erin? >> all right. tom, please don't go anywhere. i want to bring in bill nye the science guy for your reaction. just incredibly rare. can you give some comparison on how huge that is relative to a typical tornado and what would have possibly made it so wide? >> well, what would make it s wide is more heat energy in the atmosphere and fundamentally if you think of a tornado as being a half mile or three quarters of a mile wide, this thing's about four times that. maybe a little over four times that as wide so as a first approximation, if it's four times as wide and looking at the same area, it's 16 times as much energy. now, the problem is probably somewhat more complicated than that and on the order of two times ten, 20 times as much energy. >> wow. >> in a tornado. and you guys, i appreciate it. everybody's saying it's a rare event. may never see this again in your lifetime. well, if this is the third tornado to go through very
