Tropical Cyclone Kelvin struck Northwestern Australia with winds reaching 54 knots as it crossed the Kimberley Coast. It brought flooding rains and damaging winds to the settlements and mining companies of the region. The storm intrigued meteorologists as it only developed a cloudless eye after making landfall, believed in part due to the heat flux generated by the warm desert the storm traveled over.

It still contained strong tropical strong force winds with occasionally heavy rainfall. New Zealand's South Island was the hardest hit. The northern end of of the South Island was in the right front quadrant of the tropical cyclone where the wind speeds around the center of circulation were increased by the low's speed of movement.

Tropical cyclone GITA recently battered and drenched first Samoa and then Tonga as it passed close to both island groups. GITA was a tropical storm with winds of about 40 kts (46 mph) when it passed to the south of Samoa but still caused widespread destruction and flooding. The president of the United States approved a disaster declaration for Samoa. The tropical cyclone's winds had increased to about 125 kts (144 mph) when it battered Tonga as the equivalent of a category four hurricane on the Saffir-Simpson hurricane wind scale.
