Expert opinion

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

For Lagune du Letty :
Warning moderate gale offshore.

We are 85% sure of the situation, because the atmosphere might be less unstable and showers more frequent than forecast.

Dense and persistent fog in the morning, very cloudy skies becoming totally covered in the afternoon. No precipitation in the morning, possibility of showers in the afternoon. In the evening, very cloudy.
Chance of light rain. SSE force 2 turning SSW force 3 in the middle of the day then WSW. Gusts reaching 20 knots in the evening. Slight sea becoming smooth to slight in the evening. Low, fairly long swell from SSW. Visibility reduced by dense fog becoming poor in the middle of the day then excellent.
