A powerful cyclone carrying winds of up to 263km/h (163 mph) has reached the coast of Queensland, Australia.
More than 25,000 people were urged to evacuate ahead of Cyclone Debbie.
The category four storm has already left at least 23,000 homes without power and caused damage on the popular Whitsunday Islands.
The slow-moving cyclone, expected to be Queensland’s most damaging since 2011, is likely to remain over the state for hours, authorities warned.
The storm made landfall between Bowen and Airlie Beach, Queensland Police said.
“We are in for a long, tough day,” said Queensland Premier Annastacia Palaszczuk.
“The intensity and ferocity of the winds is going to be gradually increasing. Everyone is bunkered down.”
Electricity providers said more homes would lose power.
“We’re getting reports of roofs starting to lift, even in some of our own facilities in the Whitsundays,” said Queensland Police Deputy Commissioner Steve Gollschewski.
One person in the region compared the winds to “freight trains coming through left and right”.
“The trees are going wild. The place is just shaking continuously,” the man, identified only as Charlie, told the Australian Broadcasting Corp.
Forecasters had twice delayed predictions of when the cyclone would make landfall.
Ms Palaszczuk described the storm as “a monster” and compared it to Cyclone Yasi, which had devastated towns and flooded evacuation centres.
She said Monday’s emergency evacuation order was “probably the largest ever” for the north-eastern state.
* Forecasters said the tidal surge would now be less than 2m (6ft), and no longer coincide with high tide
* However, authorities warned there would still be flooding in low-lying areas
* The region is expected to be hit with 150-500mm of rain on Tuesday
* Police warned people to beware of fallen powerlines, which could be deadly
* Emergency stockpiles of food and fuel have been set aside, and the army is on standby
Ms Palaszczuk said that shelters had been made available on higher ground for those with nowhere else to go.
More than 2,000 emergency workers are also on standby, but people have been warned crews will only respond when it is safe to do so.
Some residents refused to leave despite warnings that Cyclone Debbie’s destructive core could be as wide as 62 miles (100km).
All flights have been cancelled at Townsville Airport and Mackay Airport.
Police Commissioner Ian Stewart said the weather contributed to the death of a woman in a car crash on Monday.
