Rain Radar

Add real-time and forecast rainfall overlays directly into your ArcGIS® Experience Builder apps. The Rain Radar widget integrates with Rain Viewer to show animated radar imagery on top of your existing maps. It is perfect for planners, responders, and field teams who need fast, visual insight into weather conditions as they evolve.
