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

High pressure well to our northeast and a deepening surface low
along the lee side of the Rockies is helping build winds across the
local waters. A surface low will develop today and deepen as it
moves across the Plains and into the upper Mississippi Valley on
Sunday. Additionally, the high over the western portions of the
Atlantic will slide south and become centered east of the Carolinas.
This should maintain or even strengthen the gradient across the area
leading to additional strong southerly winds. This will keep Small
Craft Advisory conditions in place through Sunday night. Also, the
persistent southerly flow will produce a large fetch across the Gulf
with seas likely higher than typical as long swell develops.
