As mentioned in our previous weather reports, the weather is deteriorating this Tuesday, November 5 in Occitania in certain departments. More particularly in the coastal zone, between the Roussillon and the Languedoc. And risk of thunderstorms should be watched in the late afternoon and evening. Here is the latest weather forecast.
From the beginning of the afternoon, showers increase on the coastal fringe of the region. Over time, the air mass destabilizes. A very strong instability is present in Mediterranean Sea. A light south to southeast wind will bring humidity to coastal areas. Inland, the wind will be oriented north to northeast. Thus, this convergence of winds, among other things, should form potentially heavily rainy thunderstorms. However, doubt remains about their location.
Risk of accumulations of 50 to 80 mm in a short time
Will they hit coastal areas or stay a few kilometers offshore? The latest forecasts suggest that the coastal plains of Aude and theWest of Héraultas well as those of Pyrenees-Orientalescould be hit. Consequently, it is possible to observe rainfall accumulations of 20 to 50 mm in one hour only and 50 to 80 mm in less than 3 hours. Caution will therefore be required if these storms were to form in these urbanized areas.
This risk of storms will continue into the early evening, before fading during the next night, possibly quite late on the coast of Roussillon. Note that this is just a risk. As stated above, it is entirely possible that these storms will remain in the Mediterranean and only marginally affect our departments. It will be necessary to follow their live evolution with radar images, available on the mobile application InfOccitanie. We will keep you informed of developments.
The areas between Perpignan, Leucate, Narbonne, Béziers and Agde are particularly exposed (Corbières maritimes, Biterrois, Minervois, etc.). Overall, all of the coastal plains of these three aforementioned departments can experience heavy rain and thunderstorms. Stay informed of weather developments.
