Post-Tropical Cyclone Iselle Discussion Number  18
NWS National Hurricane Center Miami FL       EP142020
300 PM MDT Sun Aug 30 2020

Iselle hasn't produced organized deep convection for about the past 
day, so it no longer meets the definition of a tropical cyclone.  
Thus, it is now a post-tropical remnant low, and this is the last 
advisory. The initial wind speed is set to 25 kt, which matches a 
recent ASCAT-B pass.  Models are in good agreement on the low 
gradually turning from its current northward heading to north- 
northwest tomorrow and slowly weakening due to a poor environment.  
The low is expected to degenerate into a trough of low pressure on 
Tuesday, and no changes were made from the previous forecast.
