DEADLY



                    TWISTER




                     TORNADO






                  A supercell storm can trigger the most terrifying of all
                  weather events—a tornado. This violent, swirling funnel
                  of air extends from the base of a supercell to the ground.
                  It focuses most of the storm’s energy in one small area,
                  generating incredibly strong winds. These spin around a
                  center of extremely low air pressure that acts like a giant
                  vacuum hose, sucking up dust and debris and hurling it
                  high in the air. Some tornadoes are powerful enough to
                  rip houses apart, toss heavy trucks upside down, and
                  even derail trains. Anyone caught in the path of such
                  a storm would be very lucky to survive.

                                               Tornadoes only affect small
                                               areas as they travel across the
                                               country, but they leave long trails
                                               of destruction in their wake, as

                                               Houses that stood in the path
                                               of the tornado were completely
                                               destroyed, whereas areas on
                                               either side of the storm track
                                               remained untouched.
