Tropical cyclone Fina has formed off the Top End as a category 1 storm system and is expected to intensify to category 2 before making landfall or just petering out.
A tropical low off the coast intensified overnight and was classified as a tropical cyclone early on Wednesday morning, Bureau of Meteorology (BoM) senior meteorologist Miriam Bradbury said.
It was moving very slowly east-northeast at about 9km/h and was about 300km to the north-northeast of Darwin.
Bradbury said it was uncertain whether Fina would make landfall.
The cyclone is anticipated to keep its course away from the Northern Territory coastline in the days ahead, with projections suggesting it could intensify to a category 2 level by Thursday afternoon.
It’s then expected to head south or south-west back towards the NT coast.
“A coastal crossing might occur over the weekend or possibly at the beginning of next week,” Bradbury mentioned in an audio release.
Coming days to reveal cyclone’s impact
There were a range of possibilities as to what Fina might do, including avoiding a coastal crossing and “petering out”.
NT communities were not expected to be directly impacted by Fina within the next two days, with forecast showers and thunderstorms, “just normal build-up season weather”, Bradbury said.
When the risk of gales develops along the NT coast over the next two days, the bureau will issue a tropical cyclone watch, flagging the possible dangers.
The BoM’s latest tracking map has Fina making landfall west of Minjilang early on Saturday before heading towards the Tiwi Islands.
Darwin has not experienced a cyclone since category 2 system Marcus cut power to nearly 29,000 properties in March 2018.
In December 1974, Cyclone Tracy flattened Darwin and killed 66 people.
