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
