Expert opinion

High 1020 hPa centered on Switzerland remaining almost stationary.

For Plage du Bois de Cise :
Warning strong breeze offshore.

We are 80% sure of the situation, because in this type of situation, it is difficult to define precisely when the precipitation will end.

Very cloudy with risk of storms. Light showers progressively becoming less frequent. In the evening, good clear periods but cloud building.
Possibility of showers SW wind force 6 from the middle of the day. Gusts reaching 34 knots. Moderate sea. Low, short swell from WNW. Excellent visibility.
