.SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...
Light south to southwest winds around 5 to 10 kt will continue
through tonight ahead of an approaching cold front. The main concern
tonight will be dense fog, especially across the Mississippi Sound,
Lake Borgne, and Chandeleur Sound, where visibilities could fall
below 1 NM. Dense Fog Advisories are in effect for portions of these
waters through Wednesday morning. A few showers and thunderstorms
will also be possible as the front moves through Wednesday, with
winds shifting to the northwest behind it. However, the pressure
gradient will remain rather weak, so winds should stay relatively
light through Thursday as surface high pressure moves across the
waters. Another weak front will move through Friday with some
scattered showers possible, mainly across the southern waters. A
stronger reinforcing front will follow Friday night into Saturday,
bringing increasing north to northeast winds around 10 to 15 kt,
with some winds approaching 20 kt across the outer waters Saturday
night. Another increase in northerly winds is expected Sunday into
Sunday night, potentially reaching Small Craft Advisory criteria as
seas build.
