Is snow expected in Paris this Wednesday, February 18, 2026? Snow and ice warning issued across Île-de-France

Several departments in northern and eastern France are under a yellow alert for snow and ice on Wednesday, February 18, 2026. In Île-de-France, the Val-d’Oise and Seine-et-Marne are affected. Here’s a roundup of the current situation.

Snow is making a return this Wednesday, February 18, 2026, covering a large northern and eastern swath of France. While Paris itself is not directly on alert, two departments in Ile-de-France—the Val-d'Oise (95) and Seine-et-Marne (77)—are under a yellow alert for snow and ice from Météo France. This alert also affects 17 other departments stretching from Seine-Maritime through the Vosges, including Oise, Somme, Ardennes, and Pas-de-Calais.

This latest episode isn't really unexpected. As early as last Sunday, meteorologists predicted that a low-pressure system would settle over France between Wednesday evening and Thursday, veered southward by the persistent cold air in the north. The forecast includes snowfall that could turn into snow in some regions. The scenario is indeed coming into focus, although the intensity remains moderate for now, with a yellow alert rather than the orange warning issued last Sunday.

Which departments in Île-de-France are affected by snowfall?

Currently, only Val-d'Oise and Seine-et-Marne are listed on Météo France's alert map. These two northern and eastern border departments are most exposed to cold air flows coming from the northeast. Temperatures across Île-de-France are expected to stay around 3°C to 4°C on Wednesday, according to Franceinfo Météo, making snow accumulation on the ground still quite possible in these areas. Paris and the other departments in the Île-de-France region are not currently under vigilance, but caution is advised, especially in the evening and overnight hours from Wednesday into Thursday.

Should we brace for a disruption as intense as last Sunday's episode?

Recalling that Ile-de-France was placed on orange alert for snow and ice on Sunday, February 15, with eight departments in the region affected and snowfall of 1 to 5 centimeters expected in some areas. A blanket of white had indeed covered Paris and the surrounding departments, causing disruptions to transportation and road traffic. Public transit faced significant disturbances, and airlines were forced to cut back flights by 30% at Roissy and 20% at Orly. This Wednesday, the alert level has eased but conditions remain conducive to slippery roads and black ice, especially later in the day and overnight. Everyone is advised to exercise caution.

What precautions should you take when dealing with snow in Île-de-France?

We recommend keeping a close eye on the Météo France updates, as the situation can change rapidly. If you're traveling through Val-d'Oise or Seine-et-Marne tonight, exercise extra caution on the roads and consider adjusting your speed accordingly. For public transportation, check the Ile-de-France Mobilités website for real-time traffic updates. This weather event also echoes the situation from January 7th, when RATP bus services were completely halted and speed restrictions to 70 km/h were implemented across the region.

In short, winter is still making its presence felt across Île-de-France this February 2026. Nothing to worry about for now, with the mild yellow alert, but it's best to stay alert to any changes. Keep your scarf and sturdy shoes close — you never know what might come next.
