Cold fronts and troughs brought moderate falls to the western and southern mainland, as well as Tasmania, and onshore flow produced moderate falls along the country’s far north.
Past seven days: At the start of the week, a surface trough produced showers and thunderstorms in southeast and central Western Australia. Moist easterly winds also brought showers and thunderstorms along the coastal Top End and Gulf Country in the Northern Territory, and the far northern tip of Cape York Peninsula. A low pressure system south of Western Australia extended a cold front northwards, with moderate falls recorded over southwest Western Australia. In the east, a moist onshore flow produced showers along the north tropical coast of Queensland, and showers in parts of northeastern New South Wales.
By the middle of the week, the low pressure system south of Western Australia tracked east into the Great Australia Bight, with the associated cold front and pre-frontal trough crossing Tasmania. Moderate falls were recorded in western Tasmania and light falls were reported in southern central Victoria.
From mid-week, an upper-level disturbance combined with the surface trough and produced a cloudband along the west coast of Western Australia, triggering thunderstorms that produced moderate falls in the southern Gascoyne District. The cloudband later moved south and east, expanding to produce moderate falls over southern Western Australia and southwestern South Australia.
Showers continued to stream onto York Peninsula, the north tropical coast in Queensland and the eastern Top End of the Northern Territory in the last part of the week. A southeasterly onshore flow over the east coast of Australia also brought low cloud and light showers to coastal Victoria, Tasmania and New South Wales.
Rainfall totals in excess of 100 mm were recorded in the far north tropical coast of Queensland, including the highest weekly total of 152 mm at Allingham Forrest Drive.
Rainfall totals in excess of 50 mm were recorded in the far northern Cape York Peninsula and north tropical coast of Queensland, and a small area in western Tasmania.
Rainfall totals between 10 mm and 50 mm were recorded in the Gascoyne, South West Land Division and southern coastal parts of Western Australia; the coastal parts of the Top End in the Northern Territory; the Cape York Peninsula, north tropical, central and southeast coasts of Queensland; the northeast coast of New South Wales; parts of far southern Victoria; most of Tasmania, and southwestern South Australia.
