In short:

Severe Tropical Cyclone Narelle is expected to intensify into a category four system before making landfall this week.

Communities in its path are being urged to prepare now.

What's next?

It could re-intensify after it crosses the Gulf of Carpentaria and affect the Northern Territory all the way to Western Australia.
