Yellow thunderstorm alert on Monday, October 20: Météo France has placed Paris and the entire Île-de-France region on thunderstorm alert for today. The eight departments of the Île-de-France region (Paris, Seine-et-Marne, Yvelines, Essonne, Hauts-de-Seine, Seine-Saint-Denis, Val-de-Marne, and Val-d'Oise) are among the 30 departments in France affected by this weather alert. This situation was unexpected, as the deterioration in weather conditions had been forecast since Sunday, October 19. Monday is expected to be gloomy in the capital and its surrounding region.
On Sunday evening, residents of the Paris region saw the return of rain, with showers accompanied by very cloudy skies. The rainfall continued throughout the night, with a total of around 3 mm expected, while temperatures remained relatively mild at around 15°C at the start of the night. This first wave of rain was just a prelude to a more turbulent Monday than expected.

Météo France is forecasting locally stormy showers with a total of around 4 mm of rain and temperatures rising slightly to 17°C.
