Overview

• Germany’s weather service kept a Vorabinformation Unwetter and high‑level alerts in force for the west and southwest, including NRW, Rhineland‑Palatinate, the Saarland, parts of Baden‑Württemberg and Hesse.
• Early Tuesday observations showed extreme totals near Aachen around 100 l/m², with 116 l in six hours reported at Bedburg, triggering flooded roads and local fire brigade deployments.
• The DWD warned of rapid street and basement flooding, aquaplaning and landslides, advising residents to follow official guidance and local updates via channels such as the NINA app.
• Short‑range guidance indicates widespread 30–60 l/m² with local 60–100 l/m² in a few hours, as slow‑moving, convective cells focus west of the Rhine before weakening later.
• A split pattern persists with low ‘Walter’ driving the wet setup in the west and high ‘Nina’ keeping the east initially drier and warmer before showers reach more regions later Tuesday.
