.SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...
A prolonged easterly wind of 15 to 25 knots will persist through
Sunday as the waters remained sandwiched between a broad low in. the
Gulf and a high pressure system to the north. The combination of
wind waves and swell from a long fetch across the eastern Gulf will
produce rough seas of 6 to 10 feet in the open Gulf waters and 3 to
6 feet in the sounds and tidal lakes. A Small Craft Advisory will
remain in effect for all of the open Gulf waters and the tidal
sounds, as well as Lake Borgne through Sunday evening due to these
expected rough conditions. Small Craft Exercise Caution headlines
will also be in effect Lakes Pontchartrain and Maurepas. Conditions
will gradually improve early next week as high pressure becomes more
centered over the area.
