It turns out that "firestorm" isn't just a figure of speech.
In a scene that looks like something straight out of the Book of Revelation, brushfires in Brazil combined with strong wind gusts to spark a tornado of fire. The bizarre weather event trailed flames in its wake as it touched down in the town of Aracatuba and around its surrounding countryside. Aracatuba hasn't seen any rain in three months.
The flames brought traffic to a halt on a nearby road then disappeared. One local citizen caught the fearsome spectacle on camera. You can watch the raw footage by clicking the title headline link above.
