Post-Tropical Cyclone Four-E Forecast Discussion Number 8
2019-07-14 16:37:12| National Hurricane Center (East Pacific)
Issued at 800 AM PDT Sun Jul 14 2019 000 WTPZ44 KNHC 141437 TCDEP4 Post-Tropical Cyclone Four-E Discussion Number 8 NWS National Hurricane Center Miami FL EP042019 800 AM PDT Sun Jul 14 2019 Former Tropical Depression Four-E has been producing only small bursts of convection for the past 18 h or so. The system is moving over progressively cooler water and into a more stable air mass, so re-development of organized convection appears unlikely. Thus, the system is being downgraded to a remnant low pressure area. The global models indicate that the remnant low should dissipate by 36 h at the latest, and the NHC forecast follows this scenario. The motion is west-northwestward, or 285/11 kt. A low- to mid-level ridge to the north of the cyclone should cause a turn toward the west later today, with this general motion continuing until dissipation. This is the last advisory issued by the National Hurricane Center on this system. 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 14/1500Z 18.4N 115.7W 25 KT 30 MPH...POST-TROP/REMNT LOW 12H 15/0000Z 18.6N 117.7W 20 KT 25 MPH...POST-TROP/REMNT LOW 24H 15/1200Z 18.6N 119.4W 20 KT 25 MPH...POST-TROP/REMNT LOW 36H 16/0000Z 18.5N 121.1W 20 KT 25 MPH...POST-TROP/REMNT LOW 48H 16/1200Z...DISSIPATED $$ Forecaster Beven
