Danny has become decoupled from his mid and upper level circulation. Right now Danny's LLC is moving along with the lower atmospheric flow which is westward.

Right now, if the shear stays over the system it will be a mixed bag. LLC could form a new system if it survives and gets to a better environment. In effect a split storm, one tropical one sub-tropical. It could dissipate the LLC and were back to weak wave, or new LLC can form in the convection. Either way, nothing happens really until dry air and shear let up.

[Sanibel]

Stalling. Probably prior to right turn. Must be some westerly shear on this.

Stalling. Probably prior to right turn. Must be some westerly shear on this.

It is still moving to the west.

Looks like a new LLC forming with the MLC in the convection (it has all the moisture and inflow and energy) The naked swirl looks to be headed for poofland. Shear looks to be relaxing over teh convective mass judging from the westerly cirrus cloud movements that were previously sheared to the East. The stall of the swirl MIGHT also mean it is trying to stack back up. I don't recall ever seeing that before.
