What you're seeing is a composite: NEXRAD-style radar mosaics fused with satellite and model analysis, redrawn every few minutes. Color intensity tracks how hard the rain or snow is coming down.
Colors follow the familiar scale: light blue for sprinkles, green for steady rain, yellow-orange for downpours, and red for intense storm cores.
Flip to satellite for the wide shot: daily NASA imagery that shows entire fronts and tropical systems long before they reach radar range. The toggle sits above the map.
