Post-Tropical Cyclone Trudy Discussion Number  27
NWS National Hurricane Center Miami FL       EP212026
800 PM MST Mon Oct 19 2026
 
Trudy's convection has rapidly vanished over the last 6-9 hours. In 
fact, the latest satellite imagery shows that all deep convection 
associated with Trudy has dissipated, leaving only a weak remnant 
low-level circulation that has become less defined. As a result, 
Trudy no longer meets the criteria of a tropical cyclone, and this 
is the last NHC advisory on this system. The initial intensity is 
estimated at 30 kt assuming additional spin down of the circulation 
from earlier today.  
 
The vortex of Trudy is expected to degrade further as it moves 
slowly in an environment defined by dry mid-level air, increasing 
vertical wind shear, and upper-level convergence. It should be noted 
that diurnally-driven convective pulses are possible over the next 
day or so. However, this activity is expected to remain disorganized 
and insufficient for redevelopment. The remnant low is expected to 
move very slowly to the west-northwest before guidance generally 
agrees in the circulation dissipating within the next 48 hours.
