Synopsis for the Gulf of America

447 PM EDT Tue Oct 6 2026



.SYNOPSIS...Newly Formed Tropical Depression Nine is near 22.1N 

95.6W, or about 330 nm W of Progreso, Mexico at 5 PM EDT, and is 

moving east at 4 kt. Maximum sustained winds are 30 kt with gusts 

to 40 kt, and the minimum central pressure is 1007 mb. Tropical 

Depression Nine will strengthen to a tropical storm near 22.1N 

95.0W late tonight with maximum sustained winds 35 kt gusts 45 kt,

will track to near 22.6N 93.4W Wed afternoon, to near 23.1N 91.8W

late Wed night with maximum sustained winds 55 kt gusts 65 kt, 

strengthen to a hurricane near 24.2N 90.1W Thu afternoon with 

maximum sustained winds 70 kt gusts 85 kt, then track to near 

25.9N 88.8W late Thu night and to near 28.5N 88.3W Fri afternoon 

with maximum sustained winds 85 kt gusts 105 kt. Nine is forecast 

to weaken to a tropical depression while moving well inland near 

34.0N 88.7W Sat afternoon. Long-period swells generated by the 

tropical cyclone will spread across most of the basin through 

early Sun. Atlantic high pressure will build southwestward toward 

the eastern Gulf in the wake of Nine. Elsewhere, fresh to locally 

strong NW to N winds will follow a trough along the E Mexican 

offshores through Wed night. Weak surface ridging over the NE Gulf

will slowly shift eastward this evening ahead of a stationary 

front over the norther Gulf. The front will gradually weaken Wed 

and Wed night. Fresh to strong NE to E winds and building seas are

N of the front over the NE Gulf.
