Expert opinion

A northwesterly, very strong and variable flow prevails over the whole area.

For Saint-Nazaire :
Warning fresh gale offshore.

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

Very cloudy. But clear spells will become more and more widespread. Rain gradually becoming less frequent in the morning, no precipitation in the afternoon. In the evening, good clear periods but lots of cloud, too.
No precipitation. WNW force 5 in the morning becoming force 4 in the evening. Gusts reaching 35 knots in the morning. Slight sea. Low, fairly long swell from WSW. Good visibility becoming excellent in the middle of the day.
