Melanie of late does have some 'mini' cyclone structure about it, compact and not showing the spiralling rain bands we normally see. she does have some large tails to her SW and definitely the flow from the NW top of the NT is evident right down the WA coast into her. BoM have her at 1000hpa on the maps, don't know if that's just being cautious, yet they have her as a CAT3 in the same period?? Perhaps the maps have not been updated as yet.....you'd think they'd be updating the maps considering it's a cyclone ! Thankfully if she does make landfall in the Pilbara it's not too populated - although having said that - when TC George struck three people were killed in the same area.
