Rain radar and weather in Lombardy
Explore observed rainfall across Lombardy over the past 24 hours and compare it with ICON-2I precipitation forecasts up to 72 hours ahead, when available. You can also view temperature, hourly rainfall, humidity and wind measured by ARPA weather stations. Each reading displays its own observation time.

From observations to the next 72 hours
The timeline separates observed radar frames from ICON-2I forecast frames. If the model is unavailable, the map keeps the observations and reports that forecast data are missing. We do not display unsupported weekly forecasts or future temperatures.

Rainfall in Lombardy: radar observations and ground measurements
Radar colours show the strength of observed precipitation echoes, not millimetres of rain measured at every point. Select Rain on the ARPA weather-station layer for available hourly ground totals. Weather-station measurements may be older than radar frames: check the timestamp of each reading.

The timeline separates past observations from rainfall predicted by ICON-2I. The Radar cells layer can display short-term estimated motion and indicative arrival times for municipalities. These estimates are not official warnings and may be unavailable if tracking is unreliable.
