For today’s 14-day rainfall outlook – scroll to bottom of article

A SERIES of cold fronts and low pressure systems tracked across south west Western Australia, generating moderate falls. Cold fronts also produced moderate falls in south eastern Australia.

Past seven days: At the start of the week, a cold front extended over the Tasman Sea with a complex low pressure system to its west. Showers and thunderstorms produced light to moderate falls in Tasmania, most of Victoria, south eastern New South Wales and south eastern South Australia. A surface trough also produced thunder storms and moderate falls in southeastern Queensland. In the west, a deep low pressure system and associated cold fronts approached the south west of Western Australia, producing an extensive cloud band, with moderate falls reported in the South West Land Division in Western Australia.

From the middle of the week, a cold front emanating from the same low pressure system tracked across south west Western Australia, generating a westerly flow and mainly light falls. Another vigorous cold front and associated cloud band followed, producing further light to moderate falls in the south west corner of Western Australia. The cold front continued its eastward track, weakening as it reached the southeast. Widespread light falls were recorded in western Tasmania, most of Victoria and south eastern South Australia.

Rainfall totals in excess of 100 mm were recorded in an area of south west Western Australia, including the highest weekly total of 129 mm at Worsley Downs.

Rainfall totals between 50 mm and 100 mm were recorded across most of the Lower West and Central West districts in southwest Western Australia, the western half of Tasmania, and in small pockets of the Snowy Mountains in New South Wales and the Victorian Alps.

Rainfall totals between 10 mm and 50 mm were recorded in remaining areas of the South West Land Division in Western Australia; about the Mount Lofty Ranges, Mid North and South East districts of South Australia; in southwest, central and north eastern Victoria, as well as parts of East Gippsland; most of Tasmania except the northeast, and in south eastern Queensland.

Little or no rainfall was recorded in the Northern Territory, most of Queensland except the southeast corner, New South Wales away from the Snowy Mountains area, all of South Australia except in the southeast and remaining parts of Western Australia away from the south west.
