Queensland's fourth tropical cyclone of the season has formed 440 kilometres northeast of Cairns in the far north.

The category one cyclone formed on Thursday morning and has been named Tim.

Bureau of Meteorology forecaster Pradeep Singh says the cyclone is moving in a east-southeast direction at about 30km/h.

"It may form into a category two system, but at the same time it is moving away from the coast" he told AAP.

He says there is little chance it will reach the mainland, although it will likely bring heavy rain to parts of the northern coastline as it begins to weaken.

Up to 100 millimetres of rain over 24 hours is expected between Cairns and Saint Lawrence, about 900km south of Cairns, at the weekend.

Meanwhile, predecessor Cyclone Sandra is sitting 500km north of Lord Howe Island, 600km off the coast of central NSW.

The cyclone is moving south and is expected to sit 180km from the island on Friday morning.

Mr Singh says residents on the island can expect winds up to 150km/h which may damage homes.

Weather conditions next week are forecast to quieten across Queensland with the easing of monsoonal conditions.

The other cyclones to hit Queensland this season have been Oswald and Freda.
