.SYNOPSIS...The Atlantic ridge extending into the NE Caribbean

will shift eastward this weekend allowing a frontal boundary to 

reach the island by Sun morning. Under this weather pattern, the

southerly winds will veer to the N and NE on Sun, and to the NE 

starting on Sun night as high pressure builds over the western 

Atlantic in the wake of the front. Moderate to locally fresh

winds and moderate seas will prevail through the forecast

period. Periods of unsettled weather are also expected this 

weekend with the proximity of the front.
