I believe this is going to be one of the best tornado information sites ever. I already can’t get enough of the cool stuff with this site. I’m 43 years old and I’ve always been so intrigued with severe weather, hurricanes, and winter weather ever since I was 10 yrs old and 5 days before I turned 11. Huntsville, Alabama (Just 70 miles east of where I live) was hit with a devastating tornado on November 15, 1989. That day has stuck with me and I have been hooked on tornadoes and the science behind them ever since. Or maybe it was seeing my older brother scared to death and crying because of the tornado sirens lol. Thanks for making this site.
