Rainfall for the seven days to Tuesday, July 22, was recorded in much of Western Australia, southern South Australia, southwestern and eastern Victoria, southern New South Wales, and Tasmania.
At the start of the week a cold front associated with a low pressure system in the Southern Ocean crossed South Australia and western Victoria producing moderate rainfall and isolated shower activity as it moved across eastern Victoria, Tasmania and eastern New South Wales.
Showers formed along a surface trough located over the Pilbara mid-week, bringing moderate to heavy rainfall to the northwest of Western Australia. An active cold front followed, and crossed the southwest coast of Western Australia bringing showers and thunderstorms for western parts of the South West Land Division.
At the end of the week, another cold front crossed the southwest coast, resulting in light to moderate rainfall for the southwest and southern coast of Western Australia.
Falls in excess of 75 mm were recorded in isolated areas in the Victorian Alps, and northern Tasmania. The highest weekly rainfall total was recorded in Victoria at Falls Creek (Rocky Valley) with 81 mm. Isolated rainfall totals above 50 mm were recorded in parts of northern and southern Tasmania, the Snowy Mountains and Victorian Alps, and the Pilbara district of Western Australia.
Rainfall totals between 15 mm and 50 mm were recorded in the northwest and southwest of Western Australia, southeastern South Australia, southwestern, central and eastern Victoria, between southern and northeastern New South Wales on and inland of the Great Dividing Range, and in most remaining parts of Tasmania.
Rainfall totals over 10 mm were recorded surrounding areas of higher falls in southwestern, central and northwestern parts of Western Australia, coastal southeastern South Australia, southwestern and eastern Victoria, southern and central New South Wales, and in parts of eastern Tasmania.
The Northern Territory, most of Queensland except the southeast and tropical coast, northwest New South Wales, the northern half of South Australia, eastern Western Australia and parts of the west coast recorded little or no rainfall for the week.
