Overview

• The German Weather Service issued widespread alerts for Saturday, with peak gusts up to about 110 km/h on North Sea islands and very strong winds in exposed mountains such as the Brocken and the Black Forest.
• Forecasters expect heavy, sometimes prolonged rain in a northwest–southeast swath, with roughly 30 to 45 liters per square meter raising risks of flooding and slick roads from nasses Laub.
• Lower Saxony’s coastal agency warned of a severe storm surge on Sunday of up to about two meters above mean high tide at ports including Emden, Wilhelmshaven, Cuxhaven, Bremerhaven and Norderney.
• Transport impacts began early: the Emden–Borkum catamaran was canceled on Saturday and Langeoog operators cautioned that Sunday morning ferries may be suspended.
• Strong winds and showers spread beyond the coast into NRW, Niedersachsen and Schleswig‑Holstein, with sturmböen also forecast for parts of the Ostsee, Berlin/Brandenburg and high Alpine peaks.
