Storms in WA to generate more dust than rain

Brett Dutschke, Wednesday October 1, 2014 - 13:51 AEST

Thunderstorms will develop across southern parts of Western Australia during the next few days but for many places will bring little rain, just whip up some dust.

Cloud is slowly building into thunderstorms over southwest WA but the atmosphere is looking too dry to bring much rain, with many areas likely to see little more than dust.

For anywhere northeast of a line from about Perth to Albany, windows and cars are more of a chance to end up dirty than get washed.

Any thunderstorms which develop have potential to generate quite gusty winds, strong enough to whip up plenty of dust, particularly given most of them will bring little rain. A jetstream flying above a low pressure trough gives storms the ability to produce gusts strong enough to bring down tree branches.

In general, rainfall in any storm will dump less than five millimetres, although some in the far southwest could bring more than 15mm.

The trough will slowly travel east across the state between now and the weekend, taking showers and storms with it.
