Track of TC 22s

Tropical Cyclone Victoria (22S) will continue tracking poleward throughout the forecast period along the western periphery of the deep-layered subtropical ridge to the east and ahead of an approaching mid-latitude trough.

The favorable upper-level conditions will now begin to deteriorate as vertical wind shear significantly increases ahead of the trough. Additionally, passage over cooler water south of 20 degrees south will contribute to the erosion of the system, leading to its eventual dissipation by TAU 72. Numerical model guidance is in good agreement through TAU 48 and diverges thereafter due to different depictions of the dissipation.
