Wild weather driven by a strong cold front is whipping up huge dust clouds across large parts of NSW, with Sydney in line for a possible dusting on Thursday.

Remote parts of the state's west, such as the town White Cliffs, 1000 kilometres by road north-west of Sydney, were left a glowing red after being cloaked in dirt on Tuesday. Broken Hill was also in the midst of another dust storm on Wednesday afternoon.

The White Cliffs Hotel posted a video of the storm hitting on Tuesday, which has been viewed more than 76,000 times.

Gabrielle Woodhouse, a forecaster at the Bureau of Meteorology, said some parts of the state were "particularly dry and strong winds can easily pick up the dust". Those winds need to be sustained for several days, though, to carry the dirt - much of it topsoil - over the Great Dividing Range.
