Expert opinion

Low 990 hPa centered at 190 nautical miles in the South-South-West of Fastnet Rock (South-West Ireland) moving at 30 knots to the East-North-East and dropping to 976 hPa to be centered on the South-West of England.

For Grande Plage :
Warning fresh gale offshore.

We are 85% sure of the situation, because the atmosphere might be less unstable and showers rarer than forecast.

Cloud and sun in the morning, very cloudy skies becoming totally covered in the afternoon. No precipitation in the morning, light showers in the afternoon. In the evening, very cloudy with risk of storms.
Showers with the possibility of hail. SW force 2 turning S force 3 in the middle of the day then becoming force 5. Gusts reaching 35 knots in the evening. Smooth to slight sea. Low, short swell from NW. Poor visibility becoming excellent in the middle of the day.
