Expert opinion

A westerly, strong and mostly variable flow prevails over the whole area.

For Carnac :
Warning strong breeze offshore.

We are 80% sure of the situation, because in this type of situation, it is difficult to define precisely when the precipitation will end.

Very cloudy with risk of thunderstorms in the morning, cloudy spells, sometimes dense, in the afternoon. Some light showers in the morning, possibility of a few spots in the afternoon. In the evening, good clear periods but cloud building.
No precipitation. WNW wind force 5 continuing all day. Gusts reaching 31 knots in the middle of the day. Slight sea. Low, fairly long swell from SSW. Excellent visibility.
