A moderate to strong pulse of the Madden–Julian oscillation (MJO) moved into the Maritime Continent during March 2019. This aided the formation of a weak monsoonal trough to the north of Australia, which would help any tropical cyclone located in the area move southward toward the country.[1] Although, the MJO soon weakened and no longer played an influence of tropical weather. This was due to other climate influences overshadowing the weakening MJO. Global forecasting models came into agreement that the MJO would continue to no longer be discernible over Trevor's lifespan.[2]
Trevor caused destruction across Goodenough Island. 591 residences were partially damaged, while 463 residences were fully damaged. A primary school was damaged by high winds, forcing classes to be cancelled for several weeks. On the island, 20% of gardens growing food were damaged by Trevor. The staff houses at a clinic in Yauyaula were mangled. In Kilia Ward, a church was destroyed by powerful winds. Fish ponds on the island were demolished by the cyclone.[7]

Not since Marcia/Lam in 2015 have we had 2 severe cyclones in the Aus region at the same time! #CycloneVeronica in northwest WA is currently Category 4 strength, while #CycloneTrevor in the Gulf of Carpentaria is also likely to intensify to Cat 4 today.
As the storm made landfall on the Cape York Peninsula, the entire town of Coen lost electricity while nearby Aurukun reported isolated power outages.[13] The Iron Range National Park received extensive damage from the storm with numerous trees being flattened.[14]
Retirement
Due to the impact in Northern Queensland caused by the storm, the name Trevor was retired and will never be used again for an Australian region tropical cyclone. It will be replaced by Trung upon the next list repeat.[15][16]
