A clear deterioration in the weather is expected in the next few hours, with a risk of strong thunderstorms expected from this evening until the middle of next night. Particularly strong and not very mobile storms are expected, with particular attention paid to the Vidourle sector, between Gard and Hérault. If the stationary character is confirmed, the accumulations of rain could reach 100 to 120 mm in a very short time. Hail and strong gusts of wind are also possible.
Uncertainties persist over the location
There is uncertainty about the location of the strongest and least mobile storms. Indeed, even if the Vidourle sector seems for the moment to be the most exposed by this risk of a less mobile storm, the situation is not fixed and a geographical shift remains possible. In addition, the storm cells will then move towards Provence. Consequently, a large part of the department should be affected by thunderstorms, although their intensity is less.
Vidourle, Gardons and Vistre under surveillance
If the forecast is confirmed, 100 to 120 mm of rain could be reached. Such quantities of water in such a short time could cause urban runoff and a strong reaction of watercourses. The Vidourle, the Gardons d’Alès and Anduze, and the Vistre, are placed under surveillance by the services of Vigicrues, which indicates in its last bulletin that a “rapid rise in water levels could be observed”.
stay alert
Faced with the threat of these storms, it is essential to take all the necessary precautions to ensure everyone’s safety. It is recommended to limit non-essential travel, especially during periods of heavy rainfall. It is also recommended to shelter sensitive objects from bad weather, secure outdoor facilities and check the condition of roofs and structures that may be weakened by strong winds.
