We are 85% sure of the situation, because the situation does not enable us to assess precisely how much the storm system will worsen.

Cloudy spells, dense at times in the morning, very cloudy with possibility of thunder storms in the afternoon. Risk of some spots of rain in the morning, light showers in the afternoon. In the evening, very cloudy skies becoming totally overcast.
Showers towards the end of the night. WSW force 5 becoming force 6 in the middle of the day then SW. Gusts reaching 30 knots in the evening. Moderate sea. Low, fairly long swell from WNW then moderate in the evening. Excellent visibility.
