Issued at 800 AM PDT Tue Aug 13 2019 000 WTPZ44 KNHC 131433 TCDEP4 Post-Tropical Cyclone Henriette Discussion Number 7 NWS National Hurricane Center Miami FL EP092019 800 AM PDT Tue Aug 13 2019 The system has been devoid of deep convection for about 12 hours, and therefore, it has degenerated into a remnant low. The post-tropical cyclone is moving through an environment of dry, stable air and over cooler SSTs, which should cause the low to dissipate in a day or so. The motion is west-northwestward, or 285/10 kt. A low-level ridge to the north of the system should steer Henriette's remnants on a west-northwestward to westward heading until dissipation. The official track forecast is close to the multi-model consensus, TVCE. This is the last NHC advisory on Henriette. For additional information on the remnant low please see High Seas Forecasts issued by the National Weather Service, under AWIPS header NFDHSFEPI, WMO header FZPN02 KWBC, and on the web at ocean.weather.gov/shtml/NFDHSFEPI.php FORECAST POSITIONS AND MAX WINDS INIT 13/1500Z 21.4N 116.1W 25 KT 30 MPH...POST-TROPICAL 12H 14/0000Z 21.8N 117.8W 20 KT 25 MPH...POST-TROP/REMNT LOW 24H 14/1200Z 22.0N 120.0W 15 KT 15 MPH...POST-TROP/REMNT LOW 36H 15/0000Z...DISSIPATED $$ Forecaster Pasch
