Category 1 tropical cyclone (Australian scale)
Tropical storm (SSHWS)
DurationNovember 7 – November 11
Peak intensity65 km/h (40 mph) (10-min);

Severe Tropical Cyclone Natalie–Lottie

Category 3 severe tropical cyclone (Australian scale)
Category 1 tropical cyclone (SSHWS)
DurationDecember 1 – December 11

This storm initially formed as Natalie, then moved into the Australian region on the same day. Later, it moved back into the South Pacific and was renamed Lottie.[1] High seas caused the ship Uluilakeba to capsize killing more than 85 people.[2][3] This makes Lottie one of the deadliest tropical cyclones in region in recent decades.[4]
