Hobs, I can tell you from first hand experience that you will be in for an education, maybe not this year, or next year, but it will happen again.
I was born in Windyalla, spent a third of my life there, used to own a Des's cab, and my mother ran the kitchen at the Eyre Hotel, so I do have some knowledge of the place. Only 6 to 8 inches of rain per year, but beware when it all comes within 20 minutes on one day.
When I was 9, I witnessed the first instance of this weather phenomenon, then again at 14 years of age, and again at 18 years old.
The summer day starts as usual, hot but not muggy... its a dry heat coming from the North West and the temperature climbs steadily through the day. Around midday, there is a strange red line on the horizon to the north and west, which gets taller, and taller, with black clouds above it.
Dust storm!... when it hits, extreme wind gusts... TV antennas get blown off roofs, Trampolines have to be recovered from neighbours yards, chookhouses and their contents disappear from Stuart, and can be found in Norrie, or Playford.... and the rain is right on top of it, and it rains RED MUD for a half hour.
I was working at the Blast Furnace the last instance that this occurred, when the dust storm hit, the wind was so strong that it blew an 18 wheeler sideways off the wharf near where the slag heaps from the blast furnace are located.
