.SYNOPSIS...

High pressure building from the north will usher a brief surge of
northeast winds across the waters today and elevate seas; small
craft are urged to exercise caution. A weaker pressure pattern
will begin Sunday and continue through the middle of next week as
high pressure extends to the east. Late next week, an area of
disturbed weather in the western Caribbean may develop into a
broad tropical system as it tracks northward into the Gulf of
Mexico. Interests are urged to monitor the National Hurricane
Center for forecasts and updates with the potential tropical
disturbance next week.
