What happened

The apocalyptic red skies in Western Australia have generated considerable international media attention.

Why it matters

Crimson dust whipped up by the strong outer winds of Severe Tropical Cyclone Narelle created this unusual phenomenon.

Common ground

Spectacular weather events like this are not common in northwest Australia.
