Overview
- The Deutscher Wetterdienst has active warnings for Thursday into Friday forecasting very heavy short‑term rainfall around 15–30 liters per square metre and locally higher, hail up to about 3 cm, and storm gusts up to about 100 km/h.
- Meteorologists expect the first and strongest storms in the south and southwest before a convective band spreads into central and eastern Germany on Friday while the far northwest remains comparatively less affected.
- Emergency services reported significant local damage from mid‑July storms in Baden‑Württemberg, with flooded cellars, fallen trees and temporary power outages that at times affected thousands of households.
- Forecasters stress that slow or stationary thunderstorm cells can deliver extreme local totals of up to roughly 100 l/m², and hard, dry soils from the recent heatwave increase surface runoff and the risk of flash floods in towns and valleys.
- A marked cooling is expected over the weekend with daytime highs falling to the low‑to‑mid 20s, but major weather models continue to show a developing risk of another heatwave at the end of July into early August.
