Those are only predictions... although I do certainly share some of that fear. It's bad enough to mess up our own coast but if some of that does end up floating around in the swirlies/mucking up other shores, we'll have to figure out how to tell our grandkids how and why that happened.
I'm just gonna keep these fingers crossed.
[EDIT]
From the looks of that image, Canada will be safe at least. *bonus*
