We also have the first of what we hope will be a regular weather update from www.predictwind.com on conditions for tomorrow's race. A more detailed map will be published when we get inside the 12hour weather window.
The wind limit is 20kts before the start for the Round Robin phase of the Louis Vuitton Cup. the Predictwind model shows only predicted average winds, and not gusts which are, of course several knots above this average strength.
The other feature of the image above is that it quite clearly shows how lighter winds on the coast and surround ocean can be sucked in through the Golden Gate and the windspeed accelerates. The line of four yellow arrows show a wind of 15-20kts being build out of a sea breeze of 10-15kts further offshore.
The Predictwind model takes various weather feeds and then polishes these, part of this process is factoring in the effect of local topography on the breeze - well demonstrated by this image
