These bad weather conditions may "extend into the night from Friday to Saturday" and therefore require special vigilance.
"Follow safety instructions"
"Be extremely vigilant in your travels, respect the safety instructions," warns the prefect of Hérault on Twitter. The location of the strongest storms "is still uncertain, they can occur on the Haut Languedoc or rather towards the plains," warns Météo France.

This change in weather is caused by the Oscar Depression from the Atlantic, which interacts with warm air on the surface in France.
In addition to Gard and Hérault, 55 departments are on yellow alert for thunderstorms and 7 for floods, mainly in the west of France.
