.SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...

Broad surface high remains close to the northern Gulf Coast,
maintaining a weak pressure gradient and generally benign marine
conditions. Weakening subsidence aloft has allowed for some
convection over the open Gulf waters this afternoon but coverage is
quite isolated. Winds will remain light and somewhat variable
nearshore, becoming more consistently onshore during the afternoon
with the sea breeze. Convective coverage will increase Monday as
deeper moisture returns and upper-level subsidence further weakens.
Any thunderstorm could briefly produce locally higher winds and
seas, frequent lightning, and reduced visibility, but widespread
marine hazards are not expected.

High pressure will remain close enough to the region through Tuesday
to maintain generally light winds. A more persistent northeast to
east flow should develop Wednesday through the latter part of the
week as surface high pressure builds southeastward across the
eastern United States. At this time, winds and seas are still
expected to remain below headline criteria.
