Expert commentary Weather outlook for the start

The strong trade winds seen in Antigua for the past two weeks collapsed three or four days ago as a cold front moved in from the north of the islands. Light rain early this morning heralded the passing of the front and the low-pressure system far to the north squeezed the dominant high-pressure region, which lately degraded, slightly south of the area.

The only trade wind cumuli were noted over the far eastern Atlantic waters and the ne to e trades are expected to increase early next week as the high pressure begins to strengthen further to the north.

If the trend follows the predictions on Monday ne winds develop and build from 15kts to 20 kts by mid morning. By Tuesday gradient winds of 19-20 kts are expected accompanied by a swell of some 3-4 metres is expected - the wave pattern will build in a NW direction due to the deep low in the far north

The dilemma for the RORC 600 Caribbean fleet will be how soon this pattern will develop and how good the prediction is regarding wind strength. Meteorologists in Guadeloupe and Martinique today were indicating a much lighter pattern than many of the grib sites (e.g. windguru) any of the fleet arriving at the entrance of the Anguilla channel by Monday night may find a tricky beat in light airs. Much will depend on the low to the north moving away quickly allowing the high pressure to re-establish
