Overview
- The German Meteorological Service (DWD) issued high‑level warnings on Wednesday for parts of southeast Bavaria, elevating several districts to Warnstufe Rot for severe thunderstorms with heavy rain, hail and storm gusts.
- Thunderstorms produced very heavy, localized rainfall of about 20–50 liters per square meter in short periods, small‑grain to golf‑ball hail and gusts commonly around 70 km/h with isolated gusts near 100 km/h, creating flash‑flood, fallen‑tree and aquaplaning hazards.
- The DWD named specific counties under warning including Weilheim‑Schongau, Miesbach, Rosenheim, Lindau, Oberallgäu, Ostallgäu, Garmisch‑Partenkirchen and Berchtesgadener Land where Alpine lift (staulagen) can amplify totals.
- Northern and coastal Germany saw a separate rain and wind band from the North Sea with rising coastal winds and possible strong gusts, while forecasts call for a brief easing on Thursday before new rain fronts return later in the week.
- Longer‑range outlooks show the southwest and the Rhine corridor remaining unusually dry through late September, a pattern that could lower Rhine levels, restrict barge loads and raise inland shipping and fuel costs for consumers.
