Bulletin météo du 12 mars

Le leader Cheminées Poujoulat progresse dans des alizés de nord-est modérés. Ils devraient fraîchir, selon les prévisions, libérant les angles à mesure qu'il progresse vers le nord, sur la route la plus directe.

Comme prévu, Neutrogena et GAES Centros Auditivos allongent l'allure dans des alizés devenus plus consistants vers le nord. Avec un Pot au noir juste au sud de l'équateur, les équipages sont à quelques jours de passer dans l'hémisphère Nord.

We are Water et One Planet One Ocean naviguent toujours sur une route nord-est dans des vents de sud-ouest faiblissant. Ils devront traverser une zone de vents légers dans les prochains jours avant d'entamer la remontée vers le nord vers les alizés de nord au niveau de la latitude 30°S.

Après avoir affronter des conditions sévères au passage du cap Horn, Renault Captur se retrouve dans des vents bien plus légers, associés à un anticyclone au nord-ouest des Malouines. Il doit toucher des vents de nord - nord-est s'établissant progressivement dans la journée à mesure que l'anticyclone se déplacera rapidement à l'est des Malouines.

Spirit of Hungary avance toujours des vents de sud-ouest soutenus, dans des conditions ayant néanmoins faibli depuis hier.
