@MVRedHead If you wanted to update your location, you could try closing the app then opening it again to reload your location. And currently, we can do nothing in terms of GPS location accuracy. I would recommend using high accuracy mode for locations if you're using Android. Also, currently there is no way for Windy to add a predictive radar feature to the service. It would be way to complicated.

@mesalty To remove a favorite just click on the star (or heart depending of the version) near the favorite name or delete it in list of favorites. To add a location by its coordinates (latitude, longitude) enter them in the right format: https://community.windy.com/topic/80/find-location-by-its-coordinates
