Porto-Vecchio floods: affected roads and safety checks

The RT10 had reopened, but three sections remained closed in the 8 p.m. local Corsica update on November 4, 2026: the road from Precojo to Ceccia, the RD859 between Ceccia and Sotta, and the RD459 at Cardetto. Other parts of the RD859 were described as difficult to travel. Before leaving, check the forecast, available river information and current local road conditions again.

This is a dated snapshot, not a live traffic dashboard. Conditions can change, and the reopening of a main road does not confirm that its access roads or connecting secondary routes are safe.

Which roads were affected

According to the situation report published by Corse Net Infos, the RT10 had been closed but was listed as open again in the 8 p.m. local Corsica update. The Precojo–Ceccia road, the RD859 between Ceccia and Sotta, and the RD459 at Cardetto remained closed.

Other sections of the RD859 were still difficult to travel. Flooding points, landslides and traffic jams had also been reported across the road network around Porto-Vecchio, Sotta and Figari. The advice relayed at the time was to limit travel and avoid the south of the Porto-Vecchio municipality as well as Sotta and Figari.

The distinction matters: reopening the RT10 did not mean that traffic throughout the area had returned to normal. A journey using that main road could still depend on a closed or damaged secondary route.

The emergency update

Heavy rainfall affected Porto-Vecchio, Sotta and Figari. In the 8 p.m. local Corsica update reproduced by the local outlet, 40 firefighters and 13 vehicles had been deployed for ten interventions that were completed or still under way.

Twenty people had been moved to safety. Three were removed from vehicles, while another person was rescued as their car was being swept away by water. Ten flooded homes had been recorded at that point.

Although the intensity of the rain was beginning to decrease, flooded roads and landslides remained. A pause or reduction in rainfall was therefore not enough to conclude that a road was safe.

The forecast maintained the risk

The Porto-Vecchio bulletin issued at 3 p.m., local time in mainland France and Corsica, on November 4 forecast rain or showers overnight, with 15 millimetres. It indicated another 15 millimetres on the morning of November 5 and 25 millimetres in the afternoon.

The Météo-France forecast for Porto-Vecchio placed Corsica under orange rain and flood vigilance for November 5. It also forecast fairly strong easterly wind in the morning and local gusts of up to 55 km/h late in the afternoon.

Those figures belong to the cited forecast and are not permanent or live observations. Before driving, reopen the official page and check the current forecast and vigilance status.

Météo-France and Vigicrues serve different purposes

Météo-France provides forecast developments, expected rainfall and meteorological vigilance. Vigicrues for the Corsican basin monitors river sections and stations. Porto-Vecchio at Pont de Bala was included among the listed stations.

The Vigicrues territorial bulletin had been published at 3:55 p.m., metropolitan legal time, on November 4. The page said that information was produced at least twice daily. It also showed that some stations might have no water-level or flow data available.

No river level, vigilance colour or isolated reading authorizes passage along a road. A measurement from one watercourse also does not automatically represent surface-water flooding, landslides or damage elsewhere on the road network.

What to check before departure

Use Météo-France to check rainfall and vigilance, and Vigicrues to review the available hydrological picture. For traffic conditions, check Inforoute Corse when departing and comply with closures and instructions found locally. This article does not use a current snapshot of that portal to declare any road reopened.

Establish whether the journey depends on Precojo–Ceccia, the RD859 or the RD459 at Cardetto. Even though the RT10 was reopened in the evening update, do not assume that every connecting road is passable.

If there is a barrier, closure or water over the road, do not continue because the incident is absent from another service. The episode had already required vehicle rescues, including one involving a car being swept away.

What can be stated reliably

At 8 p.m. local Corsica time on November 4, the local report described the RT10 as reopened. Precojo–Ceccia, the RD859 between Ceccia and Sotta, and the RD459 at Cardetto remained closed; other RD859 sections were difficult. The forecast indicated further rain and orange vigilance in Corsica the following day.

Beyond that dated snapshot, each road’s condition must be checked again. Weather forecasting, river monitoring and road information answer different questions; none of them alone overrides a physical closure or instructions issued by authorities along the route.
