It’s a bit of both, says Met Bureau senior forecaster Chris Kent.
Strong north-westerly winds pushed ahead of a trough in WA, mixed with the very dry conditions since March and April, are stirring up dust as well as fanning fires.
The trough is expected in the south-west of the NT by Wednesday, with some cloud cover and lower temperatures expected.
The fine dust is likely to hang in the air for a couple more days until it settles, perhaps by Thursday, says Mr Kent.
