Because there has largely been little change in the system's organization, and there is quite a range among the subjective and objective estimates, the intensity remains 30 kt out of respect for continuity. The initial motion is a little slower toward the west-northwest (290/12 kt). A weakness in the subtropical ridge to the north of the depression is becoming more pronounced, and the track guidance indicates that the system should turn westward by tonight and slow down further through much of the forecast period as it moves across the central tropical Atlantic. In fact, by days 4 and 5, an amplifying shortwave trough to the north is likely to cause the cyclone to crawl at speeds near or less than 5 kt and gradually turn northwestward. The official forecast is close to the previous prediction during the first 60 hours, but then is adjusted westward on days 3 through 5 following the latest model trends. In terms of moisture, the environment across the tropical Atlantic has not been kind to weather systems over the past couple of months. The official forecast still allows for the possibility of the depression becoming a tropical storm today or tonight, however an even drier air mass to the west is likely to cause the cyclone to continue struggling convectively. In fact, all of the global models show the cyclone's wind field weakening over the weekend, with the GFS suggesting the depression could degenerate into a remnant low. For now, the NHC forecast keeps the system as a tropical cyclone for the entire forecast period, but it does show weakening in a couple of days. Some recovery is possible by days 4 and 5 when the system reaches a slightly more moist and low-shear environment.

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 AM EDT Fri Sep 13 2024

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

Active Systems:
The National Hurricane Center is issuing advisories on Tropical
Depression Seven, located over the central tropical Atlantic Ocean.
The Weather Prediction Center is issuing advisories on Post-Tropical
Cyclone Francine, located inland over northeastern Arkansas.

Near the Northern Leeward Islands (AL94):
Satellite-derived wind data from several hours ago indicate that
a small area of low pressure located less than one hundred miles
east of the northern Leeward Islands has degenerated into a surface
trough. Environmental conditions, including the proximity of dry
air, do not favor development of this system while it moves
west-northwestward at about 15 mph. Regardless of development,
locally heavy rainfall and gusty winds are possible across the
northern Leeward Islands today.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 7 days...low...20 percent.

Offshore the Southeastern U.S.:
A non-tropical area of low pressure could form along a frontal
boundary a few hundred miles off the southeastern U.S. coastline
this weekend. Thereafter, some subtropical or tropical development
is possible during the early part of next week while the system
moves generally northwestward toward the coast.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...low...30 percent.

Issued at 1100 PM AST Thu Sep 12 2024 491 WTNT42 KNHC 130253 TCDAT2 Tropical Depression Seven Discussion Number 7 NWS National Hurricane Center Miami FL AL072024 1100 PM AST Thu Sep 12 2024 The depression has been holding steady this evening. After a lull in the convective activity which exposed the low-level circulation, thunderstorms have been building steadily to the east of the center. Unfortunately, the scatterometer pass missed the core of the system once again. The initial intensity remains at 30 kt, close to the subjective Dvorak estimates from TAFB and SAB. A subtropical ridge to the north of the depression is steering the system west-northwestward at about 14 kt. As the ridge weakens during the next few days, the cyclone should gradually slow and turn more westward. There is still a large spread in the track guidance envelope early next week, which seems partially related to the depth of the vortex. The ECMWF solution shows a much stronger system that turns the cyclone to the north sooner compared to the GFS and GFS-based regional models showing a weaker system that moves faster and stays in the low-level westerly flow. The latest NHC track forecast has been nudged a little to the south and lies between the previous prediction and the consensus aids. Marginal environmental conditions appear to be preventing the depression from making any appreciable intensity changes. Visible satellite imagery from earlier today showed a band of Saharan dust wrapping around the northern semicircle of the circulation. The intensity guidance has shifted downward again this cycle, with many models showing a steady-to-weakening system over the next 3-4 days. By the end of the forecast period, there is quite a bit of spread in the intensity guidance as noted earlier. The latest NHC intensity forecast has been decreased slightly but remains on the high side of the various aids.

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

Active Systems:
The National Hurricane Center is issuing advisories on Tropical
Depression Seven, located over the central Atlantic Ocean. The
Weather Prediction Center is issuing advisories on Post-Tropical
Cyclone Francine, located inland over the Mississippi, Missouri,
and Tennessee tri-state area.

East of the Leeward Islands (AL94):
Scattered showers and thunderstorms continue in association with a
small area of low pressure located a couple of hundred miles east of
the Leeward Islands. The proximity of dry air near the system is
expected to limit additional development over the next couple of
days. Environmental conditions are expected to become even less
conducive over the weekend while the system moves slowly
west-northwestward. Regardless of development, this system could
produce locally heavy rainfall and gusty winds across the northern
Leeward Islands on Friday.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 7 days...low...30 percent.

Offshore the Southeastern U.S.:
A non-tropical area of low pressure could form along a residual
frontal boundary a few hundred miles off the southeastern U.S.
coastline this weekend. Thereafter, some subtropical or tropical
development is possible during the early part of next week while the
system drifts to the north or northwest.
* Formation chance through 48 hours...low...near 0 percent.

Subjective and objective Dvorak numbers indicate the system is close to becoming a tropical storm. However, the initial intensity will stay 30 kt, at the lower end of the estimates, until we get a little more definitive evidence of a tropical storm. The cyclone continues on a west-northwestward heading, and the general motion is expected to continue over the next 2-3 days. The forward speed should gradually slow as the subtropical ridge to the north of the system weakens. Track guidance diverges considerably early next week, related to uncertainties with an amplifying trough over the north-central Atlantic Ocean and another ridge centered northeast of the Leeward Islands. The GFS-based guidance has trended much farther west and faster, showing a weakening system at long range. However, the ECMWF and its ensemble members still show a risk of a stronger system, so the forecast will stay on the northeastern side of the track guidance. The new NHC forecast is faster and left of the previous one owing to the bulk of the guidance shifts during this cycle. While environmental conditions are somewhat favorable for gradual strengthening, with low-moderate vertical wind shear and marginally warm SSTs, intensity guidance is even lower than the last cycle. Slight strengthening seems most probable within the marginal environment, and the forecast continues to show a 45-kt peak in 5 days. There is also the potential for greater strengthening beyond what is shown early next week as the cyclone will be in an environment characterized by lower shear, warmer SSTs around 28C, slightly more instability, but plentiful dry air aloft. The latest intensity forecast is very similar to the previous one, on the high side of the guidance envelope.
