Estimated current conditions and a seven-day forecast from DWD ICON global, not weather observations. The first 24 hours can be selected hourly; after that, forecast slots are six-hourly when official model data are available. Now checks for new data every 30 minutes. Icons follow the forecast selected, with no interpolation between weather categories. Zooming changes symbol density, not model resolution. Accumulated rainfall and new snowfall only cover the stated future window (up to 3 or 6 hours, not beyond local midnight). If model data cannot isolate that interval, no misleading total is shown. New snowfall in cm is approximate (water equivalent, 10:1 ratio). Sun and moon are calculated for each location and valid time.
