| #1012435 (Received by flhurricane at: 10:42 PM 15.Aug.2020) TCDAT2 Tropical Storm Kyle Discussion Number 6 NWS National Hurricane Center Miami FL AL122020 1100 PM AST Sat Aug 15 2020 Although Kyle continues to lose its overall tropical appearance, a burst of deep convection redeveloped, albeit sheared to the northeast of the low-level center, which is close enough to the center to still the system classified as a tropical cyclone. ASCAT-A/-B passes at 2333Z/0047Z easily supported winds of 35 kt south through southwest of the center and, allowing for some slight undersampling, the initial intensity has thus been lowered to 40 kt. The initial motion is 075/17 kt. There is no significant changes to the previous track forecast or reasoning. Kyle is expected to continue moving east-northeastward tonight and Sunday morning, maintaining that eastward motion until the cyclone is absorbed into a larger extratropical low in a couple of days. The official forecast similar to the previous advisory track and essentially lies near the center of the NHC track guidance envelope. Kyle`s low-level center is becoming increasingly stretched out northeast-to-southwest and the earlier burst of deep convection has also recently begun to wane, succumbing to 40 kt of westerly deep-layer vertical wind shear. Thus, Kyle is not long for this world, with the cyclone expected to lose all convection within the next 6 to 12 hours, and continue to weaken and degenerate into a post-tropical cyclone Sunday morning. It is highly possible that the next advisory could be the last forecast on Kyle.
