An orange haze has spilled over the Blue Mountains and is descending on Sydney.

The dust storm, whipped-up by strong winds in the state’s far west, is being pushed towards the coast by a low-pressure system.

Satellite images show the 500-kilometre long line of dust, stretching from the Victorian border, through Canberra and up to Queensland.

Health authorities are warning the storm will reduce air quality and has urged children, older people and those with respiratory conditions to take extra care.

“Dust may aggravate existing heart and lung conditions and cause symptoms like eye irritation and cough,” says Environmental Health Director Richard Broome.

While the red sky is reminiscent of a 2009 storm that hit Sydney, the Bureau of Meteorology predicts today’s events won’t be nearly as bad.
