Bulletin météo du 4 janvier 2015

Cheminées Poujoulat navigue au reaching dans des vents modérés et progresse rapidement vers le nord vers la zone de convergence de l'Atlantique Sud. En traversant cette zone de convergence, ils devraient ensuite rejoindre les alizés de l'hémisphère sud qui les mèneront jusqu'au Pot au noir. Neutrogena et GAES Centros Auditivos naviguent vers le nord, mais doivent traverser une dorsale avec des vents légers.

Dans le Pacifique Sud, We Are Water, One Planet One Ocean & Pharmaton et Renault Captur sont dans des vents forts le long de la zone d'exclusion. Spirit of Hungary navigue dans des vents faibles autour d'une zone complexe de hautes pressions.
