Lightening flash contains over 2000 amps, and only need a tenth of an amp to die. Vast majority of energy goes around the outside of the person(through the moisture of the skin(creates steam from the rain/sweat on body which expands tremendously and can cause explosion)) which can leave scars. Can cause cardiac arrest but it"s rare, vast majority survive some may have nerve damage. Electrical charge always goes around the outside of the body (metal) 95% of tornadoes occur in the us tornado alley. 2 radically different air masses continually collide here. Warm moist air from gulf of mexico travels north and cool dry air tumbles south from canada, as they collide they condense in a popcorn dense cloud ascending 60 ft.
