At certain times of year, the Dutch weather radar gets a bit confused and starts identifying North Sea wind farms as storms:

(This tends to happen in the summer months when atmospheric temperature inversions reflect the radar beyond the horizon. I think it's also picking up land clutter from the English coast around Skegness, and I suspect also some ships and oil platforms.)

While it's quite fun to see this, it's not very useful from a weather perspective. It would be nice if Windy could hide the Dutch weather radar in areas where the UK Met Office radar is available. I believe the Met Office radar is much better at suppressing wind farm clutter.
