| #1145146 (Received by flhurricane at: 11:02 AM 24.Jul.2023) TCDAT5 Post-Tropical Cyclone Don Discussion Number 42 NWS National Hurricane Center Miami FL AL052023 300 PM GMT Mon Jul 24 2023 Satellite imagery shows that Don lacks sufficient deep convection to classify the system as a tropical cyclone, and it is now post tropical. The initial wind speed remains at 40 kt for this advisory, based on a recent ASCAT-B scatterometer pass. Don should slowly weaken over the next day or so while moving over cold waters and within high vertical wind shear. The system is moving east-northeastward at about 17 kt, and this general motion will likely to continue until Don dissipates in about a day. Most of the global guidance has post-tropical Don opening up into a trough and becoming absorbed by a larger extratropical low over the north Atlantic tomorrow. Very few changes were made to the previous NHC forecast. Don has been a very long-lasting tropical cyclone (including subtropical stages) for the month of July. Preliminary data indicate that the storm is the 5th longest-lasting system on record for the month, just behind Emily of 2005. This is the last advisory on Don.
