Post-Tropical Cyclone Teresa Discussion Number 5

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.
