# Stormy weather and heavy rain in the South-East and Corsica

> At the beginning of November 2026, thunderstorms are forecast along the Mediterranean coast, with six departments threatened on Tuesday according to Keraunos. Forecasts then indicate nine departments in the south-east affected on Wednesday and a Mediterranean episode with heavy rain until Thursday, with up to 250 mm locally. Météo-France has placed six departments under yellow alert for thunderstorms and five under yellow alert for rain-flooding for Wednesday, November 4. Torrential rain is subsequently reported in the South-East and Corsica, where scientists are questioning the predictability of such extreme events, while stormy rain affects the east and centre of the island.

## Background

_Context and reference points, separate from the story’s news; every item links to its source._

**Reference points**

- The October 2015 floods in the Alpes-Maritimes were caused by heavy rainfall during the night of October 3-4, 2015, with exceptional flooding affecting Cannes, Antibes, Vallauris, Biot and Mandelieu-la-Napoule. An analysis by the University of Nice concluded that the recurrence of such events was inevitable. ([Wikipédia](https://fr.wikipedia.org/wiki/Inondations_d%27octobre_2015_dans_les_Alpes-Maritimes))
- On October 29, 2026, an order published in the Official Journal recognized the state of natural disaster for 34 municipalities in Haute-Corse, a week after severe weather struck the Plaine orientale. ([Acturadar archives, 2026](https://acturadar.com/en/stories/154.md))

**Key terms**

- **Weather vigilance**: Météo-France's weather vigilance is a national procedure for informing the public, government authorities, civil security services and health authorities in the event of dangerous weather phenomena predicted by Météo-France. It draws everyone's attention to the potential dangers at the departmental level of a particular meteorological situation and informs about possible consequences and specific precautions to best protect oneself. ([Wikipédia](https://fr.wikipedia.org/wiki/Vigilance_m%C3%A9t%C3%A9orologique_de_M%C3%A9t%C3%A9o-France))
- **Mediterranean episode**: In meteorology, a Mediterranean episode is the simultaneous occurrence of intense thunderstorms and strong convective water sheets (heavy accumulations). Such episodes occur around the Mediterranean Sea and can cause local flash floods. ([Wikipédia](https://fr.wikipedia.org/wiki/%C3%89pisode_m%C3%A9diterran%C3%A9en))
- **Rain-flooding**: A flood is the temporary natural or artificial submersion of an area by liquid water. This term is frequently used to describe very significant runoff of pluvial origin, either on cultivated land (muddy flooding) or in impermeable urbanized areas. ([Wikipédia](https://fr.wikipedia.org/wiki/Inondation))

**What happens next?**

_What usually happens in this kind of situation, without prejudging the outcome._
