Synopsis for the Gulf of America

1049 PM EDT Sun Aug 30 2026



.SYNOPSIS...A 1012 mb low press (Invest AL97) is located in the

north-central Gulf waters producing scattered showers and isolated

thunderstorms. The low has become better defined and continued gradual 

development is expected as the low moves slowly west-northwestward, 

and a short-lived tropical depression or tropical storm is likely to 

form before the system reaches the Upper Texas or southwestern 

Louisiana coasts on Tuesday or Tuesday night. Interests along the

southwest Louisiana and Upper Texas coasts should monitor the 

progress of this system, as tropical storm watches or warnings 

could be required for portions of the area later tonight or Monday

morning. Regardless of development, this system is expected to 

bring locally heavy rainfall to portions of the Upper Texas and 

southwestern Louisiana coasts during the next several days. There

is a high chance of tropical formation of this low pressure over 

the next 48 hours. Elsewhere, weak high pressure will persist 

through the forecast period, sustaining moderate or weaker winds 

and slight seas. Winds will pulse to fresh with moderate seas off 

western Yucatan during the evenings due to a diurnal surface 

trough moving west off the peninsula each night.
