Ex-Tropical Cyclone Kirrily's moisture makes 5500km long cloud band off Australia's east coast

A satellite image has captured a huge cloud system off Australia's east coast, as remnants from an ex-cyclone move away. 

Leftover moisture from ex-Tropical Cyclone Kirrily has been hovering over Australia and the Tasman Sea for nearly two weeks. 

It's since created a cloud band 5500km long, with help from a polar jet stream, according to Weatherzone Australia.

John Law, meteorologist from New Zealand's Te Ratonga Tirorangi/MetService, stressed the cloud band is not expected to bring any severe weather to Aotearoa. 

"Unlike some of the systems that move in from the tropics this is not a tropical cyclone or even an ex-tropical cyclone, as the system that was Kirrily has dissipated over Australia and is no longer a trackable area of low pressure." 

Kirrily was a long-lasting storm, Law said. 

"Some of that tropical moisture dragged down with the system will have been caught up as that band of cloud and swept across the Tasman Sea by the polar jet." 

Kirrily first slammed into north Queensland on January 25, before moving over the Gulf of Carpentaria, then diving south. 

The category 2 cyclone caused heavy rain, wind damage and flooding in several states. It even affected New Zealand at the time too. 

Law said: "The biggest impact we would have felt from this moisture was some rain on the West Coast and it would have added to those higher temperatures we saw earlier this week." 

The next weather system will bring colder temperatures for the country going into the weekend.
