Marine Weather HF Voice Broadcast for the Gulf of America



Seas given as significant wave height, which is the average

height of the highest 1/3 of the waves. Individual waves may be

more than twice the significant wave height.



.SYNOPSIS...A cold front extends from near Mobile Bay, Alabama

to just east Coatzacoalcos, Mexico this evening, and is followed

by strong to near-gale force N winds and building seas.

Gale-force winds will prevail off of Veracruz through midday Mon

before diminishing. The front will move slowly eastward,

reaching from the western Florida Panhandle to the eastern Bay

of Campeche Mon morning, from near Marco Island, Florida to the

northeast Yucatan Peninsula Tue morning, then exit to the

southeast of the basin by Tue evening. Strong northerly winds

and rough seas will follow the front across most of the Gulf

through Mon evening, before winds and seas diminish from west to

east through Tue night. Behind the front, high pressure will

settle across the northern Gulf Tue night through Thu to produce

gentle breezes and slight seas in all but the southeast Gulf,

where moderate NW swell will persist into early Wed.
