There are occasional times in storm chasing when you know something big is about to happen. This was one of them. The birth of the 90 minute, EF4 tornado in Kansas. This tornado had an audible roar right from the get go and shortly after this grew into a quarter mile wide tornado. #simplyadventure #adventureaddiction #Tornado #Chapman #Kansas #supercell #tornadoalley #greatplains #canonusa #sandisk #landscape_captures #jaw_dropping_shots #earthexperience #majestic_earth #discoverearth #natgeotravel #natgeolandscape
