The Bureau of Meteorology says the chance of Tropical Cyclone Oma making landfall on the southern Queensland coast is decreasing.

The category-two system is currently 960 kilometres north-east of Brisbane and is still moving towards the city.

BOM forecaster Michael Knepp says there is still a lot of uncertainty about Oma’s movements, but the likely scenario is that it will stay off-shore during the weekend and may possibly move parallel to the coast to the north-east, bringing along gale-force winds.
