Weather Risk Briefing

Low 1008 hPa centered on the South-East of the Bay of Biscay moving at 25 knots to the West and dropping to 1005 hPa to be centered at 310 nautical miles in the West-South-West of Fastnet Rock (South-West Ireland).

For Portsall :
No gale warning.

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

Good clear periods but with plenty of cloud in the morning, sunny becoming changeable in the afternoon. Risk of some spots of rain in the morning, no precipitation in the afternoon. In the evening, good clear periods but cloud building.
No precipitation. SSW force 1 in the morning freshening force 3 in the middle of the day. Gusts reaching 16 knots in the middle of the day. Slight sea. Low, fairly long swell from NNE then short from NNW in the middle of the day then from NNW. Good visibility becoming excellent in the middle of the day then poor.
