North Queensland coastal communities are no longer under threat from Tropical Cyclone Niran.

The cyclone intensified to a category 3 this morning, but it is currently 345 kilometres north-east of Cairns and is slowly heading further away from the mainland.

The cyclone has caused flash flooding and heavy rain in the region. 

It is likely to reach peak intensity over the Coral Sea on Friday, then gradually weaken as it moves further south-eastwards.
