MARINE
Issued at 1149 AM CDT Tue Aug 4 2026

No significant marine impacts expected through the forecast period.
A weak pressure gradient will remain in place through much of the week as broad upper level troughing persists over the eastern half of the country and the western periphery of the subtropical ridge is positioned across the Gulf. This will generally support light and somewhat variable winds through Thursday, with speeds mostly 10 knots or less and seas around 1 to 2 feet. Local landbreeze setup may produce a brief offshore wind component during the overnight and early morning hours, followed by a more southerly seabreeze component near the coast each afternoon.

The low-level pressure gradient may tighten modestly 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.
