Issued at 1100 PM AST Tue Aug 31 2021 000 WTNT45 KNHC 010233 TCDAT5 Tropical Depression Kate Discussion Number 16 NWS National Hurricane Center Miami FL AL102021 1100 PM AST Tue Aug 31 2021 Some bursts of convection have been forming within Kate's small circulation during the past several hours, but none of it has any real significant organization. In addition, the low clouds appear to be losing definition, and a very-recent ASCAT-B pass showed that the maximum winds are now only about 25 kt. It's going to be difficult for Kate to make much of a comeback, if at all. Moderate northerly shear, dry mid-level air, upper-level convergence, and an increasingly anticyclonic low-level environment are likely to cause the circulation to spin down further and make it hard for deep convection to persist. Therefore, the NHC official forecast now calls for additional weakening, with Kate likely becoming a remnant low by 36 hours (if not sooner) and dissipating by 72 hours. This scenario is closest to the GFS, HWRF, and HMON solutions. Located on the southwestern periphery of a low-level area of high pressure, Kate is moving toward the north-northwest (345/9 kt). The depression is forecast to turn toward the northwest by morning, but then recurve around the high toward the north and north-northeast in a couple of days. The NHC track forecast remains close to the consensus aids and is generally just an update from the previous advisory.
