Word of the day: firenado

A firenado is a torrent of wind and flame that burns at extreme temperatures. Such whirlwinds form when a fire heats air above it and pulls in cool air at its base, creating a self-sustaining vortex.

The most likely location for such a terrifying phenomenon is the United States and Australia and, in the last few days, there have been some extremely large firenadoes in California.
