Dust-laden skies the colour of pumpkin are not a frequently-occurring phenomenon here. Still, when my husband was urging me to go outside and have a look, my reaction was "Eugh, no thanks."
The sky returned to its usual blue after a few hours, and then there was a lot of sweeping-up of rust-coloured gritty dust to be done. I'd rather clean up after a dust storm than a bushfire, though.
