Having analyzed this data, the app shows the current weather forecast and how the weather will be changing during the day. RainViewer has access to the data from more than 1000 weather radars across the world. Tests over the next three years, conducted by the National Weather Service and the Air Weather Service agency of the U.S. It will automatically search the map, allowing you to learn where the rain, snow, or hail was before it reached your areas and where it will be moving.

We are also working on the display of the mix of precipitation types, such as rain, freezing rain, sleet, and/or snow. Rain and snow are shown in blue whereas showers are marked with orange and red, and hail - with pink. The precipitation type is marked with different colors on the map. It is possible to analyze both types of data in order to identify if the storm can cause severe weather. A modern weather radar is mostly a Doppler radar that can detect the motion of rain droplets in addition to the intensity. With the help of a weather radar map, it is also possible to predict where the rain will be moving next and how intense it will be. A weather radar can determine the precipitation type (rain, snow, hail, etc.) and spot its location.

The Weather Radar Map Live page shows areas where precipitation is currently expected.
