Synopsis for the Gulf of America

345 PM EDT Sun Aug 30 2026



.SYNOPSIS...A 1014 mb low pressure centered about 100 nm south of

the mouth of the Mississippi River is producing scattered

thunderstorms and has become better organized since this weekend.

Additional development is possible as the low moves slowly west-

northwest and a short-lived tropical depression or tropical storm

could form before the system reaches the Upper Texas or SW

Louisiana coasts Tue or Tue night. Regardless of development, 

mariners over the north-central and northwest Gulf can expect 

strong thunderstorms with gusty winds and locally higher seas 

early this week. There is a medium 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.
