Tornadoes get my vote for scariest weather event/natural disaster. I'm probably biased because I live close to Tornado Alley. Nevertheless, they look like a great howling demon from hell, and if they hit a town it's basically like it got blown up by a bomb. Not a fan, really.
I made a pair of "Braille Gloves" which have 6 vibration motors in six finger tips and vibrate in the relevant patterns. I have used this to read stuff while out walking. Given there is a fairly well defined programmer-oriented Braille encoding I should imagine it would work in this situation. Diagrams could be a pain still.
Note: I am not blind but have learnt Braille fairly easily so for me it works quite well
Disclaimer: I haven't tried this while driving yet...
