000 WTPZ42 KNHC 271431 TCDEP2 Post-Tropical Cyclone Kristy Discussion Number 24 NWS National Hurricane Center Miami FL EP122024 800 AM PDT Sun Oct 27 2024 Very strong southwesterly vertical wind shear, dry air entrainment, and cool waters have taken a toll on Kristy. The storm has lacked organized deep convection since about 03Z, and it has generally consisted of a low-level cloud swirl since that time. Therefore, Kristy no longer meets the criteria of a tropical cyclone, and this is the last advisory on this system. The initial wind speed is lowered to 40 kt, assuming some decrease in winds from the ASCAT pass overnight that showed maximum winds close to 50 kt. The gale-force low is still moving north-northwestward at about 7 kt, but it is expected to turn to the west and west-southwest later today and Monday when it moves in the low-level flow. The post-tropical cyclone is also expected to continue to weaken and dissipate completely on Monday. This is the last NHC advisory on Kristy. For more details on this system, including gale warnings, see High Seas Forecasts issued by the National Weather Service.
