Temperatures in the Far North communities of SA plummeted from the high 40s down to 17C on Sunday as Ex-Cyclone Yasi circled the top end of the state.
Pastoral areas north of Coober Pedy sustained heavy flooding leaving many Stations inaccessible except by helicopter according to Trevor Wright of Wright’s Air, based at William Creek.
Ernabella on APY Lands had the highest rainfalls at 201.6 mm (8 inches), Arckaringa Station 167 mm, Todmorden Station 178 mm and Hamilton Station 138 mm. (Thurs overnight - Monday morning)
“A big flood is occuring in the Alberga River and still rising”, said Douglas Lillecrapp of Todmorden Station on Monday. ”It is the highest since March 1989, but still has to rise another 300 mm to reach the 1989 peak”.
By Monday morning other locations measured in at: *Mount Barry 130 mm, *Nilpinna Station 115 mm, Arkaroola 122.3 mm, Marree 111.8 mm, Marla 142.2 mm, Mintabie 114.9 mm, *Macumba Station 106 mm, *Mt Dare 102 mm, Oodnadatta 100.6 mm, Yunta 138.6 mm, Andamooka 73 mm, Leigh Creek 54.4 mm, Billakalina Station 77 mm, Millers Creek 80 mm. (*Subject to update).
Mintabie’s Post Mistress Kay Marshall said, ” The first big lot of rain came through on Sunday after the remnants of Cylone Yasi changed direction. We estimated the average wind speed at 40mph (about 64 kph) due to the nature of our wind generator, which changes tone at 40 mph and starts “screaming”. This went on during bursts of high winds all through Sunday night when another round of heavy rain fell on the town. Like Coober Pedy, our temperature dropped dramatically to 17C on Sunday.”
Mrs Marshall commended the Bureau of Meteorology for their accuracy in pinpointing the areas where heavy flooding would occur in the Northern Pastoral areas.
Coober Pedy totalled 73.8 mm by Monday with wind speeds measuring up to 72 km/ph with more rain predicted as Yasi changed course and moved across into Western Australia.
Yoka Dunstan of John & Yoka’s Opal and Art in Coober Pedy said, “We are glad the rain has stopped for now! Any more and we could be in trouble”.
”Nothing like the poor people in Queensland that had the flood and had their entire life washed away. You can see how close the water came to our front door (photo at top) and since Sunday has flowed down on the shop verandah even more. Lucky Coober Pedy doesn’t get this very often”. said Mrs. Dunstan.
Martin Smith, Manager at Radeka Downunder in Coober Pedy said, “It was interesting watching people take photos of the temperature gauge here at Radekas reading 45C degrees one day and 17C the next”.
Ex-tropical cyclone Yasi driven by a strong La Nina event crossed over the Queensland border into the Northern Territory on Friday.
The swirling mass of airborne moisture passed over Tennant Creek, did a left hook, taking in Alice Springs and reaching down into South Australia where Far Northern towns and Stations were to expect up to 8 inches of rain in some areas
The core of the ex-tropical cyclone Yasi was estimated at over 500km wide and including its range of activity, spanned in access of 2000km, easily reaching across into two states.
The category 5 cyclone made a catastrophic entrance into Australia via the North Queensland coast last Thursday 3 February at 1am.
Since Thursday, the tour de Yasi across inland Australia wreaked severe storms, gale force winds, floods and unusually cold temperatures in its wake.
In Coober Pedy, Mine Rescue/SES volunteers bagged thousands of sandbags over the weekend as flood waters began rising in parts of the town while the slow moving Yasi continued it’s turbulent journey.
Residents and businesses in Coober Pedy started sandbagging their properties as heavy cloud from ex-tropical cyclone Yasi circled overhead on Saturday morning.
George Russell owner of Oasis Tourist Park and Bulls Garage like many other residents of Coober Pedy in the Far North stacked sandbags around his business premises anticipating severe storms over the next few days as predicted by the BOM.
Coober Pedy is situated on the Oolgelima Creek which takes most of the storm runoff from the town. The creek is a tributary to Lake Cadibarrawirracanna.
Pastoral stations north of Coober Pedy have been the hardest hit with heavy flooding on Saturday night and Sunday. Most outback roads were already closed by 5pm Saturday night due to only minor flooding at that stage.
Helen Williams of Nilpinna Station (115 mm) said, “The rain is very welcome after the long stretch of hot weather we’ve all had. It will be nice to see the dams and the rainwater tanks full again and hopefully it’ll boost up the feed for coming season”.
Hamilton Station (138 mm). ”The airstrip is completely under water and is waist deep,” said Samantha Fitzpatrick a Jillaroo at Hamilton Station. “Tomorrow we’re moving the motorbikes and equipment from the workshop up on to higher ground so they won’t be damaged. Having rain straight after the big fire at Hamilton will really help regenerate the vegetation. I imagine the roads will be closed for several weeks, so it’s just as well we are stocked up with supplies, otherwise we’d be in trouble”, said the Hamilton Station Jillaroo.
Patrick Williams Manager of Arckaringa Station (167 mm) said, “the rain is definitely a good start to the year with good summer feed coming out of it”. “We may have to repair a few fences but that’s a small price to pay.”
Douglas Lillecrap reported 178 mm at Todmorden – Monday morning. “I’m hoping this big rain event will drown all these rotten mice”, Douglas said quite seriously.
“Everyone from Alice Springs right down to Port Augusta has been battling with mice for at least three months and with 700,000 ha that’s a lot of mice if you can imagine 1,000 mice per ha. They are simply devouring everything. I’ve even had them in the fax machine and in the printer!” said Douglas.
Adam Plate from Oodnadatta said, “Water flows from the 178 mm falls on Todmorden Station are making their way to Lake Eyre . The road crossing of Neales River, which has no causeway yet, is about 2 metres deep today (Monday)” . “This is possibly the biggest flood since 88-89 and visible from the village of Oodnadatta”, Adam said.
Pink Roadhouse staff Tiny Van Breusegem and Audrey Bernard were fascinated with the rising flood at the junction of Kempe Rd and Oodnadatta Tracks 1.5 km east of Hookeys waterhole on the Neales River and took some time out to enjoy the Yasi spectacle in Outback South Australia.
