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

Surface high pressure centered near and just southeast of the
Mississippi River mouth will maintain a generally west to northwest
wind at around 10 knots through the weekend. The northwest to north
flow will be strongest during the overnight hours approaching
15 knots before winds diminish during the day. Thunderstorm coverage
will remain very limited today but isolated storms may reach the
eastern waters tonight through Monday as the eastern-Gulf upper low
edges closer, but most of the marine area should remain dry. By mid
week, winds remain westerly at around 10 knots and rain chances will
also increase modestly in waters east of the Miss River as deeper
moisture returns, although widespread marine convection is not
presently expected.
