Météo-France kept a yellow storm warning for rain and flooding for Île-de-France on Sunday, 25 October 2026, and added strong winds to the alert. Paris and the eight listed departments are in the zone, with rain already expected from the second part of Saturday.
The warning matters because the rain is expected to meet very dry soils in Île-de-France after the historic drought of 2026. That makes runoff more likely to collect in cellars, basements, low road sections and underpasses, while the article says this is not a flood of the Senei.
Paris and eight departments
The alert covers Paris, Seine-et-Marne, Yvelines, Essonne, Hauts-de-Seine, Seine-Saint-Denis, Val-de-Marne and Val-d'Oise. Météo-France also says the wind should ease during the day, with the afternoon turning much brighter and a maximum of about 15°C in Paris.
For residents of Paris and the surrounding departments, the practical issue is not a river overflow but surface water moving faster than drains can take it. Vigicrues remains the reference source for monitoring watercourse levels, which keeps the focus on local flooding points rather than on a wider river crisis.
Boelo over Scotland
The system driving the weather is Boelo, named by the Met Office in the United Kingdom and deepening far to the north near Scotland. France is spared the strongest winds from Boelo, yet Météo-France still adds a strong-wind warning for Île-de-France because the depression is pushing a rainy front and a sustained west wind toward the country.
Météo Paris estimated 10 to 15 mm of rain in Paris by the end of the day, while Météo-France forecast rather 6 mm. The same split appears on wind: Météo-France expects gusts of nearly 65 km/h in Paris on Sunday morning, while Météo Paris estimated up to 70 km/h.
Winter time and Sunday morning
The timing adds a complication for residents moving around overnight. The switch to winter time takes place in the night from Saturday to Sunday, so when it reaches 3 a.m., it becomes 2 a.m.
Météo-France recommends bringing in or securing objects on balconies and terraces, avoiding parking under trees, and staying away from parks and forests during gusts. It also says drivers should slow down and never enter a flooded road, even if the water seems shallow, as the strongest effects should come during Sunday morning before conditions ease later in the day.
