Sydney was painted red...

Yesterday, I was woken to a surreal red glow in the sky just outside the window. At the same time, I was able to hear and see a severe wind was lashing and whipping up a bright orange haze across the field. Before I realised what actually happened, a blanket of red dust had begun to shroud Sydney just before dawn after a cold front moved in from central Australia and western NSW and causing severe delays at Sydney airport and prompting warnings from health authorities. By mid morning, everything was painted red inside and out side the house with a fine film of reddish colour of ochre powder. I have no idea how the red dust crept into the house with every window and door tightly shut.
