The current trade winds expected to begin to weaken early next 
week, Monday, in response to the amplifying upper trof well to 
the northeast of the island along 150 to 155W. These weaker than 
average trades will then persist through the remainder of the 
week. PW values expected to be near seasonal averages through
mid-week, Wednesday. After this, PW may increase for the later
part of the week, although the GFS and EC are differing on how
much increase occurs, with the GFS more emphatic than the EC.
Through the upcoming forecast period, climatological precip 
distribution expected.
