After the remains of ex-Hurricane Kirk, here are the remains of Leslie. If the weather context will not be the same with an arrival in the south of the Iberian Peninsula, the result will be similar this week in France: more rain.

And sometimes in very large quantitiesin the south of the country.

A marked episode of Mediterranean rains and thunderstorms

From Tuesday October 15 in the evening and especially on Wednesday October 16 and Thursday October 17, 2024, very significant precipitation should occur in the Cévennes and affect the departments of Hérault, Gard and Ardèche.

This episode of Mediterranean rains will eventually reach the Provence-Alpes-Côte d’Azur region. And at the same time, storms will appear and cross France from West to East on Wednesday and Thursday, with this powerful southwest altitude forcing.

This, before a gale in the northwest quarter of the country already anticipated by the weather models for this Friday, October 18.

Rising temperatures…

A hectic week on the weather front, again, we tell you. “Ex-Hurricane Leslie, loaded with tropical air, as it moves back towards Portugal, will cause a shift in the flow to the South at altitude and at low levels, at the start of the week in France,” explains to actu.fr meteorologist Yann Amice.

This will lead to a rise in temperatures, but also the return of high humidity to the south of France, accompanied by atmospheric instability and powerful storm developments. Then, a windy and rainy depression will arrive from the west by Friday.

This disturbance will also bring accumulations of rain which could become significant between Friday October 18 and Saturday October 19, 2024 over a large part of the country. And this, in places, on soils already saturated with waterwhich could raise fears of further flooding. Before an improvement. Finally.

…and air “very heavy with humidity”

If ex-Hurricane Kirk, which came from the Atlantic last week, landed directly on the country, the scenario will not be the same with Leslie.

This ex-cyclone landed much further south, but it is once again an air very laden with humidity, which will concern France and in particular the Cévennes sector.

Wednesday October 16, 2024, a rain-storm degradation will affect the western half of the country bringing moderate precipitation to already saturated areas. Cévennes rains will also begin. Thursday, October 17, the rainy axis will shift further east, becoming more stationary. The rains will often be moderate and even locally heavy, from the Pyrenees to Burgundy via the Massif Central. In the Cévennes, heavy rains will continue all day, they will spread to a large south-eastern quarter, as far as the Alpes-Maritimes.

Ex-Hurricane Leslie (which will end up near Portugal) will bring up the air very soft, but very loaded with humidity. At the start of the week, temperatures will be well above seasonal norms, sometimes even more than 25°C in the South-West.

In the wake of Kirk, a major hurricane, Hurricane Leslie (now an extratropical storm), less powerful, reached stage 2 out of 5 last Thursday in the middle of the Atlantic.
