Synopsis for the Gulf of America
1025 AM EDT Sat Oct 18 2025

.SYNOPSIS...Moderate S to SE winds and slight to moderate seas
will prevail over the Gulf of America today. Locally fresh S to SE
winds are expected to develop tonight east of 90W, including
through the Florida Straits, as high pressure builds over the
western Atlantic. A cold front will move into the northwestern
Gulf Sun morning and move southeastward over the basin through
Mon. Moderate N to NE winds are expected north of the cold front,
and locally fresh winds will be possible north of 27N into Mon
morning. High pressure is slated to develop over the basin in the
wake of the front, leading to gentle to moderate winds and slight
seas over the Gulf early next week.
