Rainfall received across Australia for the seven days to yesterday.

North western Western Australia and parts of northern Queensland and Cape York Peninsula received the most significant falls across Australia over the past week.

At the beginning of the week, a broad surface trough was located across inland parts of the Pilbara and Kimberley, along with a tropical low off the Pilbara coast. Rain was recorded in Western Australia, with moderate to heavy falls recorded across the Pilbara and Gascoyne, and moderate totals in the Kimberley.

A slow-moving surface trough extended over western Queensland, generating moderate totals across much of the Cape York Peninsula. A strong cold front tracked across Tasmania and produced moderate rainfall totals in western Tasmania, and light falls in parts of southern Victoria and the southeast coast of South Australia.

In the middle of the week, thunderstorms and showers continued to form about the Kimberley and Pilbara coasts of Western Australia due to the lingering low pressure trough extending along the west coast. An active area of storm activity also occurred over central Australia. Moderate to heavy rainfall totals continued to accumulate in much of the Pilbara, Gascoyne and Goldfields in Western Australia, and across the northern Cape York Peninsula. The interior of the Northern Territory recorded moderate rainfall totals north of Alice Springs.

Moist and humid winds continued to feed into a low pressure trough across northern Australia, with moderate to heavy falls recorded in the Kimberley, across the Top End and large parts of the Cape York Peninsula. A surface trough extending from the northwest to southeast interior of Queensland produced moderate rainfall totals through the State’s northern interior.

Late in the week, isolated convective activity about parts of northern Western Australia and in a line stretching from Cape York Peninsula to the southern interior of Queensland brought moderate falls in the western Kimberley, the western Top End, large parts of the Cape York Peninsula extending down through inland and southern Queensland.

A series of cold fronts tracked across Tasmania and southeast Australia during the second half of the week, producing moderate rainfall totals in western Tasmania during the middle of the week followed by light falls in Tasmania, southern and southwest Victoria and moderate falls on Tasmania’s west coast at the end of the week.

Rainfall totals in excess of 100 mm were recorded in parts of the Kimberley, Pilbara and Gascoyne districts of Western Australia, the north of the Cape York Peninsula, and in a small area of western Tasmania. The highest weekly total was 232 mm at Mount Read in Tasmania.

Rainfall totals between 50 mm and 100 mm were recorded across large areas of the Gascoyne, Pilbara  and Kimberley, and parts of the Goldfields districts in Western Australia, much of the Cape York Peninsula and most of western Tasmania.

Rainfall totals between 10 mm and 50 mm were recorded across most of northern Western Australia, the western half of Western Australia north of the Central Wheat Belt, most of the Top End and parts of the interior of the Northern Territory, through the interior of central and southern Queensland, in a small area of southeastern Queensland and northeastern New South Wales, parts of central southern Victoria, and in the west and northeast of Tasmania.

Most of South Australia, Victoria away from the southern coast, southern and inland Western Australia, the south and interior of the Northern Territory, nearly all of New South Wales, large parts of western and south Queensland  recorded little or no rainfall for the week
