Issued at 200 PM PDT Sat Oct 03 2020 000 WTPZ43 KNHC 032046 TCDEP3 Hurricane Marie Discussion Number 19 NWS National Hurricane Center Miami FL EP182020 200 PM PDT Sat Oct 03 2020 Marie is finally beginning to show signs of weakening. Recent GOES-17 infrared satellite imagery indicates cloud tops are warming in the western eyewall, and water vapor imagery shows drier air impinging on the western periphery of the storm. Despite this, there is still deep convection with cloud tops colder than -70 degrees Celsius persisting in the eastern eyewall. The initial intensity is slightly lowered to 110 kt with this advisory based on a blend of TAFB and SAB Dvorak classifications and a 16 UTC SATCON estimate of 114 kt. Marie is likely beginning to experience increased deep-layer southwesterly wind shear as it moves toward the 26 degree Celsius sea surface temperature isotherm. With environmental conditions becoming increasingly hostile, Marie is expected to steadily, and perhaps rapidly, weaken over the next several days. Marie is forecast to weaken into a tropical storm within 36 hours, as the storm moves over cooler waters and into an environment with 30 kt of vertical wind shear. Steady weakening should continue through early next week, and the system is expected to become a tropical depression by Wednesday and a remnant low on Thursday. Now that the system is finally weakening, the latest NHC intensity forecast reflects a more rapid downward trend supported by the model consensus aids. Marie's initial motion is 325/8 kt, slightly more northwestward than the previous advisory. Marie should continue moving northwestward or west-northwestward for the next several days along the southwest periphery of a mid-level ridge centered over the southwestern United States. The latest model guidance remains tightly clustered during the first 2-3 days of the forecast. Then, the bulk of the guidance indicates Marie will slow down and turn more northward late next week ahead of a deep-layer trough to the north of the storm. Given this recurving scenario, there is more significant spread in the guidance at day 4 and beyond, with the GFS still farther to the right than most other models. Overall, the official NHC track forecast has been adjusted slightly right of the previous one in agreement with the TVCE/HCCA aids.
