A surface trough with thunderstorms produced moderate falls in the South West Land Division. A series of vigorous cold fronts produced moderate falls in southeastern Australia.

Past seven days: At the start of the week, a deep surface trough and associated thunderstorms produced light to moderate falls in the Gascoyne district, South West Land Division and southern interior of Western Australia. In the southeast, a cold front tracked across Tasmania and Victoria, with moderate falls recorded in western Tasmania and light falls for remaining parts of the State.

Around the middle of the week, a weak cold front tracked across southwest Western Australia, producing a cloudband and moderate falls for parts of the west coast in southwest Western Australia. An upper-level trough produced a cloudband and isolated embedded thunderstorms, with moderate falls recorded over southeast Western Australia and western South Australia.

At the end of the week, interaction between the upper-level trough and cold front generated an extensive cloudband with further embedded thunderstorms over the southeastern parts of the continent. Moderate falls were recorded along the southern coast of South Australia, southern Victoria, and in western and northern Tasmania as well as in elevated areas of northeastern Victoria and the Snowy Mountains in New South Wales.

Isolated showers produced light falls in pockets of northeast and southeast Queensland and parts of northeastern New South Wales.

Rainfall totals exceeding 50 mm were recorded in western Tasmania, the Mount Lofty Ranges in South Australia and in elevated areas of the Victorian Alps. The highest weekly total was 97 mm at Piccadilly in the Mount Lofty Ranges in South Australia.

Rainfall totals between 10 mm and 50 mm were recorded in areas of southern Western Australia including its southern coast; southern coastal areas of South Australia; in Victoria’s southwest, central and northeastern districts; the Snowy Mountains in New South Wales, and in western and northern Tasmania.

Little or no rainfall was recorded in central and northern Western Australia, the agricultural districts in South Australia, the Northern Territory, Queensland, and most of New South Wales except about the Snowy Mountains.
