Post-Tropical Cyclone Gil Forecast Discussion Number 7
2019-08-05 04:36:40| National Hurricane Center (East Pacific)
Issued at 800 PM PDT Sun Aug 04 2019 000 WTPZ43 KNHC 050236 TCDEP3 Post-Tropical Cyclone Gil Discussion Number 7 NWS National Hurricane Center Miami FL EP082019 800 PM PDT Sun Aug 04 2019 Gil has lacked significant organized deep convection for more than 12 hours. Therefore, the depression has been downgraded to a post-tropical remnant low. Although the system may still produce some sporadic, nonpersistent convection into early Monday, dry and stable air along with strong northwesterly shear will likely prevent any appreciable convection from developing over the next couple of days. This should cause the remnant low to weaken and then open into a trough within the next 24-36 hours. The initial motion estimate is 270/10 kt. The remnant low is expected to move westward tonight then west-southwestward on Monday, steered by the low-level environmental flow. This west-southwestward motion should continue until the low dissipates. This is the last advisory 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 05/0300Z 15.1N 127.3W 25 KT 30 MPH...POST-TROPICAL 12H 05/1200Z 15.0N 128.8W 20 KT 25 MPH...POST-TROP/REMNT LOW 24H 06/0000Z 14.6N 130.8W 20 KT 25 MPH...POST-TROP/REMNT LOW 36H 06/1200Z...DISSIPATED $$ Forecaster Latto/Pasch
