A bit off topic but did you see the program last night about the Alabama tornadoes? A guy 60 miles NE of Birmingham was watching on 2 different TVs the tornado that went throught Tuscaloosa/Birmingham and headed his way. He didn't seek shelter because he didn't think it would go near him. He ended up filming the inside of the tornado from his 3rd floor apartment. The tornado must have taken 2 hours to get there, he was watching it on TV, saw it outside and STILL didn't seek shelter. I doubt it ever occurred to him to seek shelter.
Point is, there are people that just refuse to listen to warnings and there's not a thing you can do about it.
BTW-I completely agree with you. A warning is a warning and seek shelter.
