Weather Underground shows historical hurricanes that passed through the same area as Felix. Interestingly, the majority seem to have turned north. However, today's models are predicting Felix, like Dean, will just run it up the gut. Did the previous ones mostly turn north because of the onset of fronts thanks to the changing season? The jet stream, I have read, has migrated, on the average, further north thanks perhaps to climate change. In the future will there be as a result less deviation from a WNW path than there has been in the past?
Another measure of whether hurricanes are changing might be the number of miles of a track as a function of category.
