Expert opinion

Low 1008 hPa centered on the North of the Bay of Biscay moving at 10 knots to the West to be centered at 170 nautical miles in the West of the Île de Sein.

For Plage du Marchais :
No gale warning.

We are 85% sure of the situation, because in this type of situation, it is difficult to define precisely when the precipitation will end.

Overcast skies with storms likely in the morning, good clear periods with lots of cloud in the afternoon. Some showers in the morning, possibility of a few spots in the afternoon. In the evening, skies with few clouds.
SSE force 4 becoming SE force 3 in the middle of the day then NW force 2. Gusts reaching 17 knots in the morning. Smooth to slight sea. Low, short swell from WNW. Poor visibility becoming excellent in the middle of the day then good.
