Synopsis for the Gulf of Mexico

.SYNOPSIS...Surface ridging will be the dominant feature across
the Gulf with a center of high pressure intermittently forming
and dissipating mainly in the north-central and northeast
regions of the basin. Otherwise, a surface trough will be
developing in the Yucatan Peninsula each evening before pushing
offshore into the SW Gulf each night. The trough will drift
westward during the overnight hours, and dissipate in the SW
Gulf each morning. Fresh to strong winds are possible in the SW
basin during the weekend and early next week at night associated
with the trough.
