| #1025438 (Received by flhurricane at: 9:42 AM 15.Nov.2020) TCDAT5 Post-Tropical Cyclone Theta Discussion Number 23 NWS National Hurricane Center Miami FL AL302020 300 PM GMT Sun Nov 15 2020 Theta has run out of theta-e. The cyclone has been without significant deep convection for many hours now and has been gradually spinning down today. It no longer meets the qualifications of a tropical cyclone, so this is the last advisory. The initial wind speed is set to 25 kt per the latest scatterometer pass. The low is meandering this morning. It is expected to be picked up to the north-northeast by the next trough over the northeastern Atlantic, along with an increase in forward speed. The remnants of Theta should gradually lose strength due to strong shear, very dry air and little instability before dissipating in a day or two.
