Expert opinion

A southeasterly, strong and mostly variable flow prevails over the North-East of the basin. Over the South and the West, it is westerly, very strong and mostly variable.

For Lost Marc"h :
Warning moderate gale 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.

Skies very cloudy, risk of thundery outbreaks in the morning. Some light showers in the morning, possibility of showers in the afternoon. In the evening, changeable skies with risk of storms.
Risk of showers in the early hours. WSW force 5 in the morning becoming W force 6 in the middle of the day. Gusts reaching 32 knots in the evening. Rough sea temporarily moderate in the middle of the day. Low, fairly long swell from SW. Excellent visibility.
