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.{{Cite web|url=http://www.bom.gov.au/climate/tropical-note/archive/20190312.archive.shtml|title=Weekly Tropical Climate Note|website=Bureau of Meteorology|date=March 12, 2019|access-date=March 8, 2021}} 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.{{Cite web|url=http://www.bom.gov.au/climate/tropical-note/archive/20190319.archive.shtml|title=Weekly Tropical Climate Note|website=Bureau of Meteorology|date=March 19, 2019|access-date=March 7, 2021}}

On March 11, the Bureau of Meteorology (BOM) noted that a tropical low had formed over the Solomon Sea near Papua New Guinea.{{Cite web|url=http://www.bom.gov.au/cyclone/history/Trevor.shtml|title=Tropical Cyclone Trevor|website=Bureau of Meteorology|access-date=March 9, 2021}} The Joint Typhoon Warning Center (JTWC) first issued a Tropical Cyclone Formation Alert (TCFA) at 1:30 UTC on March 15, while the disturbance was located roughly 270 miles east-northeast of Port Moresby, Papua New Guinea. The agency noted that the system was growing a tightening low-level center and deep convection. Within an area of moderate vertical wind shear and warm sea surface temperatures, the low began to strengthen.{{Cite web|url=http://www.australiasevereweather.com/cyclones/2019/tropical_cyclone_trevor.htm|title=Tropical Cyclone Trevor|access-date=March 9, 2021}}

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.{{Cite web|url=https://info.undp.org/docs/pdc/Documents/PNG/DRM%20NAST%20Report,%20TC%20Trevor,%20Goodenough,%20Milne%20Bay.pdf|title=Impacts of Cyclone Trevor on Goodenough Island, Milne Bay Province|publisher=United Nations Development Programme|access-date=January 22, 2019}}

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.{{Cite web | url=http://www.bom.gov.au/cyclone/tropical-cyclone-knowledge-centre/understanding/tc-names/ | title=Naming tropical cyclones | website=www.bom.gov.au | access-date=2024-07-22 | publisher=Australian Government - Bureau of Meteorology}}{{cite web | url=https://community.wmo.int/tropical-cyclone-operational-plans | title=Tropical Cyclone Operational Plans | World Meteorological Organization }}
