Arnhem Land in the Northern Territory, northern Queensland, western Tasmania, and the southwest of Western Australia were the focus of heavy rain in the past week.

At the start of the week, a pair of cold fronts swept across the southeast. The systems brought moderate to heavy falls to the western half of Tasmania, and widespread light falls to southern and central Victoria. A surface trough over the Gascoyne, and a cold front tracking across southern Western Australia generated showers and thunderstorms, producing moderate falls over the central districts, and the South West Land Division in Western Australia.

In the middle of the week, an upper trough extended a deep, moist tropical air mass over northern Queensland, generating heavy rainfall and thunderstorms. The system brought moderate falls to areas of the Gulf Country and Cape York Peninsula, with heavy falls recorded on the north tropical coast of Queensland. Moderate falls were also recorded around Arnhem Land in the Northern Territory.

At the end of the week, a vigorous cold front tracked across southeastern Australia. Moderate falls were recorded in southeastern South Australia, southwest and central Victoria, and western Tasmania.

Rainfall totals in excess of 100 mm were recorded in an area of western Tasmania, parts of Cape York Peninsula and the north tropical coast in Queensland. Falls in excess of 300 mm were recorded around the Barron North Coast in Queensland, including the highest weekly total of 366 mm at Babinda Post Office.

Rainfall totals between 50 mm and 100 mm were recorded in parts of Arnhem Land in the Northern Territory, northern Queensland, western Tasmania, and in the southwest of Western Australia.

Rainfall totals between 10 mm and 50 mm were recorded in the South West Land Division and in parts of the Kimberley district of Western Australia, southeastern South Australia, and in southern, central and northeastern Victoria. Similar totals were recorded across most of Tasmania, southeastern New South Wales, and much of northern Queensland and the Gulf Country including Arnhem Land.

Remaining parts of Western Australia, most of the Northern Territory away from the northeast, most of South Australia, eastern and northern Victoria, almost all of New South Wales and the southern half of Queensland recorded little or no rainfall this week.
