DISCUSSION AND OUTLOOK ---------------------- At 300 PM GMT (1500 UTC), the center of Post-Tropical Cyclone Isaac was located near latitude 44.8 North, longitude 29.1 West. The post-tropical cyclone is moving toward the east-northeast near 17 mph (28 km/h) and a turn to the northeast is expected with a similar forward motion for the next several days. Maximum sustained winds have decreased to near 60 mph (95 km/h) with higher gusts. Gradual weakening is forecast over the next several days. Tropical-storm-force winds extend outward up to 185 miles (295 km) from the center. The estimated minimum central pressure is 983 mb (29.03 inches). HAZARDS AFFECTING LAND ---------------------- SURF: Swells generated by Isaac will affect the Azores over the next few days. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.

This displacement is a result of strong southwesterly vertical wind shear ahead of a central Atlantic upper-level trough. With no recent surface observations or scatterometer wind data available, 30 kt will remain the initial intensity, reflecting the subjective Dvorak analysis from TAFB and SAB. The depression has meandered this morning, and the current motion estimate is an uncertain 360/2 kt. The official track forecast depicts a slow northward motion until Joyce fully dissipates in 48 h, similar to the previous track forecast. Continued shear coupled with persistent dry air should increasingly inhibit organized convection, leading to Joyce degenerating into a remnant low soon. The intensity forecast is similar to the previous one showing Joyce becoming a remnant low in 12 h with total dissipation in about 48 h.

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 AM EDT Mon Sep 30 2024

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

Active Systems:
The National Hurricane Center is issuing advisories on Tropical
Storm Isaac, located several hundred miles north of the Azores, on
Tropical Depression Joyce, located over the central Atlantic Ocean,
and on Tropical Depression Twelve, located over the eastern
tropical Atlantic Ocean.

Western Caribbean Sea and Gulf of Mexico:
A large and disorganized area of low pressure located over the
western and southwestern Caribbean Sea is producing some shower and
thunderstorm activity. Environmental conditions could become
conducive for gradual development, and a tropical depression could
form in a few days while the system is over the southern Gulf of
Mexico or northwestern Caribbean Sea. While interests in the
northwestern Caribbean Sea and along the U.S. Gulf Coast should
continue to monitor the progress of this system, the timetable for
potential development has shifted later toward late week or this
weekend.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...medium...40 percent.

Eastern Tropical Atlantic:
Showers and thunderstorms have increased in association with a
tropical wave located a few hundred miles south of the Cabo Verde
Islands. Upper-level winds are forecast to become more conducive
for gradual development, and a tropical depression is likely to form
in a few days while it moves slowly westward over the eastern
tropical Atlantic.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 7 days...high...80 percent.

&&
Public Advisories on Tropical Depression Twelve are issued under
WMO header WTNT32 KNHC and under AWIPS header MIATCPAT2.
Forecast/Advisories on Tropical Depression Twelve are issued under

Issued at 500 AM AST Mon Sep 30 2024 000 WTNT42 KNHC 300838 TCDAT2 Tropical Depression Twelve Discussion Number 3 NWS National Hurricane Center Miami FL AL122024 500 AM AST Mon Sep 30 2024 Tropical Depression Twelve has become better organized overnight. A 29/2338 UTC ASCAT-B overpass showed a large area of 25 to 30 kt winds, and that the center was located near the northern edge of the large convective mass. Although a 30/0334 UTC AMSR2 microwave image showed that the center was still located near the northern edge of the central convective area, curved banding has been increasing during the night, with a large area of cold cloud tops persisting. Subjective Dvorak intensity estimates are a consensus T-2.0/30 kt from both TAFB and SAB. Objective intensity estimates from UW-CIMSS are rising and now range from 36 to 41 kt. Based on the subjective Dvorak estimates, a 30 kt initial intensity is held for this advisory, but the depression is likely very near tropical storm strength. The estimated initial motion of the depression is westward, or 275/7 kt. The cyclone will continue moving westward to west-northwestward for another couple days while a well-established subtropical ridge remains in place to the north of the system. A gradual turn to the northwest is expected around mid-week as a deep-layer trough over the north-central Atlantic weakens the ridge. At the end of the forecast period, an approaching upper-level trough near Bermuda will induce the cyclone to turn northward over the open waters of the central Atlantic Ocean. Some along-track spread is noted in the various track model solutions, but the models are in good agreement on the northward turn, with little cross-track spread. The latest NHC track forecast is nearly identical to the previous one, and is about halfway between the slower GFS solution and the faster ECMWF model. Conditions are quite favorable along the path of the depression with 29 degree C sea-surface temperatures, a moist environment, and weak vertical wind shear. Given the weak shear and the gradually improving structure, the cyclone should begin to steadily intensify soon. The depression is forecast to become a hurricane in 36 to 48 hours and a major hurricane in about 4 days. The NHC intensity forecast is similar to the previous one, and lies between the middle and upper end of the intensity guidance suite, near the HCCA and IVCN multi-model consensus aids. It should be noted that most of the models indicate that the cyclone's wind and wave field will expand significantly over the next several days, and the system is forecast to become a large and powerful hurricane as it gains latitude later this week.
