It is forecast to make landfall today near Lockhart River BOM warns there is the potential for destructive winds, heavy rainfall, and abnormally high tides

The Bureau of Meteorology (BOM) said the cyclone was now a category two, and was rapidly intensifying into a category 3 as it moved towards the Far North Queensland coast.

BOM senior forecaster Gabriel Branescu said the system was expected to cross the coast south of Lockhart River as a category three cyclone on Tuesday.

"The system is forecast to bring destructive winds to eastern parts of the peninsula as it makes landfall during Tuesday evening, with wind gusts above 125km per hour," Ms Branescu said.

"Also the system is forecast to bring abnormal high tides on Tuesday morning and Wednesday morning over parts of the eastern peninsula, and also heavy rainfall (and) possible flash flooding.

"As a result we have a flood watch in place extending from Cairns to Kowanyama."

Mr Branescu said rainfall totals of between 200 and 400 millimetres were expected over coming days in areas between Cairns and Cooktown.

He said Cyclone Trevor was expected to head towards the Northern Territory after crossing the Cape before heading out to sea.

"From [the] Gulf of Carpentaria the system is forecast to move towards [the] south-west, and forecast to re-intensify and reach category-one cyclone strength again during Thursday."
