Just after the first anniversary of TC Marcus which flattened so many mahogany trees across Darwin, many residents are hoping perhaps TC Trevor can produce a last hurrah for the wet, minus the wind of course.

But while TC Trevor is tracking west across the top of Queensland, it still has a long way to go before it influences weather in the Top End.

Most weather experts don't expect anything much to happen here until the weekend at least.

Some weather websites are suggesting TC Trevor (by then a tropical low) will take a dive under Katherine and head south but the bureau is not making these predictions yet.

Katherine's march total so far is a measly 29mm against our average of 168mm.

Wet season rain totals across the Top End are between half to two thirds of average.

TC Trevor has developed into a category one system, and is expected to cross the Cape York Peninsula before entering the Gulf of Carpentaria.

The system had moved south from Papua New Guinea as a tropical low before intensifying in the Coral Sea.

TC Trevor is currently located 75 kilometres off the east coast of Queensland and is expected to intensify into a category two before making landfall Tuesday evening.

The whole system is only moving west at about 10kmh.

The cyclone is expected to make landfall on the eastern Cape York Peninsula coast late on Tuesday.

Trevor is expected to be downgraded to a tropical low as it enters the Gulf of Carpentaria on Wednesday and its movements afterwards are unclear.

A cyclone warning and cyclone watch have been issued across the eastern half of Cape York Peninsula, where gale force winds with destructive gusts, abnormally high tides and heavy rain are likely during the coming days. If Trevor reaches category three strength, very destructive wind gusts would also be possible.

If Cyclone Trevor makes landfall as expected, it will briefly lose some strength as it passes over Cape York Peninsula. However, most models suggest that the system will then travel over the Gulf of Carpentaria, where it is likely to re-intensify.

"Cyclones in the Gulf are notoriously erratic and forecast track and intensity may change in coming days," the bureau said.

The bureau advises anyone living in northern areas of Queensland and the Northern Territory should monitor the latest advisories closely by visiting http://www.bom.gov.au/cyclone/ throughout the week.
