Oodnadatta in SA's Far North poised for tilt at its own Australian record temperature of 50.7C Residents in some parts of regional SA have been urged to leave their homes due to catastrophic fire danger. AUSTRALIA'S hot weather record is under threat as intense temperatures envelop the Far North of South Australia today and tomorrow. The remote Outback town of Oodnadatta could break its own official national record of 50.7C - set on January 2, 1960 - as a front associated with ex-tropical cyclone Christine sweeps across Central Australia. As the north of the state sizzles, Oodnadatta's temperature reached a top of 46.6C at 1.47pm. In Tarcoola, it reached 47.8C at 2.15pm. Bureau of Meteorology senior forecaster Matt Collopy said Oodnadatta had the third-highest temperature on record of 50.3C on January 3, 1960, while the second-highest temperature was 50.5C at Mardie in Western Australia on February 19, 1998. The soaring heat comes as the CFS responded to more than 80 incidents across the state yesterday and issued catastrophic and extreme fire danger rates across much of South Australia's north. Bureau of Meteorology acting regional director John Nairn said Oodnadatta was forecast to top 49C but the record could be broken in the next 24 hours. Hot couple of days ahead for the folks of Oodnadatta.

Tomorrow, Christine will bring hot, blustery conditions and wind speeds of up to 55km/h in the north of SA. "It is a weakening system fortunately but it will bring a significant belt of winds," Mr Nairn said. We're forecasting a dust storm to come through with that ... and expect to see elevated fire conditions again. The searing heat comes as the CFS is bracing for a potentially disastrous couple of days. Four districts - Flinders Ranges, the Mid-North, North East Pastoral and North West Pastoral - have a catastrophic fire danger rating today. The rating is extreme in the Eastern Eyre Peninsula, Mt Lofty Ranges, Yorke Peninsula, Riverland and Murraylands districts, and severe for the West Coast, Lower Eyre Peninsula, Adelaide metropolitan and Upper South East districts. CFS chief officer Greg Nettleton said firefighters responded to more than 80 incidents across the state yesterday - several of which were sparked by fireworks. "We were able to clear up those jobs fairly quickly which was quite fortunate because if any fires got away from us during the course of the night ... we would have had a significant day chasing those fires," he said. Mr Nettleton urged residents in the state's north to activate their bushfire plans, as the fire risk continued to escalate. "If I was in the area where we had a catastrophic fire danger and the fire dangers were realised, then, I would have left last night," he said. I'd like to point out this is day one of 2014 ... we're still got to get through the whole of January, February and March.

Climate experts will be in the bureau's Adelaide office today and tomorrow to crunch numbers and determine if new records are set. Mr Collopy said the sizzling heat would continue in the state's north until Thursday morning, when a cooler airstream from ex-tropical cyclone Christine brings relief. He said Moomba in the Far North could expect a maximum of 44C on Friday with a forecast top of 34C on Saturday. Further south in the state, temperatures will drop today as a cooler front with rain brings a respite from yesterday's heat.
