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

No real relief for fog over coastal areas again tonight/Fri morning
with the fog remaining in some areas through much of the day and
widespread overnight into the end of the week which will likely
bring additional marine dense fog advisories, especially right along
the coast. This fog may not lift in many areas near the coast, but
as land heating gets going, we should see some erosion over water
bodies that can move this air over the water. A cold front is due
into the northern gulf starting around noon Monday. This will
definitely move the fog issue away. Look for winds to rapidly
increase from the north as the front moves through Monday and start
easing late Tue into Wed. Strongest wind speeds should be Monday
night as sustained could reach 25 to 30kt with gusts to gale force.
