Well, *some* of the mets have a theory that ‘canes tend to want to go *towards* bodies of land on their east and *away* from bodies of land on their west. Has to do with the axis of the quadrants not being symmetrical.
That’s why some think Dean will brush Jamaica to the north, instead of head-on and some think he will go up the Yucatan Channel and avoid the peninsula to his west.
Overall, ‘canes want to go north to the pole, anyway, if left to their own devices.
Yes, the tell-tale northward turn is inevitable at some point. This particular model may be more intuitive than the others..............
