Layers
Radar is an optional underlay, off by default so the polygons read cleanly.
Alert types
Radar
Velocity is one radar's, out to about 230 km.
Storm cells
Blue is under the alert threshold. Yellow through pink is Significant and above: the bands that can notify you.
A white ring marks a storm rated severe-likely on any hazard: damaging wind, hail or a tornado.
The solid inner cone is the rotation's, capped at 25 min because beyond that it stops being the smaller one.
