Weather forecast 11 FEB 2015

The leaders are moving quickly now in relentless winds across the Tasman Sea. They are being chased by a strong cold front which will move east across the Tasman Sea with storm force winds possible tomorrow. The remainder of the fleet continues to manage their courses along the edge of the ice exclusion boundary, where the stronger, more consistent breezes are found. High pressure to the north means that few options exist.
