Overview
- The Deutscher Wetterdienst has issued a Vorabinformation and heightened warnings that convective activity will peak on Friday with the risk of locally extreme storms.
- Severe hail and storms have already damaged vehicles, roofs and property in northern and southern pockets and emergency services reported surges in calls and deployments.
- Forecasts list key hazards as very large hail up to about 3–5 cm (locally larger), gusts up to roughly 100–130 km/h and short‑term rainfall that can reach tens of liters per square meter with isolated totals near 100 l/m².
- An upper‑level low (Höhentief), strong instability and wind shear favor long‑lived supercells while weeks of dry, crusted soil will force heavy rain to run off and heighten flash‑flood risk from slow‑moving cells.
- Authorities advise people in southern and southwest regions and isolated northern cells to follow local DWD warnings and emergency guidance since the storms may disrupt transport and infrastructure before the weekend cooling.
