Long Term
(Thursday through next Monday) Issued at 218pm CDT Tuesday September 27 2022

-Minor to Moderate Coastal Flooding this week -Increased Rip Current Risk this week -Dangerous boating conditions this week

The main message in the long term is concerning coastal hazards as Major Hurricane Ian churns in the southeastern Gulf. Even though Ian is not forecast to directly impact Texas, increased period swells up to around 12 seconds and increased waves up to around 12 ft are expected to result in hazardous beach conditions including the increased risk for rip currents and minor to moderate coastal flooding. The longer swell periods, in combination with increased wave heights, will result in significant wave run up. Water is expected to reach the dunes and beach access roads may become inundated as well as low-lying areas and structures near the immediate coast. As the swells and waves slowly subside towards the end of the week hazardous conditions may linger over the weekend. So it's important to pay attention to the forecast and be aware of beach conditions before you go.

Jumping back to the overall synoptic pattern for the long term period starts out with a low pressure system over the Pacific Northwest, ridging over the Central CONUS and Hurricane Ian over the southeastern states. The pattern doesn't change much as the ridge gets blocked in by both systems.

One interesting feature that models are forecasting is a storm over the eastern Pacific south of Baja. There's a lot of uncertainty with the track of this feature but the GFS (Global Forecast System) wants to bring the remnant energy towards South Texas early next week. So far the GEFS and ECENS don't have it going that far east and is split on the track of the system. Not surprisingly being this far out so will have to continue monitoring it but not going to put much stock into the GFS solution at this time.

As far as the overall weather pattern, afternoon temperatures throughout the week will range mostly in the 80s with lows in the 50s-60s under mostly clear skies.

Marine
Issued at 412am CDT Tuesday September 27 2022

Dry conditions will prevail through early next week. Small Craft Advisory conditions are expected Wednesday through Thu Night as a result of the combination of moderate flow and high seas due to Hurricane Ian in the far eastern Gulf of Mexico. Moderate northeast flow will become weak to moderate Saturday then weak by Sunday.
