The weather will be unstable Tuesday night into Wednesday and Wednesday day in the region. Météo-France predicts thunderstorms, rain or hail.
The weather promises to be still warm and sunny this Tuesday on the Mediterranean coast. A few clouds could adorn the sky in the afternoon but the mercury will still be high with 33°C expected in the Marseille city, 28°C in Nice or even 30°C in Toulon.
But the weather will turn stormy overnight. While all the departments of Provence-Alpes-Côte d’Azur are put on storm yellow vigilance this Tuesday, other neighbors such as the Gard are already on orange vigilance.
Risks of thunderstorms are already announced in the Alpes-de-Haute-Provence and in the hinterland of Nice on Tuesday afternoon. Lightnings were remembered in the evening before the real arrival of the stormy episode.
In the course of Tuesday to Wednesday, a need will be set up in the department of Bouches-du-Rhône with in particular thunderstorms. Meteo France explains in its latest bulletin, that in “the second part of the night, this rainy-stormy system shifts over the Provence-Alpes-Côte d’Azur region”.
The meteorological institute predicts a weather “still very disturbed in the South-East of the country with heavy stormy rains which continue” this Wednesday. Risks of thunderstorms are indeed expected in the Alpes-Maritimes, the Var, the Hautes-Alpes and the Alpes-de-Haute-Provence.
Precipitation could be intense and sustained, especially in the Bouches-du-Rhône, with strong winds and a risk of hail.
Because of the historic drought that affects the country, the risk of ruin, flooding or mudslide are very present in the department. The soil moisture index being at its lowest, the latter have become almost impermeable. As a result, water enters it with great difficulty.
The city of Sausset-les-Pins (Bouches-du-Rhône) has also activated a crisis unit, the basements or even the airy centers will be evacuated, the town hall told BFM Marseille Provence. Between 70 and 120mm of water could fall in 24 hours while the cumulative rainfall since January 1 is only 61mm.
This unstable weather should not last forever: Météo-France predicts a return to calm with sunny skies on Thursday.
