Synopsis for the Gulf of America
418 PM EDT Wed Sep 16 2026
.SYNOPSIS...The gradient related to high pressure ridging over
the eastern U.S. that stretches southwestward to the
southeastern U.S. is sustaining fresh to strong northeast to east
winds and moderate to rough seas over the NE Gulf. These
conditions will spread westward over the remainder of the
northern Gulf waters through late Thu night before improving
Fri into Sat, leading to moderate or weaker winds and slight to
moderate seas during the weekend. Meanwhile, a rather broad mid to
upper-level trough will move toward Florida from the western
Atlantic Thu through Fri as it transitions to low pressure. This
feature will lead to increasing shower and thunderstorm activity
over the eastern and central Gulf waters.
