Post-Tropical Cyclone Karina Forecast Discussion Number 17

Issued at 800 PM PDT Wed Sep 16 2020 000 WTPZ41 KNHC 170237 TCDEP1 Post-Tropical Cyclone Karina Discussion Number 17 NWS National Hurricane Center Miami FL EP162020 Issued by NWS Central Pacific Hurricane Center Honolulu HI 800 PM PDT Wed Sep 16 2020 Karina has lacked deep convection for sufficiently long to be deemed a post-tropical cyclone, and this is the last NHC advisory. Satellite imagery shows a well-developed low cloud swirl that is estimated to be producing winds to 30 kt, primarily based on an earlier ASCAT pass. Karina is moving northwestward at 8 mph, and although a turn toward the west is expected the next day or so, it will remain over 23C waters. This will prevent the redevelopment of significant convection, and the cyclone is expected to gradually spin down until it becomes a trough and dissipates in a couple days.
