Ravsar -- perhaps, but not to any large extent. Any backing up to the west of Ivan's remnant circulation would likely result in a slightly more westward motion of Jeanne, as it would be the same ridge controlling the motion of both systems. However, ultimately, I expect Ivan to clear out and recurve...it just may do it in a weird fashion.

The models aren't totally incorrect with a wobbly/erratic motion once inland, but I don't think it will result in any significant motion westward...and probably not at all back southward...and will only be short-lived. The storm essentially stalling is more likely than not, however, and inland flooding is going to be a huge concern, both for the areas that receive a lot of rain from this storm as well as regions further to the south and east as flooded rivers filter down towards the Atlantic and Gulf.
