GMZ500-GMZ501-052300- 536 AM CDT Wed Aug 5 2026 .SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM... Surface high-pressure axis over the southern Gulf will become absorbed by the Bermuda ridge as the week progresses. This will alter flow to more of a south to southeast direction Thursday through the weekend. Speeds should generally remain around 5 to 10 knots, although periods of 10 to 15 knots will be possible over the outer waters as the easterly fetch becomes better established late in the week. Seas will generally remain 1 to 2 feet through Thursday. The low-level pressure gradient may tighten slightly Friday into the weekend as surface high pressure becomes better established over the eastern Gulf while lower pressures persist over the southern Plains and lower Mississippi Valley. This should result in a more consistent south to southwest flow, generally around 10 to 15 knots which will support 2-3 ft seas. Increasing Gulf moisture will also bring a gradual increase in showers and thunderstorms beginning Thursday and continuing through the weekend and into early next week. Convection will be most common, in typical summertime fashion, over the coastal waters during the overnight and morning hours. Then activity shifts inland with the developing sea breeze during the afternoons. $$ |
