The rainSPOT shows the precipitation around you. Your current location is in the center. In this example, there is light rain about 10 km northeast and heavy rain 5 km southwest of you. rainSPOT is a simplified weather radar map that works for a 7-day forecast as well. It also indicates spatial uncertainty: If the entire rainSPOT area is solid blue, it is more likely to rain at your location than if there is only a few blue boxes.
The predictability indicates whether you can rely on the current weather forecast. With high predictability, the weather will very likely be as forecast. With low predictability, the weather forecast is uncertain and could easily be wrong. Keep an eye on updates in this case. Predictability is computed by comparing hundreds of forecasts made by national weather services and institutions around the world.
