Butlletí del 19/03/2015

Després de navegar al nord cap a una alta pressió a les Açores, el Cheminées Poujoulat ha virat cap a l'est per navegar amb el vent del nord que s'està formant entre l'alta i la baixa pressió que s'està desenvolupant a la costa oest del Brasil i el Golf de Cadis. Navegaran cap a l'est entre les aigües de Madeira i les Canàries buscant una brisa que els porti cap al nord, cap a Gibraltar. El Neutrogena i el GAES Centros Auditivos continuen navegant cap al nord amb condicions moderades amb els vents alisis. Tenen al davant molts dies abans d'haver de virar a l'est. El We Are Water i el One Planet, One Ocean & Pharmaton segueixen el seu camí cap al nord amb alisis de l'Atlàntic Sud. Estan passant ara per la zona de major vent, i el vent començarà a afluixar i virar a mesura que s'acostin als doldrums en les pròximes 24-48 hores. Al sud-est del Brasil, el Renault Captur progressa gradualment cap al nord-est amb vent suau i mar pla. L'Spirit of Hungary, per la seva banda, navega cap al sud-est amb bon vent del nord amb una alta pressió que queda ara a l'est de la seva posició.
