Sometimes these are called “firenadoes” but this one did not have much fire in it. Dust devils and fire whirls can occur on days when the atmosphere is unstable. The heat from what remained of the fire and the solar heating of the blackened ground probably contributed to the phenomenon. It is interesting that after moving to the edge of the lake it still persisted for a while before dying out.
