Volcanic rain. Sudden windstorms. Twin tornadoes.  They are strange and rare weather events...but they do happen.  Avid hiker and backpacker Benjamin Earwicker is almost taken down by wind and dozens of falling and uprooted trees; extreme explorer George Kourounis is almost burned to death when acid rain caused by an erupting volcano falls down on him and burns through his gear and clothing; Tornado Alley bank President Gene Willers risks his life for his staff, shutting them in the bank vault as his bank gets levelled by Twin Tornadoes. Experts explain the science behind these one-of-a-kind rare weather phenomena.
