Category 1 tropical cyclone (Australian scale)
Tropical storm (SSHWS)

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]
