Tropical Cyclone Victor (TC Victor) was named by RSMC Nadi on Friday 15 January, located near the Northern Cook Islands. Since then, the cyclone tracked between Niue and the Southern Cook Islands, then turned west and headed past Tonga before finally heading southwest towards New Zealand.
At 1 am Saturday 23 January TC Victor was reclassified by RSMC Nadi as a Tropical Low.

Cyclone Victor is forecast to continue to move southwest towards New Zealand today and pass Raoul Island to the southeast during Monday. As it passes Raoul, Cyclone Victor is expected to undergo a transition from a Tropical Low to a mid-latitude low, which means the winds around the low could re-intensify in some sectors.
Strong winds and some rain are expected as Victor passes Raoul. However, based on the currently available information, damaging winds or significant rainfall accumulations are not expected.
