bushfire

Widespread October bushfires in NSW are unusual, but have happened before, such as in 1991. This year there was an Early start to Australian bushfires, record temperatures in early September.

It is now the 7th time this bushfire season a total fire ban has been declared in Sydney. Very Unusual. If the fire weather is this bad so early in the season, it can get worse over the coming months as Summer heats up, especially if we have extreme summer heatwaves similar to 2013.

Update: Sunday 20 October: Premier Barrie O'Farrell has declared A State of Emergency across NSW for 30 days as weather conditions are now forecast to be worse than anticipated. Indefinite Total fire bans, and increased powers for emergency personnel. The State Mine fire in the Blue Mountains has burnt 38,000 hectares and is burning on a broad front from Lithgow to west of Bilpin.

On Monday the Prime Minister of Australia Julia Gillard visited the bushfire devastated town of Dunalley in Tasmania and expressed her support for the residents of the town, many of whom lost everything, and outlined emergency assistance measures being taken by both the Federal and Tasmanian Government.

She also said, very briefly, that bushfires were part of Australian life in a hot and dry country. But then she went a step further. She acknowledged that climate change contributes to the frequency and intensity of bushfires through more extreme weather events like the current extreme Heatwave.

Jan 4: Hobart recorded it's highest recorded minimum temperature Thursday night and highest recorded daytime temperature on Friday. Bushfires are currently raging in Tasmania destroying houses and forcing evacuations (see below).

Jan 3: Elevated temperatures in an extreme heatwave are occuring across a brought sweep of Australia, with the heatwave expected to last at least a week. It is very unusual that a heat wave covers such a large area of the continent at one time, according to Karl Braganza, manager of climate monitoring at the Australian Bureau of Meteorology. Australia's weather has switched to hot and dry after one of the wettest two year periods in Australia's history influenced by an extremely strong La Nina event.

Grass fires and bushfires are starting already, and it is only early October - with bushfire season officially still nearly a month away. The extremely wet season Australia had at the end of 2010 and start of 2011, brought on by one of the strongest La Niña on record, has stimulated vegetation growth and is set to cause great concern as it dries and cures in the summer heat with the onset of the summer bushfire season.
