![]() ![]() If the radar animation of the last hours shows local thunderstorms or precipitation cells forming and disappearing in an irregular manner, then the forecast is not vey accurate. The forecast works very well when weather fronts or large organized precipitation structures are moving regularly, without disappearing or being created. Real weather is more complex than just the displacement of existing precipitation cells. Data on this map is incompatible with screen readers - please refer to the weather symbols map for an. Also details how to interpret the radar images and information on subscribing to further enhanced radar information services available from the Bureau of Meteorology. Longer forecasts are not possible, as new precipitation cells are developing or existing ones are disappearing within a short time. Provides access to meteorological images of the Australian weather watch radar of rainfall and wind. This so called precipitation nowcast is the most accurate precipitation forecast possible but the forecast horizon is limited to about an hour. The rain/snow forecast is computed by estimating the movement of precipitation cells observed by radar and extrapolating this movement into the future. Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation. Groningen: How accurate is the radar based forecast? Moreover, some countries do not operate a weather radar network, and in those countries satellite data is used to estimate rainfall, which is less accurate than a realtime weather radar. Note that lightning is not shown on the forecast, as it cannot be predicted. Light blue indicates drizzle, blue a medium intensity, and red and yellow indicate very strong precipitation, usually associated with thunderstorms.Ĭurrent lightning strikes are marked with small orange dots on the map (Europe only). The different colours indicate the intensity of rainfall or snowfall. The radar map is updated every 5 minutes with a new radar observation. The weather radar ( Groningen) shows where it is currently raining or snowing. See the latest India Doppler radar weather map including areas of rain, snow and ice.
