Synopsis for the Gulf of Mexico

.SYNOPSIS...Strong winds and building seas follow a cold front
currently extending from southwest Louisiana to south of the
mouth of the Rio Grande. The front will reach from near Panama
City, Florida to Coatzacoalcos, Mexico by this evening. Winds to
gale force will follow the front over the far western Gulf off
the coast of Mexico. The front will slowly move across the Gulf
through late Sun, spreading strong to near- gale N to NE winds
and rough seas into the east-central and central Gulf. Frequent
gusts to gale-force are possible at the central Gulf late Sat
afternoon through Sun, and at the eastern Bay of Campeche Sun
night. As the front continues southeastward passing through the
Yucatan Channel and Florida Straits on Sun night, both winds and
seas should gradually subside across the Gulf on Mon.
