Synopsis for the Gulf of Mexico

.SYNOPSIS...A strong cold front extends from southwestern
Louisiana to inland Texas near Brownsville. The front will reach
the southeastern Gulf waters Wed and the Straits of Florida by
Wed evening. In the wake of the front, strong northerly winds
are expected in the western half of the basin, with gale force
winds expected west of 95W on Tue. A secondary front will drop
southward to the northern Gulf early on Fri and reach the far
southwestern Gulf by Fri evening. Strong high pressure will
build in behind this front. The pressure gradient between the
front and broad low pressure that is expected to form over the
western Caribbean by the end of the week is expected to freshen
the northeast winds over most of the southeastern Gulf by the
end of the week. These winds may reach strong speeds on Sat and
Sat night along with building seas.
