Expert opinion

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

For Merlin :
No gale warning.

We are 90% sure of the situation, because in this type of situation, it is difficult to define precisely when the precipitation will end.

Skies very cloudy to overcast in the morning, cloudy spells, sometimes dense, in the afternoon. Some light showers in the morning, no precipitation in the afternoon. In the evening, very cloudy skies becoming totally overcast.
Showers towards the end of the night. ESE force 3 in the morning temporarily SSE force 4 in the middle of the day. Gusts reaching 18 knots in the middle of the day. Smooth to slight sea. Low, fairly long swell from SW. Poor visibility becoming excellent in the middle of the day.
