Map layers
Weather radars send out pulses and measure the echo from raindrops. RainViewer combines the radars that countries share. Coverage depends on which national radars are included: some areas may be empty even when it rains.
Radar shows the present; it is not a forecast.
Light colours = light rain; yellow/orange/red = heavy rain or thunderstorms. Movement between frames shows where the rain is heading.
