Severe Tropical Cyclone Marcus was a very powerful tropical cyclone that impacted Northern Territory and the Kimberley region in March 2018. It was the strongest tropical cyclone of the 2017–18 Australian region cyclone season and the strongest tropical cyclone in the Australian region since George in 2007. It was also considered the worst cyclone to hit Darwin since Tracy in 1974.[1]

On 15 March 2018, a tropical low formed in the western Arafura Sea.[2] Drifting east-southeastwards north of the Tiwi Islands, the tropical low spun up into a Category 1 tropical cyclone on the Australian scale early on 16 March, and was accordingly given the name Marcus.[3] In a generally favourable environment for intensification, Cyclone Marcus reached Category 2 status in the hours before it crossed the Northern Territory coastline on 17 March.[4]

Marcus intensified markedly upon moving away from the coast and by 21 March, Marcus reached Category 5 intensity.[5]

Impact

Before the storm, on 15 March, the Australian Bureau of Meteorology issued cyclone warnings for Darwin, the Tiwi Islands and parts of the northwest Top End.[7] Major events and flights in and out of Darwin were cancelled.[8] Approximately 26,000 homes were affected by electricity outages as a result of the destructive winds, even in areas as far south as Batchelor and Adelaide River.[9] Thousands of trees were destroyed across the Greater Darwin region including many African mahoganies planted after Cyclone Tracy for their fast growing and expansive shade qualities.[10] [11]

Public schools and non-essential public service agencies were closed while the clean-up efforts continued and tree trunks removed from roads.[9] Cyclone Marcus was the most destructive storm to hit Darwin since Cyclone Tracy, a category 4 cyclone caused devastation on Christmas Eve of 1974.[12]

The cleanup response was coordinated by the Northern Territory Emergency Services and included soldiers from the 5th Battalion and local engineers of the Australian Army. The US Marine Rotational Force – Darwin (MRF-D) also contributed to the clean up effort.[13]
