Thats why Arizona and Texas and all points east get Californias storms, days later....Only much more severe.
You may just want to get a hold of the USGs and the University of Wyoming and Montana and tell them of the big mistake they made. Of course I am not sure what you are going to do about all the volcanic ash that in the sediment records of this area.
You might want to read my post again son. Ya see the part where I typed, "The prevailing winds for hundreds of years now have blow west to east".
I don't care what the winds were doing tens of thousands of years ago...I am simply telling you, if it went off today, the chances of the ash blowing east are *extremely* likely..
To prove this, go to any weather satellite site, and fast forward video, and you tell me the direction the clouds are moving...lol...I just looked, and the entire air mass from that region is moving due east towards Chicago.....
Do you take in account the pure blast effect? Do you have any idea of the power of the eruption of a super volcano? On second thought never mind, you are absolutely totally irrevocably RIGHT!
