Would my safe room be safe in a tornado?

That Depends on the Strength of the Tornado- AND whether your House took a Direct "Hit" or Not !!! Here's the "Problem" ; Assuming your "Safe Room" is above ground, -It could be all too vulnerable- to the Sudden plunge of Atmospheric Pressure that occurs- as the Twister is passing Overhead! What THIS Does- is to turn the area AROUND your House into a "semi-vaccuum", and EXPLODE your "safe room" outward because of the MUCH higher pressure INSIDE it !!! And once your "Safe Room" is Gone, -You're Next !! So there are NO Guarantees :o
