Seas given as significant wave height, which is the average
height of the highest 1/3 of the waves. Individual waves may be

Synopsis for the Gulf of Mexico

.SYNOPSIS...A surface ridge will remain the dominant feature
across the basin through early this week, currently anchored by
a 1018 mb high centered near 28N89W. This will support gentle to
moderate winds, except over the eastern Bay of Campeche during
the middle to latter part of the week, where winds will be
enhanced by a thermal trough that will emerge off the Yucatan
Peninsula each night. High pressure will shift SE into the east
Gulf Tue and Wed and allow for moderate return flow to develop
across the W Gulf Wed through Fri.
