Cyclone Narelle has reached Category 5 on the Australian tropical cyclone intensity scale, which is the highest and most severe category.

Quick Scoop: What category is Cyclone Narelle?

  • Cyclone Narelle intensified over the Coral Sea and reached Category 5 on the Australian scale, the top level used for tropical cyclones in the region.
  • Category 5 on this scale means extremely destructive winds, with peak sustained winds well above 200 km/h and much higher wind gusts.
  • Some international reporting also describes parts of Narelle’s life using hurricane-style categories (for example, “equivalent to a Category 4 hurricane” on the Saffir–Simpson scale), but within Australia it is treated as a Category 5 system at peak intensity.

A bit of context

  • On the Australian scale, Category 5 cyclones are rare and represent the most intense and destructive storms, similar in status to Category 5 hurricanes in the Atlantic.
  • Forecasts and expert briefings in March 2026 describe Narelle as an “incredibly powerful” Category 5 cyclone expected to weaken slightly only as it nears or crosses land.

In short, if you’re seeing current news alerts about Narelle, they’re referring to it as a Category 5 tropical cyclone on the Australian scale at its peak.

TL;DR: Cyclone Narelle is a Category 5 tropical cyclone on the Australian scale at peak intensity, the highest and most dangerous category.
