Australia braced for new round of bushfires

Australian firefighters are on high alert for the possibility that scorching temperatures and strong winds could whip up new bushfires on Thursday, after rain brought welcome respite to fire-ravaged areas.



Unprecedented bushfires fuelled by climate change have killed at least 29 people and devastated vast swathes of the country since September.



Those blazes have been followed by extreme weather – including intense storms that have battered parts of Australia with giant hail, floods and landslides – that has hampered clean-up operations in some areas.



Heavy rainfall has helped to contain and, in some cases, extinguish long-running blazes but an expected return to searing heat and gusting winds Thursday was flagged as a cause for concern as dozens of fires continued to burn.



Temperatures will tip above 40 degrees Celsius in parts of the country – including in Australia's biggest city, Sydney – while wind gusts of up to 90 kilometres per hour are forecast in some areas.



New South Wales Rural Fire Service commissioner Shane Fitzsimmons said firefighters were on "heightened levels of alert", with bans on lighting fires in place across much of the state amid predictions of "severe" fire danger.



"There's every potential for flare-ups and new ignitions to come out of some of these fire grounds, remembering we've got thousands of kilometres of fire perimeter," he told reporters.



"A lot of it has been extinguished, a lot of it is under control – but there are still pockets that are burning and smouldering and we don't know how many additional roots, tree stumps or branches are likely to flare up under those conditions." (AFP)
