Low 993 hPa centered to the South-West of Ireland moving at 8 knots to the East-South-East and rising to 1001 hPa to be centered on the Celtic Sea.

For Saint-Nazaire :
No gale warning.

We are 90% sure of the situation, because the atmosphere might be less unstable and showers more frequent than forecast.

Good clear periods but with plenty of cloud in the morning, very cloudy skies to overcast in the afternoon. Some light showers in the morning, possibility of showers in late afternoon. In the evening, overcast skies.
Showers. S wind force 3 continuing all day. Gusts reaching 19 knots in the middle of the day. Slight sea. Low, fairly long swell from WSW. Poor visibility becoming excellent in the middle of the day then poor.
