Predictwind indicates that winds will be just under the limit for racing in the second and third round of the Finals for the Louis Vuitton Cup between Italian Challenger Luna Rossa, and Emirates Team New Zealand when they meet on Sunday August 18, 2013 in San Francisco.

The first 25 minute race is due to start at 1310hrs local time, with the second about an hour later.

The top image shows the wind speed and direction at 1315hrs with it building to around 18ts - these are only average speeds and gusts will be higher. The breze should be under the limit for the fits race of the day but will build to over 20kts by 2.00pm - the time for the second race start, however not to the levels seen yesterday. The wind limit is believed to be 19-20kts.


The second image shows a graphic representation of the wind build - confirming the numbers for the prognosis.


The next two images are showing the same style of information except for an hour later around the time of the second race for the day. in the intervening time winds will increase a little but should not delay racing - however conditions will be marginal for racing in terms of the wind limit.

Two weather feeds are used by Predictwind, the key to the accuracy of the forecast lies with the graphs, as when the two lines for the two feeds are quite close together and following each other in the trend, then the likelihood of the forecast is high. If there is separation to any marked degree, then there still some issues to be resolved but usually 24 hours from the race they are well aligned.



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 the image with the funneling of the breeze.
