Floods, wind, thunderstorms… The Pyrénées-Atlantiques on orange alert, chaotic weather on the west coast

Floods in the 64

The organization has also placed the Pyrénées-Atlantiques in orange vigilance for the risk of rain-flooding because of an “episode of sustained and lasting rain”. 21 other departments, particularly in the South-West, are also on yellow alert for various phenomena. In New Aquitaine, caution for the risk of strong winds in Charente-Maritime, Gironde, Landes, Pyrénées-Atlantiques, Vendée and Deux-Sèvres. Two storm and wave-submersion vigilances concern Charente-Maritime, Gironde, Landes and Pyrénées-Atlantiques. In these last two departments, we must also add raw vigilance.

In the Pyrénées-Atlantiques, the TER Nouvelle-Aquitaine account reported flooding on the tracks which are disrupting regional train traffic. Thus, around 3 p.m., traffic was interrupted on the Bayonne – Saint-Jean-Pied-de-Port axis, with a return to normal traffic expected around 9 p.m.

On the Puyôo-Pau axis, the fall of a tree forced the line to be interrupted.

Up to 90 mm of rain in the Pyrénées-Atlantiques

Since Monday morning, sometimes intense rains have affected the Southwest. According to Météo-France, they should intensify further during the afternoon, taking on a stormy character in the Pyrénées-Atlantiques. After a very slight lull at the end of the day, the showers are gaining in intensity again at the start of the night from Monday to Tuesday. By Tuesday noon, it could fall between 60 and 80 mm of rain, or even locally 90 mm, Météo-France alert in its vigilance bulletin. The rain-snow limit should be around 1,200 meters in the Pyrenees.

In the afternoon, the westerly wind will strengthen on the Atlantic coast and the coasts of the Channel, reaching 90 km / h in gusts, even 100 to 110 km / h on the exposed capes. It will strengthen a little more in the evening with a risk of locally strong thunderstorms, accompanied by hail, according to Keraunos.

At sea, the maritime prefecture warns against winds of force 7 to 8 on the tip of La Hague, in the Channel, and the Atlantic coast. Météo-France also warns of a fairly strong swell expected during the night which could limit the flow of water towards the ocean near the Basque coast.

Caution also in Corsica, where a start of bad weather is expected at the end of the day, Keraunos alert. Occasionally heavy and stormy rains can produce layers of water greater than 70 mm in a short time.

And Tuesday?

The situation will not be much better on Tuesday with still very turbulent weather in the Southwest, predicts La Chaîne Météo. However, from the beginning of the afternoon of Tuesday, the showers will become increasingly rare in the Pyrénées-Atlantiques and gradually lose intensity.

Corsica should again be affected by locally violent storms. Gusts of up to 150 km / h should affect the island of Beauty.
