Post-Tropical Cyclone Ignacio Forecast Discussion Number 10
2021-08-04 04:36:54| National Hurricane Center (East Pacific)
Issued at 800 PM PDT Tue Aug 03 2021 000 WTPZ45 KNHC 040236 TCDEP5 Post-Tropical Cyclone Ignacio Discussion Number 10 NWS National Hurricane Center Miami FL EP102021 800 PM PDT Tue Aug 03 2021 Ignacio consists of a swirl of low-level clouds and has been devoid of deep convection anywhere near its center since this morning. Therefore the system no longer qualifies as a tropical cyclone and is now a remnant low, or a post-tropical cyclone. The low has been moving east-southeastward, or about 120/6 kt. A turn toward the southeast and south is expected on Wednesday while the system moves around the northern side of a low-level ridge. Although the low will be moving over slightly warmer waters, strong easterly shear should prevent regeneration, and the system should dissipate in 24 h or so. This is the last advisory issued by the National Hurricane Center on Ignacio. 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 04/0300Z 20.1N 115.0W 25 KT 30 MPH...POST-TROPICAL 12H 04/1200Z 19.6N 114.6W 20 KT 25 MPH...POST-TROP/REMNT LOW 24H 05/0000Z...DISSIPATED $$ Forecaster Pasch
