The southerly wind strengthens during the night and still blows in the morning, particularly in the Basque Country, still with values close to, or even higher than, 80 km/h. The Pyrénées-Atlantiques are no longer on wind alert this Sunday morning (they remain on storm alert).

Gusts are noticeable across the entire Atlantic coast, of the order of 60 to 70 km/h, and also on the Breton peaks.

In the Autan area, gusts also reach 60 to 80 km/h, before weakening in the afternoon. On the other hand, the south wind picks up from Lyonnais to Val de Saône around 60 km/h.

A risk of waves-submersion in Brittany

At the same time, the depression over the British Isles caused a fairly strong swell which affected the coast of Finistère and Morbihan throughout the day.

But during high tide in the afternoon, a risk of submersion waves cannot be ruled out, warns the weather organization, which triggered yellow vigilance for these two departments on Sunday.
