These thunderstorms should be particularly windy, with gusts that can again locally exceed 100 km / h, or even be accompanied in places by vortex phenomena, indicates the forecaster.

The windy character is added to this agitated weather with strong gusts near the coast of Languedoc-Roussillon, then from midday, in the Rhône valley, where under the strongest storms, 100 km / h can be exceeded. .
Minimum temperatures range from 12 to 16 degrees in the North West, 14 to 19 in general elsewhere, around 20/21 in Alsace, the Rhône valley and up to 23 on the Mediterranean coast.
