Expert opinion

For Crique du Grand Mathieu :
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 with reduced visibility in the morning, very cloudy skies becoming totally covered in the afternoon. Light showers progressively dying out in the morning, possibility of a few spots in the afternoon. In the evening, very cloudy.
No precipitation. SSE force 3 in the morning turning SSW in the evening. Gusts reaching 14 knots in the evening. Slight sea. Low, fairly long swell from WSW. Visibility reduced by mist becoming poor in the middle of the day then good.
