Parasitic tornadoes typically form near the edge of the main mesocyclone circulation, an area that often exhibits extreme and chaotic shear. Parasitic tornadoes are typically ropelike and much smaller than the main tornado which is normally near the center of the mesocyclone circulation. But parasitic tornadoes can still produce significant damage and either ruin your chase or even worse, end your chase career. While your attention is focused on the main tornado, one of these little devils could sneak up on you when you least expect it. Above all, watch the traffic.
Ordinary people do crazy things when driving near tornadic thunderstorms.
If you chase at night and feel that you've got it figured out, watch out, because I guarantee that you don't. I'd much rather see a storm like this during daylight. All rights reserved. Video of this event is available through Storm Stock .
