OK...let's try this a third time.

Will you guys stop with the wobbling, the northerly motion, etc.

The hurricane is simply oscillating along the (curved) track, which can be clearly seen by the satellite images. And, it is totally on the forecast points.

So...go to the floater, select the wv loop, select the 1845Z image. Now, zoom in a couple times on the eye. Locate a point on the western side, just north of due west, about 300deg (just below where the eyewall stops touching the Yucatan peninsula. Now, move forward four more frames, and watch the rotation of the eye around this point on the eyewall. That's an oscillation. Go back and forth over those five frames and you'll see it better.

Now, zoom out to verify you are at frame 2045Z. Zoom back in. The point of rotation now moves up to just a fraction above the previous one, just above where the SW eyewall stops touching the Yucatan peninsula. Again, move forward four more frames, backward and forward, and now you see that oscillation.

Now you're at 2245Z. This time, the rotation is around the westmost point where the eye meets the Yucatan peninsula (because these oscillations are occuring on a curve, not a straight line). Now move forward three frames, and back, and you can see the third oscillation (up to frame 0015Z).

Sorry but typed in wrong starting point...1815Z is at the end of the prev osc.
