Hi all,
Sorry for being late to this conversation.
Yes, there is a bug with the DWD data wind direction for the wind direction icon. I thought I fix this - maybe I accidentally commented out the code.
Yes, the icon is a wind vector pointing in the direction the wind is going towards. The dot in the middle of the icon is supposed to be you. The idea is that the icon shows both the direction the wind is flowing to (arrow) and the direction the wind is flowing from (where the arrow is in the circle).
There are no wind barbs.
