.SYNOPSIS...Weak high pressure north of the front will support
relatively benign marine conditions through this evening. The

through the Yucatan Channel into the northwest Caribbean Sun
afternoon. Deep low pressure north of the area will support
strong W to NW winds and rough to very rough seas following the
front over the northwest Caribbean starting Sun night. Winds are
forecast to reach gale force over the Yucatan Channel and the
far northwest Caribbean by late Mon afternoon with seas building
as high as 18 ft. Strong winds and rough seas will follow the
