Low 988 hPa centered to the West of Ireland moving at 9 knots to the North-North-West and rising to 992 hPa to be centered at 90 nautical miles in the West-North-West of Belmullet (North-West Ireland).

For Grève de Fonteny :
Warning strong breeze offshore.

We are 85% sure of the situation, because in this type of situation, it is difficult to define precisely when the precipitation will end.

In the evening, good clear periods but cloud building.
Heavy showers. S wind force 5. Gusts reaching 26 knots in the evening. Smooth to slight sea. Low, fairly long swell from SSW. Excellent visibility.
