Bush fires,Changing weather may lead to loss of control
Bush fires in Australia are threatening to get out of control again because of strengthening winds and rising temperatures. The fires have been burning close for up to six days to Australia's largest city, Sydney.
Over the past two days, calm weather has helped firefighters contain some of the 100 fires across the state of New South Wales. However, temperatures are expected to reach up to 40 degrees tomorrow, accompanied by strong winds.
Electrical storms are also forecast, and lightning could start even more fires.
