| #1059252 (Received by flhurricane at: 10:39 AM 29.Aug.2021) TCDAT5 Tropical Depression Ten Discussion Number 6 NWS National Hurricane Center Miami FL AL102021 1100 AM AST Sun Aug 29 2021 The center of the depression has become a little more exposed to the northwest of the deep convection during the past few hours as a result of continued 25-30 kt of northwesterly shear. The latest Dvorak estimates are T2.5 from TAFB and T1.0/2.0 from SAB, so the initial intensity remains 30 kt. The system is expected to continue moving through a region of strong northwesterly to westerly shear for the next 2 days or so, and little to no strengthening is anticipated during that time. However, if the convection is able to remain fairly close to the center, then the system could eke into tropical storm status at any time. After 48 hours, a significant decrease in shear, along with warm waters of 27-28 degrees Celsius, should allow for a steady strengthening trend. The NHC intensity forecast has been nudged upward on days 3 through 5, although much of the guidance is even higher, suggesting that further adjustments could be required in subsequent advisories. The depression is moving northward (350/10 kt) through a break in the ridge created by a large deep-layer trough extending south of Newfoundland over the central Atlantic. This trough, along with a strengthening mid-level ridge over the eastern Atlantic on days 3-5, are expected to keep the cyclone on a curvy northward track during the entire forecast period. There is high confidence in the track forecast given low spread among the track models, and the NHC official forecast generally lies between the TVCA and HCCA consensus aids.
