Marine Weather HF Voice Broadcast for the Gulf of Mexico

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 for the Gulf of Mexico

.SYNOPSIS...High pressure will dominate the basin through Fri
producing mainly gentle to moderate E to SE winds. Fresh winds
will pulse west of the Yucatan Peninsula tonight and again Wed
night. An area of low pressure is expected to form in the
western Caribbean late this week, and this system could approach
the Yucatan Peninsula or Belize by Sat. There is a medium chance
of tropical cyclone formation within the next 5 days. An
increasing pressure gradient between high pressure over the Gulf
waters and the possible tropical system over the western
Caribbean will result in fresh to strong easterly winds over the
SE and south-central Gulf during the upcoming weekend.
