After Hérault, Météo France has also placed Aveyron, Lot, Tarn, Haute-Garonne and Tarn-et-Garonne on orange vigilance for thunderstorms, rains and floods. The Gard changed from orange to red at the end of the morning. Expect “virulent and very precipitating thunderstorms” in the department, warns Météo France.
In recent hours, severe thunderstorms have erupted between Montpellier, Nîmes and the Cévennes. “We have already measured 184 mm in Saint-Dionisy in 3 hours, including 111 mm in one hour,” said the Meteorological Institute. These storms, violent and not very mobile, will last until the beginning of the afternoon and will be accompanied by “strong gusts of wind, hail” and “marked electrical activity”.
The situation should improve in the afternoon. Until then, the prefect urges not to leave home, and not to pick up the children from school. The city of Nîmes has organized itself to provide a lunch for all school children who return home from midday.

According to Météo-France, “these violent storms are likely to cause significant damage locally”, “lives and property can be locally endangered”, floods are possible. “Some disturbances can affect rail transport”.
In Hérault, this “rainy storm” also requires “special vigilance because there is a significant risk of a violent phenomenon”.
On the Midi-Pyrenees side, there is talk of a “risk of virulent isolated thunderstorms this afternoon then a strongly precipitating storm axis to follow from tonight”.
