Systems
Tropical Cyclone SP7301
| Category 1 tropical cyclone (Australian scale) | |
| Tropical storm (SSHWS) | |
 | |
| Duration | November 7 – November 11 |
|---|---|
| Peak intensity | 65 km/h (40 mph) (10-min); 990 hPa (mbar) |
Severe Tropical Cyclone Natalie-Lottie
| Category 3 severe tropical cyclone (Australian scale) | |
| Category 1 tropical cyclone (SSHWS) | |
 | |
| Duration | December 1 – December 11 |
|---|---|
| Peak intensity | 120 km/h (75 mph) (10-min); 965 hPa (mbar) |
This storm formed as Natalie, then moved into the Australian region the same day. Later it moved back into the SPac and was renamed Lottie. High seas caused the ship Uluilakeba to capsize killing more than 85 people. This makes Lottie one of the deadliest tropical cyclone in region in recent decades.
