Thanks for looking into it. I appreciate seeing the different wind patterns at different altitudes. We had a large tropical storm over our region in southern Maurtiania last night, while your app showed no rain. This morning we had clear skies and your forecast told me it was raining hard. I don't know anything about the science of weather prediction, but I appreciate your efforts :)
Pleased that @idefix37 was able to additionally explain things for you.
Also, to clarify further, Windy does not create any forecast data but instead only visualises forecast and actual data received from various third party providers.
For Africa this includes ECMWF and GFS for forecast data, and EUMETSAT for satellite images.
There is no forecast created by Windy.
