Horrifying footage has emerged of Cyclone Debbie from the International Space Station.
The category four cyclone is the worst to hit Queensland since Yasi 6 years ago.
Residents are urged to evacuate and to prepare for the intense cyclone about to hit.
This cyclone moves around a heck of a lot ... we're now well within the firing line. If you can possibly get to higher ground you should do that right now
Urges Mackay Regional Mayor Greg Williamson.

Storms are categorised by the strength of their winds, although the wind itself often isn't the most deadly part of the tempest. Storm surges—pulses of water pushed by the advancing cyclone—often result in coastal flooding.
