Synopsis for the Gulf of America

1022 PM EDT Tue Oct 20 2026



.SYNOPSIS...High pressure over the eastern U.S. will support 

fresh to NE winds across the basin through the week, except 

for strong NW to N winds over the SW Gulf through Wed. 

The high combined with low pressure that is expected

to develop near the Bahamas, will support strong to near-gale NE 

winds and rough seas over the eastern Gulf Sat. These conditions 

will spread westward to the central Gulf Sat night through Sun 

night. Seas are expected to peak to 12 ft with these winds.
