Weather Forecast 02/03/2015

Cheminees Poujoulat is using the last winds around a South Atlantic low to keep making easting before turning north. Their goal is to hopefully get around a high pressure off the South American coast as much as possible. Neutrogena and GAES Centros Auditivos are also sailing on more easterly courses as light and more variable conditions to the north fail to offer any viable routes.

For the rest of the race fleet typically strong and rough Southern Ocean conditions prevail as they work to optimize eastward progress along the edge of the Ice Exclusion Boundary.
