I think the fire causes the wind, in some cases. Air rushing in to replace what's sent skyward by the heat of the blaze.
I'm amazed, looking at the areas that didn't burn, that barren country provides enough fuel to feed a fire like this.
That "metal" sign is probably aluminum which I believe melts at around 11 or 12 hundred degrees F.
