Try it on the model viewer A rainfall accumulation map with the 20km grid selected around Manchester and Leeds, catchment boundaries visible faintly threading through the grid squares.

Model comparison works properly on a phone

The three map panes now stay pinned between the key and the player, so you can scrub through the forecast without scrolling away from the maps. Each pane carries its own model and run picker.
