A blistering heat wave is headed eastward in Australia, prompting authorities to warn of extreme fire danger in the southeastern state of Victoria.
State fire authorities are calling for temperatures as high as 44 degrees C (111 degrees F), together with gusty winds, on Friday, the Australian ABC News website said on Wednesday. This would be the first "extreme fire day" of the summer fire season, they also said.
There were more than 60 grass and bush fires in Victoria on New Year's Day, which was not exceptionally hot.
Wednesday, the heart of the hottest air spanned a vast swath of desert and scrub in Western Australia and South Australia, far to the west of Victoria.
Highs of 45.9 degrees C (115 degrees F) were set in southeastern Western Australia, both at Forrest and at Red Rocks Point. Highs were as many as 20 degrees C (36 degrees F) above normal along the Great Australian Bight.

The mass of the exceptional heat wave is forecast to shift eastward, baking not only Melbourne, the commercial hub of Victoria, but also Adelaide in neighboring South Australia state.
Friday's forecast high temperatures, according to AccuWeather.com, are 105 degrees F (40.5 C) in Melbourne, and 102 degrees F (39 degrees C) in Adelaide.
Victoria has tracts of forest and bush, as well as grass and cropland, any of which can be prone to burn during the summer fire season.
Victoria residents are well of the dangers of wild fire in their state. The tragic Black Saturday blazes of Feb. 7, 2009, left 173 Victorians dead and another 414 injured -- Australia's highest ever loss of life -- according to Wikipedia.
The plum rains are known as "meiyu" in China, the "baiyu" or "tsuyu" in Japan, and the "jangma" in the Koreas. The heart of the plum rain season stretches from early June to mid-July, with a tendency to shift south to north across the affected area.
In the wake of the mid-June cloudbursts, most of Pakistan to northwestern India last week saw a return to dry, hot weather typical of the weeks leading up to the Monsoon onset. It was as if the Monsoon withdrew to its "normal" position for the latter half of June.
The 38.5 degree C (101 degrees F) reading Tuesday in Ajaccio, Corsica, may have been tops in Europe.
Monsoon Onset was June 13th, 2013, in Delhi, almost two weeks earlier than average. The June 15th onset at Karachi and Islamabad was more like three week ahead of schedule.
In Pakistan, hit-or-miss downpours missed the Sindh capital, Karachi. One did hit Pad Idan, where it left 60 mm of rain Wednesday. This was more than 20 times greater than the normal June rainfall.
It is still possible that this scenario is over wrought as to the intensity and spread of rain in Pakistan and northwestern India. However, it is the hunch of the present forecaster that some very unusual weather is going to unfold in the Subcontinent during the next week!
