A Day In Hell
Melbourne has already recorded its hottest-ever February day, with the temperature in the city reaching 46 degrees Celsius at 2:27pm (AEDT).
The mercury reached 47.4 degrees at Avalon between Melbourne and Geelong at 2:41pm, while 46.8 degrees was recorded at Laverton.
In regional areas, it reached 46 degrees at Mildura, 46 at Yarrawonga and 45.3 at Aireys Inlet.
Embers are falling on townships which are being threatened by a fierce bushfire which is burning out of control and threatening power lines east of Melbourne .
Fires are raging across Victoria, South Australia and New South Wales, with tens of thousands of fire fighters on stand-by across all three states.
The fire in Bunyip State Park is now within a kilometre of major transmission lines that feed power to the Victorian capital.
"We're expecting the temperatures to get into the mid-40s today and this afternoon, and we're expecting the wind speeds to increase, so as that happens, the speed of this fire will increase."
The Victorian Ambulance Service is evacuating people from aged care homes at Neerim and Bunyip.
