Expert opinion

Low 980 hPa centered on the East of the North Sea remaining almost stationary.

For Helius Harbour :
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 end.

Very cloudy skies to overcast. Showers. In the evening, good clear periods but lots of cloud, too.
No precipitation. WNW force 6 in the middle of the day becoming force 5 in the evening. Gusts reaching 41 knots in the middle of the day. Slight sea. Low, fairly long swell from E. Excellent visibility.
