the tornado outbrake in OK...but you belive in F6 tornado in that day?i have read and listen that..
yes, I heard that too...but tell me the difference F5 vs. F6...if wind blows with 300mph or 350mph...would that make any sense?

I've read those tornado scales, is F6 a standard or is just from F0-F5?
