Part of the 1997–98 South Pacific and the Australian region cyclone season

Severe Tropical Cyclone Yali was one of seven severe tropical cyclones to develop during the 1997–98 South Pacific cyclone season. The system that was to become Yali was first noted as a tropical disturbance, to the northeast of Vanuatu during March 17. Over the next couple of days, the system moved towards the south-west and gradually developed further, before it was named Yali during March 19, after it had developed into a tropical cyclone. After it was named Yali re-curved and started moving towards the south-southeast, as the monsoonal flow to the north of the system strengthened. While the system was active, Yali affected Vanuatu and New Caledonia before the extra-tropical remnants impacted New Zealand where a man was killed and widespread power outages and damage were reported.
