Red and orange vigilance lifted for the Gard and the Héraut this Tuesday afternoon. Twelve departments in the Center and the South of France are now in orange, for the risk of thunderstorms, rain and flooding.
The rainy-thunderstorm episode began this Tuesday morning, at 8 a.m. in the Gard and the Hérault. Severe and very localized thunderstorms are expected, with rainfall ranging from 80 mm to 100 mm or more in a short time. Strong gusts of wind and hail are also expected until midday. In the Midi-Pyrénées, the risk of virulent isolated thunderstorms is expected this afternoon, until this evening.
At 4 p.m., twelve departments in the Center and the South of France were placed on orange vigilance. Six new departments, Creuse, Haute-Vienne, Puy-de-Dôme, Corrèze, Cantal and again Hérault were added to the first six departments, Gard, Lot, Tarn-et -Garonne, Haute-Garonne, Tarn and Aveyron.
At 11:35 am this Tuesday morning, the Gard was placed in red vigilance. Since the beginning of the afternoon, this red vigilance has been lifted. Then the orange vigilance of the Hérault was also lifted. Six departments in the South of France remain vigilant orange: Gard, Lot, Tarn-et-Garonne, Haute-Garonne, Tarn and Aveyron.
The Minister of the Interior Gérald Darmanin is going this Tuesday afternoon in the Gard, following the violent thunderstorms. Two people are wanted after the violent storms that hit the Gard on Tuesday: a man is wanted in Uchaud, a woman in Aigue-Vives.
In the Gard and the Hérault, since the end of the night from Monday to Tuesday, strong thunderstorm cells have been triggered over an area ranging from the Montpellier and Nîmes regions to the Cévennes. Accumulations of 150 mm in three hours were measured at Quissac. In some areas, the estimated water depth exceeds 150 mm.
This rain and stormy situation will continue throughout the morning in the Hérault and Gard. The most affected areas are the Gard and the north of the Hérault. These storms are locally violent and not very mobile, in particular on the first reliefs of the Gard. They can give 80 to 100 mm in a short time.
Strong gusts of wind, hail and marked electrical activity are also expected. The expected accumulations could locally exceed 200 mm. Thunderstorm activity will subside from the west.
In the Lot, Tarn-et-Garonne, Haute-Garonne, Tarn and Aveyron, the active rain-storm episode requires special monitoring given its persistence and the associated accumulations. From the middle of the afternoon, the situation will become very unstable with the outbreak of thunderstorms first over the Haute-Garonne and the Tarn-et-Garonne then moving east to reach the Lot, the Tarn and Aveyron at the end of the afternoon.
These storms promise to be isolated, but they will be potentially virulent with very high hourly intensities that can reach 30 to 40mm in 1 hour and sometimes intense hailstorms. These thunderstorms circulate in the flow, but can follow one another, thus bringing locally up to 70mm in 3 hours.
After a short lull in the evening, a new stormy pulse will gain by the Pyrenees in the first part of the night and spread rapidly northward to affect all of the east of Midi-Pyrénées in the form of particularly rainy thunderstorm clusters. Under these thunderstorms, precipitation is often expected to be heavy and occasionally very heavy with hourly accumulations that can very locally reach 50mm.
