.SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...
A tightening pressure gradient over the coastal waters will form in
response to a developing low pressure system in the southwestern
Gulf over the next few days. Winds will turn northeasterly behind
the front and increase back to 15 to 20 knots as drier air advects
over the warm waters with Exercise Caution headlines or Small Craft
Advisories likely to be necessary on Tuesday. Seas will also
increase to 5 to 7 feet by Wednesday. Depending on how the southwest
Gulf disturbance develops, there's potential for conditions to
deteriorate considerably beyond Wednesday, especially over the open
waters.
