World precipitation forecast
Explore the world, find a city and play stored three-hour forecasts. The map, location series and CSV come from the GOMD database.
DWD ICON GLOBAL · 3-HOUR TOTAL
World precipitation map
Approximately 13 km native model cells · mm / 3 hours · UTC
REQUESTED INTERVAL · DB TIMELINE
Times are UTC interval ends; each frame shows the preceding three-hour total. Playback stays within the selected model run. Soft transitions are visual only; they do not create intermediate forecasts or observations.

STORM FORECAST AND ACTUAL OBSERVATIONS

Waiting for the matching precipitation frame.
Contains modified EUMETSAT Meteosat LI L2 Lightning Flashes · CC BY 4.0 · NOAA GOES GLM
⚡ Storm expectation · symbolic animation✦ Observed satellite flash · actual time order
ICON weather codes forecast hourly thunderstorms; available hours of the three-hour interval are shown together and missing hours are reported. A blinking storm symbol is not the time or position of an actual lightning strike. GOES GLM observes the Americas and adjacent oceans; EUMETSAT MTG LI observes Türkiye/Europe, Africa and part of the visible satellite disc. These are not a worldwide lightning network and do not distinguish ground strikes alone. Each source shows its actual DB import status; missing imports do not mean no lightning. Observation playback plays the selected three hours in 12 seconds, then repeats after a short pause; observations are never added to future intervals. Reduced motion keeps symbols static.

At world scale, native ICON cells in the DB are binned for display; zooming uses native model detail. Smooth view blends colours between valid neighbouring cells only. Location queries and CSV preserve native DB values. Not-yet-imported or source-missing areas are not zero rainfall; smoothing never fills them.
Leaflet · Natural Earth · Terrain, boundaries and place names are visual references. The Mercator map is limited to ±85.05°; polar cells remain available through coordinate queries.

When comparing, check three-hour precipitation, model, UTC interval and model run time. Forecasts may differ.
Three-hour time series
Each bar represents an actual forecast interval; missing intervals are never filled with zero. All timestamps are UTC.
| Start → end (UTC) | Total (mm) | Status |
|---|
Source and method
Native triangular cells and model run metadata from DWD ICON Global are stored in the database. Each three-hour total is the difference between source accumulated precipitation at the interval start and end. This is a global forecast over land and ocean, not a station measurement.
Native cells are approximately 13 km in scale. Timestamps are UTC interval ends; totals cover the preceding three hours. Location queries read the nearest imported native model cell; the raster image is for visualization only.
Persistent archive and freshness
Only ingestion jobs request provider data. User queries and CSV downloads read the GOMD database; missing values never trigger an external request. Model run time, retrieval time, missing intervals and actual DB record counts are displayed separately.
