Overview
- National and regional weather services issued multiple active warnings on Thursday that covered parts of Germany, with the Deutscher Wetterdienst confirming a tornado in Brandenburg and upgrading some Bavarian areas to Warnstufe 3 for very strong storms.
- Local DWD alerts for counties such as Diepholz and Rotenburg warned of life‑threatening lightning, heavy hourly rainfall, hail and gusts up to about 80 km/h and advised people to seek shelter and avoid flooded roads and underpasses.
- Italian civil‑protection agencies declared Orange alerts for Lombardy and parts of northern Italy as models forecast extreme, localized Alpine rainfall that in some runs could reach roughly 200 liters per square metre, raising flood and landslide risk.
- Operational forecast models now diverge: some deterministic runs (ICON/GFS/ECMWF variants) project a Scandinavian high that would push temperatures back toward 30–35°C, while alternative runs show a Vb‑type or Atlantic frontal resurgence that would keep conditions cooler and wetter into early September.
- The immediate human risks are flash floods, infrastructure and crop damage, travel disruption and wind/hail losses, so officials urge people to secure loose objects, avoid open water and follow local warnings as model uncertainty will determine which broad pattern unfolds next.
