In France, the storms affected areas of the Rhone valley to the North-East, and from the Central-West to the Belgian borders.
Meteo France said “These thunderstorms have been locally violent and associated with hailstorms. In the absence of a marked flow, they were not very mobile and the accumulations of precipitations very locally reached 50 mm in just 1 hour.”
Heavy rain flooded some streets and metro stations in Paris, which also saw strong hail storms.
