SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM

As we continue into the week, a strong dome of high pressure dominates the region leading to mostly easterly winds at 5-10 kt. There is also a signal for fog through the week and there will likely be additional marine dense fog advisories, especially right along the coast. The next front is due into the region early next week. Look for winds to be on the increase very late in the period with this feature.
