Monday 30 October 2017 10.30am EuroTempest has released a storm Herwart footprint based on weather station observations.
The storm has caused widespread damage across Germany, Poland and Czech Republic with at least six people reported killed. Rail travel has been significantly disrupted in Germany. The associated storm surge led to flooding in Hamburg, causing three deaths.
The strong winds across central and eastern Europe yesterday were the result of an interaction between two nearby low pressure centres, named (chronologically) Grischa and Herwart by FU-Berlin. As Herwart was the primary driver of the most damaging winds EuroTempest has labelled the system Herwart-Grischa for its storm catalogue.
