Synopsis for the Gulf of America
1115 PM EDT Wed Sep 16 2026
.SYNOPSIS...The gradient related to high pressure over the
eastern U.S. that stretches a ridge SW to the SE U.S. is
sustaining fresh to strong NE to E 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 towards Florida
from the western Atlantic Thu through Fri as it transitions into
a low pressure. This feature will lead to increasing shower and
thunderstorm activity over the eastern and central Gulf waters.
