08 Jan 2013 - By Jonathan Pearlman



A seven-day record-breaking heatwave has led to a mass outbreak of fires across the country and warnings of “catastrophic” conditions in the most populous state of New South Wales.

In Sydney, temperatures reached 108F (42C), as authorities confirmed that a nationwide average of 104.6F (40.33C) on Monday was the hottest day in recorded history, surpassing a previous mark set in 1972.

The scorching conditions are set to continue into the coming week and prompted the national Bureau of Meteorology to take the extraordinary measure of revamping its weather charts. New colours have been added to forecasting maps — deep purple and pink — to mark out areas experiencing peaks above 122F (50C).

The colours have come in for immediate use, with large purple blotches appearing on the weather map for next Sunday and Monday. Temperatures in parts of the state of South Australia are tipped to exceed 122F (50C).

    • Another small town lost many homes today as fires continue. Lightning and continued hot weather has many towns preparing for evacuation, battling fires and trying to keep other fires already burning contained.

      We have so far been lucky in our own area as lightning started only small blazes that were quickly brought under control. I've got to go to help with other preparations as the weather hots up again.

    • Fires still burn across NSW. Lightning strikes have started new fires overnight unfortunately extending the length of time fire fighters and residents will have to continue battling these outbreaks for.

    • I'm reading people are stating everything was burning and it was like fire tornadoes coming towards them. I also read there was a bit of cooling but that another heatwave is coming. Hold on. How are water resources holding up?

      "We saw tornadoes of fire just coming across towards us and the next thing we knew everything was on fire, everywhere all around us," he said.

      'Tornadoes of fire'
      Tasmania was the first state to be affected, before fires broke out in New South Wales.

      Some blazes have also been reported in Victoria and Queensland.

      Officials said of some 120 fires in New South Wales, 17 remained uncontained, and more than 3,000 sq km (1,160 sq miles) of land has been destroyed.
      The worst blazes are in the state's south near Yass, Sussex Inlet and Cooma.

      At Dean's Gap, near Sussex Inlet, more than 100 firefighters are trying to stop the blaze reaching the disused army range.

      They are using special gels and bulldozers to carve out containment lines.

      "We need to get a really good handle on that fire before high fire danger conditions return," said a Rural Fire Service (RFS) spokeswoman.

      Firefighters have been scrambling to take advantage of cooler weather on Wednesday and Thursday.

      In Cooma, there are at least 80 firefighting aircraft, 360 fire trucks and more than 1,000 RFS volunteers trying to contain the fires in the area, local reports say.

      Bushfires also continue to cause concern in Tasmania.

      A large blaze is still burning out of control by the Tasman peninsula, near areas already hit by major blazes over the weekend.

      More than 200 sq km of land and 120 homes have been destroyed.

      "Even though conditions at the moment have calmed down a little bit, that doesn't mean that people can become complacent," said Tasmania Fire Service's Paul Symington.

      "They still need to be vigilant, still monitor the websites and the radios because if things do change, they need to be on top of it."

      A couple in Tasmania and their five grand-children, pictured here, sought shelter in the water under a jetty as flames closed in on the town of Dunalley
      Photos of a Tasmanian family clinging to a jetty surrounded by fire have been widely shared by the international media.

      Tim Holmes said he and his wife and their five grandchildren sought shelter in the water under a jetty for three hours.

      "We saw tornadoes of fire just coming across towards us and the next thing we knew everything was on fire, everywhere all around us," he said.

      Later on, he managed to make his way to shore and fetch a dinghy to transport his wife and the children."

      Luckily some rain fell in early summer which provided some badly needed water after a pretty dry winter for many areas. NSW has experienced some flooding in recent years, though many rural areas have continued to receive very low and irregular amounts of rainfall.

      It's kind of pot luck depending on where you live. Quite a few areas in NSW were lucky enough to get some decent amounts of rain. A number of towns are piping or tanking in water regularly from other areas or planning to as their usual water supplies have decreased in recent years. Even towns that once had very high rainfall like my own are now looking at major water piping projects to ensure adequate water supplies after decades of decreasing rainfall.

      Some of the fires in Tasmania were fought by local volunteers using pumps to pump up water from the nearby ocean bay into 250L tanks on the back of utility vehicles. In many remote rural areas this is often the option that has been used for some decades when the nearest town with proper fire-fighting equipment is a long way away.

      We've often used green branches off trees with a good number of leaves on them to whack out the flames of grass fires, even brush fires when they are not too hot to get near. Until the last couple of decades green branches, wet hessian sacks and shovels were the main means of fire control in many isolated communities. We've even dragged the plough on the back of the tractor through the fire front to turn up the ground in an emergency. Many of our old water pumps were too big to even move so small modern pumps have been a real blessing for fighting small to moderate fires.

      Fire tornadoes doesn't sound good, that's usually a sign of some nasty fire creating it's own wind.

      It has cooled off here and and a few other areas for the time being at least. I think parts of NSW have had some easing conditions, but large parts of the north east and inland NSW were getting extreme and severe fire danger warnings last night so it's a pretty hairy situation. With more hot weather forecast this week it's going to be a while before people can relax a bit.
