Synopsis for the Gulf of America

446 AM EDT Sun Aug 30 2026



.SYNOPSIS...A 1015 mb low pres south of the mouth of the

Mississippi River is producing scattered showers and a few

thunderstorms across the north-central Gulf waters. Some slow

development of this system is possible during the next few days 

as it drifts westward across the northern Gulf. Regardless of 

development, mariners over the northern Gulf waters can expect 

thunderstorms with gusty winds and locally higher seas over the 

next few days. 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.
