Synopsis for the Gulf of America
418 PM EDT Sat Jun 13 2026
.SYNOPSIS...A broad area of low pressure just offshore of eastern
Mexico is producing disorganized shower and thunderstorm activity.
Significant development is not anticipated before the low moves
inland over eastern Mexico by early Sunday. The system could re-
emerge over the northwestern Gulf of America on Tuesday or Wednesday
while interacting with a frontal boundary, but conditions there
are expected to be only marginally conducive for development.
The pressure gradient between the low pressure area and a ridge
over the NE Gulf will support fresh to strong SE winds and moderate
to rough seas, accompanied by scattered showers and thunderstorms,
through Sun night. The Atlantic ridge will build westward into
the Gulf Tue through Thu, and in combination with lower pressure
over South Texas and northeastern Mexico will promote fresh to
strong southerly winds over the western Gulf, and moderate to fresh
winds over the eastern Gulf.
