Post-Tropical Cyclone EIGHT-E Forecast Discussion Number 10
2017-07-20 22:34:24| National Hurricane Center (East Pacific)
Issued at 200 PM PDT Thu Jul 20 2017 000 WTPZ43 KNHC 202034 TCDEP3 Post-Tropical Cyclone Eight-E Discussion Number 10 NWS National Hurricane Center Miami FL EP082017 200 PM PDT Thu Jul 20 2017 Satellite imagery indicates that Tropical Depression Eight-E has degenerated to a low pressure area in the Intertropical Convergence Zone, with neither the organized convection nor well-defined circulation of a tropical cyclone. The remnant low is forecast to persist for 48 h and then be absorbed by Tropical Storm Greg passing to the north. While the system will be monitored for signs of redevelopment, the chance of this occurring appears very low at the present time. This is the last advisory issued by the National Hurricane Center on the 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 http://www.opc.ncep.noaa.gov/shtml/NFDHSFEPI.shtml.
