Centre (TCWC) in Darwin initiated gale warnings for the tropical low, but it was upgraded to Tropical Cyclone Bonnie six hours later, east of Timor. Bonnie was moving west-southwestwards and made landfall on the Timorese coast on 10 April. The cyclone entered TCWC Perth's area of warning responsibility as it moved west of 125°E. Land interaction inhibited the storm from developing, but the cyclone later moved into the Savu Sea where good outflow enabled the storm to strengthen. Bonnie later moved over the south coast of Sumba on 11 April where the land mass weakened the storm again. After moving over water for the second time on 12 April, TCWC Perth and the JTWC increased Bonnie's peak winds to . Bonnie continued to move west-southwestwards but the storm began to slowly weaken as its deep convection decreased and interacted with the island of Java. TCWC Perth issued its last gale warning on Bonnie late on 14 April. The JTWC continued to issue advisories on the low until late on 15 April south-southeast of Cocos (Keeling) Islands. Bonnie caused heavy rainfall and gusty winds in Timor and Sumba. Flash flooding in Sumba killed 19 people. Bonnie also caused a moist northeast wind flow that triggered above average rainfall to northern Western Australia. Tropical Cyclone Errol Briefly attained tropical cyclone intensity 9–10 May north of Cocos Islands, and later passed to their east on 15 May as a weak tropical low. Tropical Cyclone Upia On 23 May a mass of convection north of Bougainville Island developed a well-defined mid-level circulation and broad low-level circulation. The center remained partially exposed for two more days until JTWC issued a Tropical Cyclone Formation Alert, placing the center about 100 nm south of the island. On 25 May, the storm was upgraded by the unofficial agency to Tropical Cyclone 25P. The waters around Papua New Guinea were part of the limited area of responsibility of TCWC Port Moresby. When the cyclone was located near Eastern Milne Bay Province they named the tropical cyclone Upia. Upia was the first system named by the TCWC at Port Moresby since Tropical Cyclone Adel in May 1993. That night and into the early hours of the 27th, the storm caused havoc on Budibudi Island. All coconut trees – including those on adjacent islands – were flattened. Food crops on a nearby island used for agriculture were ruined by the surges.
