Okay, um, I think the person writing the headline might have got a bit carried away here. From the article:
"A lot of the dust will be blown across the Tasman Sea and most will end up in the sea.
"There could be traces of dust in rainfall but I would be surprised if it will be noticeable."
Today’s sunset may have “a bit more of a red tinge to it”.
Yep…apocalyptic is definitely the word for that.
