Post-Tropical Cyclone Teresa Discussion Number   5
NWS National Hurricane Center Miami FL       AL192021
500 PM AST Sat Sep 25 2021

Teresa has continued to consist of just a swirl of low-level clouds
since last night. Although a convective band persists a couple
hundred miles northeast of the low center, the system no longer
meets the definition of a tropical cyclone. Strong
west-southwesterly wind shear should prevent any regeneration of
convection near the center. All of the global models show the
remnant low degenerating into an open trough by Sunday morning.

Teresa has been moving eastward or 090/4 kt during the past 12
hours.  A turn to the northeast is expected within the next couple
of hours as the cyclone moves in the southwesterly flow ahead of a
deep-layer trough.  The northeastward motion should continue until
the low dissipates Sunday morning.
