Public Advisory not available for this storm.
000 WTNT45 KNHC 290836 TCDAT5 Post-Tropical Cyclone Tammy Discussion Number 40 NWS National Hurricane Center Miami FL AL202023 500 AM AST Sun Oct 29 2023 During the past 18 to 24 hours, Tammy has only been maintaining a small and disorganized patch of deep convection well to the northeast of the fully exposed center. Accordingly, the Dvorak classifications have been decreasing, and the latest estimate from TAFB is a T1.0/2.0. Satellite images also show that the low-level center has become elongated and is losing definition. Based on these characteristics, Tammy no longer qualifies as a tropical cyclone, and this is the last advisory on this system. The initial intensity is held at 35 kt. Tammy is moving eastward at 16 kt in the mid-latitude westerlies. A fairly sharp turn to the south is expected to occur tonight followed by a motion to the southwest on Monday and Tuesday as the post-tropical cyclone moves around the east side of a building subtropical ridge. Tammy is expected to slowly weaken due to continued strong vertical wind shear and dry air entrainment, and it will likely dissipate in a few days.
