I recall from reading previous posts that there is sometimes an elongation in the direction of travel as a hurricane is beginning to turn. As I've been watching the model runs such as NOGAPS over the past few days they seem to confirm that this elongation does occur when the show their turns (is that correct?)

Does it appear to anyone else that there is this type of elongation beginning to occur in the last portion of the IR loop? It also seems like there is a bit of a more northerly component in the last frames of the floaters. This may just be more stairstepping...
