Impressive drop (Dropped in NE quad, ended in SW quad)

It actually dropped in the NW Quad, then floated around the eye till it fell in the ocean in the NE quad. Look at the line that is "Highest altitude where wind was reported" and you'll see the coordinates of the drop are in the NW quad.

 

As a side note, I remember a story from Wilma that a dropsonde went around the eye three times before splashing.

That is pretty awesome.

Then are the wind directions incorrect on the dropsonde?  As NW winds at the surface would be the SW quadrant, while ESE winds initially would be in the NE quadrant.

 

Edited to add

 

Highest altitude where wind was reported:

- Location: 21.93N 66.36W

- Time: 1:18:48Z

Lowest altitude where wind was reported:

- Location: 21.86N 66.49W

- Time: 1:25:39Z

 

 

Highest altitude would be where it was released, while the lowest altitude would be where it reached the surface, which is SW of where it was dropped, which would correspond with traveling from the NE quad to the SW quad

WSW of the center, yes. Sorry, my bad, I was thinking relative to the dropsonde, but relative to the cyclone center the absolute directional degrees around was 140° of turning.

Thanks James, didn't catch that at first.

 

I also remember Felix in 2007 had something similar happen when it was undergoing its RI
