For Lostmarc"h :
Warning moderate gale offshore.

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

Overcast skies. Risk of some spots of rain in the morning, showers in the afternoon. In the evening, overcast skies.
Heavy showers. S force 5 becoming force 6 in the middle of the day then WNW force 3. Gusts reaching 34 knots in the middle of the day. Moderate sea temporarily rough in the middle of the day. Moderate, fairly long swell from W. Excellent visibility becoming good in the evening.
