Synopsis for the Gulf of America

1056 PM EDT Wed Jun 17 2026



.SYNOPSIS...Post-Tropical Storm Arthur remains along the Texas

coast near 29.7N 94.5W at 11 PM EDT, moving northeast at 8 kt. 

Maximum sustained winds are 30 kt with gusts to 40 kt. Minimum 

central pressure is 1000 mb. The weakening remnants of Arthur 

will move northeastward and into SW Louisiana tonight and 

dissipate. Strong thunderstorms occurring well to the E of Arthur 

are offshore of SE Louisiana and will shift NE tonight through 

Thu. S to SW swell generated by Arthur and associated 

thunderstorms are likely to cause large and dangerous surf and 

life-threatening rip current conditions along the northwestern and

north-central Gulf Coast for the next day or two. Otherwise, a 

tightening pressure gradient will develop over the basin tonight 

and sustain fresh to strong southerly winds over the western and 

central Gulf tonight 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.
