Entire town evacuated as flooding strikes - as the Bureau of Meteorology is slammed for failing to predict the severity of the rain bomb

Residents in the Far North Queensland town of Wujal Wujal are set to be evacuated this morning as flooding worsens in the wake of Cyclone Jasper.

Up to 400 people trapped in the town 340km north of Cairns will be airlifted by helicopter at 8am local time and taken to drier land in Cooktown.

Rescue efforts had to be abandoned late on Monday night due to bad weather.

Nine residents, including a seven-year-old and several health workers, were rescued after becoming stranded on the roof of the Wujal Wujal health clinic.

'It now appears likely we will need to evacuate the entire town of Wujal Wujal,' Queensland Premier Steven Miles told reporters on Monday.

'This rainfall is next level.'

It comes as the Bureau of Meteorology is slammed for failing to predict the severity of rain that fell over Cairns and other flooded regions.

On Saturday, the Bureau forecasted Cairns would receive falls of 30-130mm.

However, the city was drenched by more than double the forecasted rainfall on Sunday, with a record-breaking 268mm.

Up to 12 locations across far north Queensland received record rainfall totals with some areas receiving a years worth of rain in a single day. 

Mossman South, an hour northwest of Cairns, received 1,935mm of rain in five days while Black Mountain near Cooktown recorded 2,189mm.

Douglas Shire Mayor Michael Kerr said the BOM 'didn't know the lay of the land'. 

'If this is so record-breaking, how did no one know this was going to happen … we need to have forecasts closer to what is going on.'

However, Mr Miles defended the government service saying the major rain event could not have been predicted by the Bureau. 

'They do the best they can,' the Queensland premier told reporters. 

Emergency services have conducted over 370 swift water rescues since the flooding began last week and have received over 1,000 calls for help. 

 At least nine people were forced to climb onto roofs in Bloomfield and Degarra, where an 85-year-old man has been reported missing.

Prime Minister Anthony Albanese said his government would provide 'whatever is necessary' to ensure residents are kept safe. 

'A number of people are isolated and have needed rescuing from their terrible circumstances so our thoughts go to all people in those communities,' he said. 

The Royal Australian Navy, operating out of the HMAS Cairns naval base, are supporting evacuations with the Australian Defence Force deployed to the region.

In welcome news for flood-weary residents, rain eased significantly overnight on Monday with swollen rivers dropping to moderate and minor flood levels. 

Weather conditions are due to weaken as the ex-cyclone moves northward. 

Up to 14,000 people in 40 communities were still without power on Monday.

A severe weather warning remains in place for Port Douglas, Daintree village, Wujal Wujal, Cooktown, and Hope Vale. A flood warning remains in place for Mossman, Murray, Herbert, Tully, Johnstone, and Mulgrave rivers.

Residents have been warned to keep an eye out for crocodiles that have been washed into residential streets in the wake of the cyclone.

Emergency services will focus efforts on delivering food, fresh water and medicine to dozens of isolated communities in far north Queensland.
