Huge dust storm sweeps Queensland,Australia

A colossal dust storm rolled through communities in north-west Queensland
yesterday as wind speeds reached up to 109 kilometres per hour.

The storm swept through the communities of Mount Isa, Boulia, Dajarra and
Urandangi.

"It's the biggest one I've seen in eight years," said long-time Boulia
resident Leaim Shaw.

Meteorologist at the Bureau of Meteorology Helen Kirkup attributed the dust to
a line of several thunderstorms in the region.

"What happened yesterday is we had a long line of storms stretching across
about 100 kilometres. Any thunderstorm puts out a cold air outflow.

"Because we had a line of storms we had a gust front of all these cold air
outflows working together. So residents would have experienced the dust storm,
and then thunderstorms following that," she said.
