This might be because I am senile, but I can't recall, in past years, having quite the dramatic changes in the models, and forecast tracks, that we have been seeing this year ie. Charley, Frances, Ivan. Is this because we are trying to forecast further in advance (I think the "official 5-day track" is a relatively new thing?), or is it because each of these storms has had its own set of more complicated than usual weather parameters in which to move?

OR, is it like when you forget the pain of a traumatic event, I just don't remember the roller coaster rides of previous years? :?:
