The ground is dry, the air is dry, and the fuel (trees/grass/undergrowth) is all-too combustible.
About the only good news thus far is that it is burning in some rather remote areas - one of the reasons it has grown so large is that the Fire Depts. have concentrated their resources around certain inhabited spots. If there's no loss of life or property those people living up there will be the lucky ones, as there'll be nothing left to burn when the bushfire season reaches it's height early next year...and it gets really hot.
I went out at midnight last night and it was still hot and very hazy, quite surreal. The fires are several hundred km away from where I live, but even here yesterday the day had quite a baleful look, much like in that first pic. The street lights turned on early, and the air was hot and dry enough to rip yer skin off.
We're almost always in drought, but it has been getting steadily worse over the past few years.
This is just the little "bottom right" corner of the country. I'm afraid you'll be seeing too many of these fires on your news over the next few months.
We are subject to water restrictions now. No outdoor watering of gardens, lawns at all for the foreseeable future.
Whew! It is only just past 11AM here, and 36°C already...
Speaking of which, have a look at one of the hottest places on Earth:
At 11AM in Ireland its normally around 5°C at this time of year. I'd rather be cold than as hot as it is by you. How can you go around doing everyday things in that kinda temperature? Like, school and work and stuff like that must suck even harder in that heat...
