On March 15, a tropical low formed on the Solomon Sea, to the east of Papua New Guinea. Over the next couple of days, the tropical low moved to the southeast, crossing over the southeastern portion of Papua New Guinea on March 16, south of Port Moresby, and then turning southward on March 17. Late on the same day, the tropical low organized into Tropical Cyclone Trevor. Trevor intensified rapidly to a category 3 severe tropical cyclone before crossing the Queensland coast just south of Lockhart River. The cyclone slowed down before turning towards the southwest as it attained category 4 intensity over the warm waters of the Gulf towards the Northern Territory coast. On March 23, it made its second landfall near the Northern Territory/Queensland Border and was subject to weakening. It rapidly degraded inland and it was last noted near Richmond on the afternoon of March 26.[1]

Preparations and impact

Papua New Guinea and Indonesia

In Papua New Guinea, a strong wind warning was put in effect for coastal areas between the Gulf of Papua and the Torres Strait.[2] Due to the wet weather Trevor brought to Port Moresby, the first day of the 2018–19 ICC T20 World Cup East Asia-Pacific Qualifier had to be delayed.[3]

In neighboring Indonesia, heavy rainfall partially associated with Trevor caused flash flooding and mudslides in the province of Papua on 16 March.[4] These floods displaced more than 5,000 people in the province. In Sentani, nine homes were swept away.[5] Numerous residences, three bridges, and a Twin Otter plane were damaged by the flash floods.[6] The floods and mudslides killed a total of 113 people.[7]

Australia

As a precaution, roughly 1,400 people were forced to evacuate to shelters in rural parts of the Northern Territory.[8] This was the largest evacuation in the area since Cyclone Tracy in 1974.[9] A state of emergency was issued for the territory on 21 March.[10] The Carpentaria Highway, Roper Highway, Barkly Stock Route, and the Tablelands Highways were shut down.[11]

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.

22 Mar 2019[12]

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]
