Firenado (video) & grim new trends in Cal. wildfires

FIRENADO - the new weather phenomenon. California firestorms plus sudden spinning of air, carrying ground elements high in the air.

CBS News explained it:
"The ambient air temperature in the area was close to 110 degrees, "so that air is super fast rising into the atmosphere," Quinn said. 
"You need to think of this as the air being a solid, and if you're taking a chunk of that air, superheating it and rising into the air, it's leaving a void below it," he said.
As more and more air gets pulled in, it begins to rotate. The more air that gets pulled in, the faster the air swirls and the taller it gets.
"Firenados" also pick up burning embers, ash and flammable debris and extend hundreds or thousands of feet in the air. Those embers can then spread out, jumping fire lines and creating new fires away from the center." 
KTVB presented video capture from a police cruise dashcam.
