Long Term
(Tuesday through next Saturday) Issued at 241pm CDT Sunday September 25 2022

Key message:

- Hazardous seas, minor coastal flooding, and an increased risk of rip currents Tuesday through Friday.

Surface high pressure and ridging aloft in wake of the front will cause dry conditions and cooler low temperatures through the weekend. Sunny skies during the day will keep highs near normal, from the upper 80s to lower 90s. Clear skies and calm nigheights will lead to efficient radiational cooling, with lows ranging from the upper 50s over portions of the Coastal Plains to around 70 along the coast through the week.

Wave heigheights and swell periods will begin to increase as early as Wednesday morning with the National Hurricane Center projecting what is now Tropical Storm Ian to enter the eastern Gulf of Mexico as a major hurricane. Swell periods between 10 to 15 seconds are expected Wednesday evening through Thursday evening before decreasing Friday. These long swell periods will likely push water to the dunes and cause minor coastal flooding across the Middle Texas Coast. Wave heigheights of around 10 feet and occasionally higher will cause hazardous seas Wednesday night through Thursday night.

Beach goers and mariners of South Texas should pay close attention to Tropical Storm Ian and future forecasts. A shift to the west will increase impacts along the coast and over the waters, whereas a shift to the east would lessen.

Marine
Issued at 241pm CDT Sunday September 25 2022

Isolated showers and storms will continue over the waters this afternoon with activity tapering off through the evening hours. A frontal boundary will move into the waters through the day Monday providing a weak to moderate offshore flow. Isolated convection is possible again Monday with some activity lingering overnight into Tuesday. Northeasterly winds will strengthen overnight Monday with brief Small Craft Advisory conditions possible. Drier air will move into the coastal waters Tuesday as high pressure builds into the region and provides a moderate northeasterly flow. Small Craft Advisory conditions will be possible Wednesday morning through early Friday morning as wave heigheights build to around 10 feet across the western Gulf of Mexico. Wave heigheights and periods are expected to subside Friday into the weekend.
