Weather forecast 17/03/2015

Building high pressure near the Azores has brought stronger N/NNE winds to Cheminees Poujoulat. They will be continuing north toward the center of the high to get some leverage before tacking east toward the Gulf of Cadiz. Neutrogena and GAES Centros Auditivos are clear of the Doldrums and sailing north-northwest in building NNE/NE trade winds. Winds will increase and veer slightly with distance north. We Are Water and One Planet are hedging back toward the west again. They have cleared and area of lighter winds to their west, and should be seeing some fickle E ly trade winds developing. The trades will improve as they get further north. Renault Captur continues on a route further west than that take by the preceding boats. While more direct, the weather and winds patterns are quite unstable for them over the next few days. Spirit of Hungary has finally entered the Atlantic Ocean.
