The Storm Nils is set to hit France on Wednesday, February 11, 2026, and Île-de-France is no exception. Météo-France has issued a yellow warning for the Paris region and its eight departments, starting at 10 p.m. Wednesday evening and lasting until around 4 p.m. on Thursday, February 12. In practice, public transportation users, especially those relying on the Transilien, should prepare for disturbances on certain lines overnight and during the Thursday morning rush.
During the night from Wednesday to Thursday, winds are expected to reach up to 80 km/h in the Yvelines, and possibly 85 km/h in the northwest of Val-d'Oise. Gusts of around 70 km/h could still be felt across Île-de-France Thursday morning. These wind speeds, combined with over-saturated soils from recent weeks, significantly heighten the risk of trees being uprooted — and potentially falling onto railway tracks.
The Transilien quickly issued a response. On their official blog, the N and U lines issued a warning: the upcoming Nils storm could disrupt train services starting from 10 p.m. this Wednesday evening and throughout Thursday, February 12, 2026. A similar message was echoed by the P line, which also alerted its passengers about potential disturbances.
These rail lines pass through extensive wooded areas in the outer suburbs—Yvelines for lines N and U, and Seine-et-Marne for line P—making them particularly susceptible to fallen trees on the tracks. This isn't the first occurrence this season: during the Goretti storm in January 2026, fierce winds reaching 90 to 120 km/h across Île-de-France caused service disruptions as early as 10 p.m. on the Dreux–Plaisir-Grignon line, with operations only resuming the next morning at 6 a.m.
Beyond the Transilien network, the RER lines operating in uncovered zones and the trams running on the surface are also likely to be affected by these windy conditions. Additionally, this network has already been weakened this week due to modernization work: notably, the RER D line has been interrupted during midday between Corbeil-Essonnes and Malesherbes, and new repair works have begun on the T4 and T11 tram lines.
Before heading out this Thursday, your first move should be to check the Île-de-France Mobilités app, which provides real-time traffic updates across all lines in the Île-de-France network. You can also follow the X account @lignesNetU_SNCF for updates on lines N and U, or verify your schedules on SNCF Connect and Transilien.com. With the yellow alert expected to last until around 4 p.m. Thursday, conditions are likely to gradually improve in the afternoon. The weather vigilance map remains available at any time on Météo-France’s website.
