We are 85% sure of the situation, because it is possible that the change in the rain system may not be as clear as forecast.

Overcast skies. Some light showers in the morning, light rain followed by showers in the afternoon. In the evening, clear periods developing.
Light showers progressively becoming less frequent. S force 5 becoming force 6 in the middle of the day then WSW force 5. Gusts reaching 37 knots in the middle of the day. Moderate sea. Low, fairly long swell from WSW then moderate from SSW in the evening. Excellent visibility.
