Météo-France placed several western departments under yellow and orange storm vigilance early on Sunday 4 October, citing heavy rain and gusts that could top 90 km/h in exposed coastal areas. The bulletin, released at 06:00 Paris time, advises caution on the roads and warns of possible localised flooding. Paris Aéroports said overnight that it is monitoring conditions closely; while no flights have been cancelled, ground-handling operations at Orly and Charles-de-Gaulle could be slowed if lightning risks rise. Regional carriers operating into Nantes, Bordeaux and Biarritz have already activated weather waivers, allowing passengers to re-book within seven days without fee. Rail operator SNCF Voyageurs has instructed drivers on Atlantic and south-western lines to apply reduced speed protocols if wind thresholds are exceeded, which could lengthen journey times for TGV Atlantique and Intercités services. Road-haulage associations have asked companies moving time-sensitive cargo to reroute via eastern corridors where possible. Travellers scheduled to arrive in or depart from affected zones today should check airline, rail and traffic updates before setting off and allow additional connection time. Mobility managers may wish to alert assignees relocating this week that the delivery of household goods by road could be delayed by weather-related restrictions on high-sided vehicles.
