World Rain Radar shows you weather radar doppler observations from multiple sources on a fully interactive map. You can zoom in, pan and search for locations. World Rain Radar uses multiple sources of data, not one map for the whole world. This gives you the most recent data for your location. Therefore, World Rain Radar works best when zooming in to your local area. World Rain Radar uses real doppler observations and only falls back to satellite sourced data for areas without any doppler radars present. Predict the weather with World Rain Radar: see how storms are moving to see if they are heading for you. Coverage: Europe, Scandinavia, USA incl Alaska, Canada, Hawaii, Puerto Rico, Africa, Australia and Asia. Note: shows rain (radar reflectivity), not clouds!
