Expert opinion

Low 976 hPa centered to the North-West of Ireland moving at 18 knots to the South and dropping to 962 hPa to be centered at 210 nautical miles in the West-South-West of Ouessant.

For Grèves d"en Bas :
Warning strong breeze offshore.

We are 80% sure of the situation, because the high pressure system could move in more quickly than forecast.
