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...Relatively weak high pressure will prevail across
the basin through Wed night maintaining gentle to moderate winds
along with slight to moderate seas. Fresh northeast to east
winds will pulse along the Yucatan Peninsula each afternoon and
evening for the next few days as a trough develops inland daily
and shifts westward over the Bay of Campeche at night. Looking
ahead, winds may increase to fresh speeds across the NE Gulf on
Thu and Thu night and across the north-central part of the basin
on Fri as a broad and weak area of low pressure moves in a
general westward motion across the northern Gulf. This system
will bring increasing shower and thunderstorm activity over most
of the eastern and north-central Gulf waters starting today.
