Weather Circle

Weather Circle is a live severe-weather command center: professional-grade radar, satellite, and instant alerts — plus a real community of storm watchers and chasers on the same map.

When weather turns dangerous, seconds matter. Weather Circle streams warnings the moment they're issued, paints them over live radar, and puts you on the map with everyone else tracking the storm.

• Smooth radar animation with multi-radar mode — watch several sites sweep in sync
• Automatic storm-motion detection and velocity de-aliasing, the kind of processing serious radar tools charge for
