016 WTPZ43 KNHC 082030 TCDEP3 Tropical Depression Terry Discussion Number 18 NWS National Hurricane Center Miami FL EP182021 200 PM MST Mon Nov 08 2021 Although Terry's overall convective organization remains poor, a 1526 UTC ASCAT-A overpass indicated that the circulation was better defined than last evening. The scatterometer data revealed peak winds of 25-26 kt, and given the typical undersampling from that instrument the initial intensity is held at 30 kt for this advisory. Mid-level shear and the ingestion of a drier and stable air mass have continued to take a toll on the cyclone. These conditions are not expected to abate during the next couple of days, and some additional weakening is possible during that time. Although some of the guidance suggests that Terry could reach a more favorable environment later in the period, the ECMWF and UKMET models continue to weaken the system and the NHC forecast again shows the system degenerating into a remnant low by 72 hours and dissipate by day 4. Terry continues to move west-northwestward or 285/13 kt. As stated in the past several advisories, the steering currents ahead of Terry remain well established and there is no change to the forecast track reasoning. The cyclone will continue to move west-northwestward to westward to the south of a strong deep-layer over western Mexico. The latest suite of dynamical model tracks is slightly north of and slower than the previous model envelope. As a result, the official NHC track forecast has been adjusted accordingly, and is a blend of the HFIP corrected consensus (HCCA) and the simple consensus aids.
