For Hainburg in central Hessian valley, the key weather variable isn't a daily percentage — it's exactly when a cell crosses the Lahn (Rhine tributary) catchment and how fast it tracks toward your location.
Hessen forecasts cover a lot of ground. In Hainburg, knowing whether the cell is crossing the Lahn (Rhine tributary) upstream or downstream from you is the specific detail that matters — and only the radar shows it.
RainViewer uses Germany's DWD radar network — 17 dual-polarization Doppler stations with 5-minute scan cycles — to show Hainburg's rain in real time. The Lahn (Rhine tributary) catchment, the surrounding central Hessian valley: all visible as it develops.
**Transition months** The spring shoulder (April–May) sees Hainburg's Lahn (Rhine tributary) catchment still saturated from winter, making it more responsive to rainfall than the bare figures suggest. Autumn (September–October) brings the reverse pattern: summer-dry soils that absorb the first rains, then flood risk that builds through October.

A radar check before setting out shows the 90-minute weather window — enough to decide whether to start the route or wait for the cell to clear.
**Hainburg web users going mobile** Attribution data shows Hainburg web visitors installing the Android app — the same radar they checked online, now available as a push alert before rain crosses the Lahn (Rhine tributary) catchment.
