WEATHER – Severe thunderstorms and record rains hit the Gard on Tuesday, September 14, where one person is missing. Météo-France continues to call for caution in the sector, with “strong thunderstorms” still expected this Wednesday, September 15.

“A person is missing in the town of Aimargues after a fall in the Rhôny river”, southwest of Nîmes, the Gard prefecture said on Tuesday evening in its latest press release.

Before this person, two others had been temporarily missing earlier in the day, in Aigues-Vives and Uchaud, two localities close to the A9 motorway connecting Nîmes to Montpellier. One “was found”, specified the prefecture at the end of the afternoon, adding that the research and testimonies on the second wanted person led, “at this stage, to rule out the hypothesis of disappearance”.

A lightly injured person struck by lightning

So far, no casualty, except a “lightly injured” struck by lightning, has been officially reported in the department.

Come to meet the emergency services and the authorities on the spot, Tuesday evening, the Minister of the Interior Gérald Darmanin warned about the following events: “We are particularly vigilant in the Hérault and the Gard, where we fear other episodes of this type in the hours and days to come ”.

The situation “will deteriorate again from tonight,” the prefecture confirmed, announcing that “public and private schools will remain closed on Wednesday”.

The Gard went back to orange vigilance for thunderstorms, rain-floods and floods on Wednesday morning: “We expect strong rainfall intensities of the order of 80 to 100mm in a short time locally for Hérault and Gard, 50 to 80mm for the Ardèche and Drôme ”, Météo France notes in its 8am bulletin on Wednesday September 15th.

The organization has placed a total of four departments on orange vigilance for thunderstorms: Ardèche, Drôme, Gard and Hérault.

The stormy wave that has affected a large part of the south of France since the start of the day has been particularly active in the Gard, where it has affected around sixty municipalities. The department was placed in red vigilance between 11:30 am and 2 pm, and in particular around Nîmes, where the roof of a shopping center has partially collapsed.

“The impression of a wave”

The Minister of the Interior described “very exceptional, very concentrated and very unpredictable circumstances”.

“Nothing foreshadowed an event of such magnitude”, had confirmed in the afternoon Marc Pontaud, expert of Météo-France: “244 mm in three hours in Saint-Dionisy, it is something exceptional ”, He insisted, recalling that the absolute record in the Gard was until then 216.4 mm in Saint-Martial on September 19, 2020.

In the village of Aubord, many ground floors were flooded, but without significant damage, testified the mayor André Brundu to theAFP: “Fortunately we still have somewhere in our misfortune to have two large retention basins that have played their role, it is nearly 460,000 m3 of water that have been retained”.

“It went up suddenly”, noted the village grocer, Christelle Plagnes: “We had the impression of having a wave coming in, it was very impressive”.

It is especially at the level of transport that the disturbances were the strongest and the images most impressive.

While many roads and bridges were cut, the A9 motorway, a major axis connecting the Rhône valley, the Marseille region and Italy to Spain, was closed for several hours. On this highway, “around 30 people were brought to safety by air and land,” said the firefighters, who carried out a total of 60 helicopter hoists and 450 safety operations.

At around 8:00 p.m., the motorway was reopened in both directions, Vinci said, but not on all lanes, with cleaning operations and work still underway.

“Another phenomenon is starting in Midi-Pyrénées, where a hundred millimeters in three hours are expected,” warned Marc Pontaud, according to whom precipitation will again affect Languedoc in the second part of the night: “A priori , we exclude a worst-case scenario for the moment, ”he reassured, however.
