Issued at 1100 PM AST Sun Sep 20 2020 000 WTNT43 KNHC 210233 TCDAT3 Remnants Of Wilfred Discussion Number 11 NWS National Hurricane Center Miami FL AL232020 1100 PM AST Sun Sep 20 2020 Northwesterly vertical wind shear has continued to take a toll on Wilfred. Recent infrared satellite imagery along with scatterometer data indicate that Wilfred's low-level circulation has become an open trough of low pressure. Therefore, Wilfred is no longer a tropical cyclone and this will be the last NHC advisory on this system. The remaining deep convection has a linear shape and appears to be the result of the system interacting with an upper-level trough to its northwest. The scatterometer data revealed peak winds of close to 30 kt to the north of the trough axis, and that is the basis for the initial intensity. The system is moving generally westward at about 15 kt. The trough should continue to move westward at a slightly slower forward speed until it weakens and dissipates within a few days. This is the last NHC advisory on Wilfred. Additional information on the remnants of this system can be found in High Seas Forecasts issued by the National Weather Service, under AWIPS header NFDHSFAT1, WMO header FZNT01 KWBC, and online at ocean.weather.gov/shtml/NFDHSFAT1.php FORECAST POSITIONS AND MAX WINDS INIT 21/0300Z 15.9N 47.4W 30 KT 35 MPH 12H 21/1200Z...DISSIPATED $$ Forecaster Brown [ more ]
