NEXRAD volume scans, in order, in three dimensions.

Watch a storm come apart.

Other radar apps show you the storm that is there now. BeamWeather plays the whole run of scans, in three dimensions, so you see the core climb and the column dump.

A radar finishes a volume every 4 to 6 minutes. This is a sequence of real scans, held one at a time. It is not video and we won't dress it up as video.

Three things it does that the others don't

The sequence

Every volume the station made, played in order, in 3D. The structure moves.

The wide scope

The whole scan out to 230 kilometres, standing up over the map, with the camera loose.

Warnings

Watch and warning boundaries on the radar, in the Weather Service's own words, pushed when one lands near you.
