000 WTNT41 KNHC 192034 TCDAT1 Tropical Depression Six Discussion Number 2 NWS National Hurricane Center Miami FL AL062026 900 PM GMT Sat Sep 19 2026 A new burst of convection has formed over the depression, that mostly covers the center of the system. However, the bulk of the convection is still on the northern side of the cyclone at this time, implying that some wind shear is still affecting it. The most recent TAFB Dvorak fix was T2.0/30 kt, which is the same as the previous cycle. Therefore, the initial intensity remains at 30 kt for this advisory. Tropical Depression Six is still moving slowly, but has started to show a bit more motion towards the north-northeast. The cyclone should move more northeastward for roughly the next 36 h as a trough to the north weakens a low- to mid-level ridge to the northeast. Following this, at around 48 h, the ridge should build back towards the west, which in turn will force the cyclone to move southwestward for the rest of the forecast period. The current NHC forecast track is very similar to the previous forecast track with small adjustments to the track and speed, and remains in good agreement with HCCA and GDMI. The cyclone should move into a slightly more favorable environment, between two areas of intense shear, and so there a good chance for intensification to occur for the next day or so. After 36 h, the system should move into an area of higher shear as the previously mentioned trough moves closer. This should lead to a gradual weakening of the system. The depression is expected to become a post-tropical remnant low around 72 h, and then dissipate around 120 h. There is still some uncertainty in the forecast of when the cyclone will become post-tropical and then dissipate, as both could possibly occur sooner than what is currently forecast. The new NHC intensity forecast is still in the middle of the guidance envelope, and is closely align with HCCA and just under GDMI for peak intensity.
