A fire whirl is a phenomenon in which a fire, under certain conditions (depending on air temperature and currents), acquires a vertical vorticity and forms a whirl, or a tornado-like effect of a vertically oriented rotating column of air. Fire whirls may be whirlwinds separated from the flames, either within the burn area or outside it, or a vortex of flame, itself.

A fire whirl can make fires more dangerous, an extreme example is the 1923 Great Kantō earthquake in Japan which ignited a large city sized firestorm and produced a gigantic fire whirl that killed 38,000 in fifteen minutes in the Hifukusho-Ato region of Tokyo.[1] Another example are the numerous large fire whirls (some tornadic) that developed after lightning struck an oil storage facility near San Luis Obispo, California on April 7, 1926, several of which produced significant structural damage well away from the fire, killing two. Thousands of whirlwinds were produced by the four day long firestorm coincident in an environment that produced severe thunderstorms, in which the larger fire whirls carried debris 5 kilometers (3 mi) away
