Synopsis for the Gulf of Mexico

.SYNOPSIS...A cold front from the Straits of Florida to the
central Gulf will weaken as it moves southward today. High
pressure will build behind the front over the northeast Gulf
through early next week, supporting increased E to SE winds and
building seas over the western Gulf. Looking ahead, a weak cold
front will approach the Texas coast by mid week, then move into
the northwest Gulf by Thu night.
