He added that if 5.5 million hectares of the state had burned in 2019-20, those areas were regenerating and would see fires again.
The Bureau of Meteorology outlook for August to October calls for above average rainfall from eastern Queensland to the south coast of New South Wales; parts of Victoria and the Northern Territory are also likely to experience heavy rain.
The agency also warned that saturated soils from recent rainfall, along with comprehensive water systems – including most dams around NSW above 70% capacity – will increase flood risks in a much of eastern Queensland and NSW for the coming months.
Bureau of Meteorology chief executive Dr Andrew Johnson said the landscape was saturated and dams and rivers were full.
He added that it would likely take a few months before the agency would be able to declare a third consecutive La Nina event, and if climatic factors are strong, that would give authorities greater confidence that a wet summer.
Johnson added that the impacts of climate change were already being felt, including more intense rainfall, longer fire seasons and lower rainfall patterns in Western Australia’s south-west and south-eastern corner. from Australia. But he said it was difficult to link individual events, such as the wet weather NSW experienced three weeks ago, to climate change.
“We know that the frequency and intensity of severe weather phenomena are increasing all over the world,” he said. “We are experiencing this in Australia.”
Johnson said it’s typical to experience an average of 22 lows on the east coast each year, seven of which are significant and two of which result in weather events where rainfall exceeds 100 millimeters.
Sydney has already recorded its wettest July on record after 365 millimeters of rain fell in the CBD. The previous wettest July was 1950 with 336 millimeters. The usual average July rainfall for Sydney is 96 millimeters.
