Tension eases somewhat in the Paris region. After a turbulent Thursday, Paris (75) and the entire Île-de-France area (Seine-et-Marne 77, Yvelines 78, Essonne 91, Hauts-de-Seine 92, Seine-Saint-Denis 93, Val-de-Marne 94 and Val-d'Oise 95) are now under a yellow thunderstorm alert this Friday, August 28, 2026, according to the latest forecasts from Météo-France. A level that urges caution, but without the ferocity seen the day before.
On the weather side, the morning remains gloomy over the region. In Paris, the thermometer shows around 17°C under a cloudy sky, with scattered showers and a humid spell. Temperatures struggle to rise and are expected to peak around 22°C this afternoon, with a low near 16°C. The risk of rain stays high for the entire day, with more than a fifty percent chance of a few showers, sometimes in the form of thunderstorms.
The fiercest part of the episode unfolded away from the capital. At 6 a.m. this Friday, Météo-France lifted the orange storm alert over the Vosges, Haute-Marne, Haute-Saône, Côte-d'Or, Saône-et-Loire, the Loire and Haute-Loire.
Several departments remain on alert. The Rhône, Ain, Jura, Doubs, Territoire de Belfort, Haut-Rhin and Bas-Rhin stay in orange alert, with monitoring even extended there beyond what was initially planned.
The official vigilance map from Météo-France Vigilance remains the go-to reference for real-time alert levels in your department. It is updated at least twice a day, at 6:00 AM and 4:00 PM.
The pattern is the same as usual for this late summer: cool, dynamic air aloft sits above warm, humid air in the lower layers, a contrast that fuels the development of orages sometimes violent storms. A very hot air mass also lingers over Corsica.
After a bout of strong thunderstorms Thursday afternoon and evening (hail, gusty winds, heavy rain), the storm cells eased off in the early hours of the night. Two areas remain notable: storms shifting up from the Vosges and Haute-Saône toward Alsace, and newly developing cells over the Massif Central marching toward the Rhône valley.
The most active weather axis is gradually shifting eastward. In the affected areas, storms may stay strong, bringing hail, powerful gusts (80 to 100 km/h, locally higher) and heavy rain in short bursts (up to 30 mm in an hour). Météo-France also warns of a possible uptick in the alert level: the storms could intensify Friday morning from Drôme and Ardèche toward Savoy. The alert level remains yellow, but you should monitor the situation.
Under a yellow alert, the risk remains present without being exceptional. It’s wiser to postpone outdoor activities until the sky stabilizes. Seek shelter in a sturdy building, stay away from trees and watercourses, and limit the use of electrical devices and mobile phones if a bolt strikes. Also secure any objects exposed to the wind on balconies and terraces.
Now is the perfect moment to lean toward indoor activities. The Parisian museums and the many current exhibitions provide a sheltered refuge to stay dry, just like the cinemas. It could turn a gray morning into a cultural pause. To plan your day, find all our ideas in our guide to the this Friday’s outings, August 28, 2026.
