Expert opinion

Low 985 hPa centered at 70 nautical miles in the South-South-West of Fastnet Rock (South-West Ireland) moving at 32 knots to the East and dropping to 968 hPa to be centered on the South of England.

For Tharon :
Warning strong gale offshore.

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

Very cloudy skies with short clear spells. Risk of showers in the morning, no precipitation in the afternoon. In the evening, good clear periods but lots of cloud, too.
No precipitation. WNW force 7 becoming force 6 in the middle of the day then force 5. Gusts reaching 45 knots in the morning. Slight sea. Low, long swell from SSW. Excellent visibility.
