Synopsis for the Gulf of America

1102 AM EDT Wed Jun 17 2026



.SYNOPSIS...Tropical Storm Arthur is near 28.6N 95.8W at 11 AM EDT, 

and is moving northeast at 8 kt. Maximum sustained winds are 35 

kt with gusts to 45 kt, and the minimum central pressure is 1001 

mb. Arthur will weaken to a tropical depression near 30.0N 94.2W 

this evening, become a remnant low and move to 31.9N 91.6W Thu 

morning, and dissipate Thu evening. Swells generated by Arthur 

are likely to cause life-threatening surf and rip current 

conditions along the northwestern Gulf Coast for the next couple 

of days. Otherwise, a tightening pressure gradient will develop 

over the basin and sustain fresh to strong southerly winds over 

the western and central Gulf late today through Thu night, and 

moderate to fresh winds over the eastern Gulf. Winds and seas will

begin to diminish late Fri through the weekend as weak high 

pressure settles over the eastern Gulf.
