Post-Tropical Cyclone Cristobal Discussion Number   5
NWS National Hurricane Center Miami FL       AL032026
300 PM GMT Thu Aug 13 2026
 
Cristobal is entrenched in a hostile environment, with cool SSTs, 
strong northerly vertical wind shear and dry mid-level air. 
Organized convection has been absent since around 21-22z yesterday 
and all that remains is remnant low devoid of convection. The 
initial intensity is set at 25 kt for this advisory.

The remnant low will continue moving rapidly northeastward to 
east-northeastward today before the remnant low becomes absorbed 
into the broader flow associated with a deepening upper-level low 
over Atlantic Canada. This is the last advisory issued by the 
National Hurricane Center on this system.
