A southeasterly, moderate and very variable flow prevails over the North of the basin. Over the South, it is westerly, strong and very variable.

For Saint-Nazaire :
Warning strong breeze offshore.

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