Incorrect weather forecast
I live in the south of the state of Bahia, Brazil.
In this period, October/November we have had a lot of rain storms, but the forecast was, strangely, wrong.
Windy does not make weather forecasts, but just visualizes weather models data from leading centrers like ECMWF, NOAA, DWD.... So Windy cannot fix what you consider incorrect.
Have you tried the different weather models that Windy offers in your country? Some could be more performing in your area than the others.
