Full Alert Message

Post-Tropical Cyclone Four-E Discussion Number 4 NWS National Hurricane Center Miami FL EP042020 300 PM MDT Tue Jun 30 2020 Satellite images show that the cyclone continues to lack organized convection, and thus no longer meets the requirements of a tropical cyclone. The system is now post tropical, and this is the last NHC advisory. The initial wind speed is 25 kt, perhaps generously, based on continuity. The low should weaken and degenerate into a trough of low pressure due to cool waters during the next day or so while it moves slowly northwestward. 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 FORECAST POSITIONS AND MAX WINDS INIT 30/2100Z 20.9N 112.9W 25 KT 30 MPH...POST-TROPICAL 12H 01/0600Z 21.0N 113.0W 20 KT 25 MPH...POST-TROP/REMNT LOW 24H 01/1800Z 21.2N 113.2W 20 KT 25 MPH...POST-TROP/REMNT LOW 36H 02/0600Z 21.4N 113.5W 15 KT 15 MPH...POST-TROP/REMNT LOW 48H 02/1800Z...DISSIPATED
