Synopsis for the Gulf of America

303 PM EDT Sat Sep 12 2026



.SYNOPSIS...Weak high pressure will bring relatively tranquil

conditions to Gulf waters into the start of next week. The

exception will be the Bay of Campeche, where a diurnal trough will

move westward offshore the Yucatan Peninsula each evening,

bringing nightly pulses of fresh NE winds. Starting later Tue,

stronger high pressure building southward from the eastern United

States will lead to increasing NE to E winds over the basin, with

speeds reaching fresh to strong over the NE basin Wed and Thu.
