Rainfall over the past week was recorded across the western half of Australia and the southeast.

At the beginning of the week, a surface trough extending through the Northern Territory and inland Queensland triggered thunderstorms and showers across the northwest of the Northern Territory.

A deep surface trough extended through central Western Australia to a low pressure system in southwest South Australia and tracked eastward over following days, generating moderate rainfall totals in parts of the west and south of Western Australia. The heaviest falls were recorded along the south coast.

By mid-week, the low pressure system and associated surface trough tracked into the southeast, bringing moderate falls to the southwest and parts of the North West and North East Pastoral districts of South Australia and most of Victoria except the west, with some areas of heavy falls along the Great Dividing Range. Moderate rainfall was also recorded in southeastern New South Wales throughout the Snowy Mountains and South West Slopes.

At the end of the week, a cold front crossed southern Victoria and Tasmania, bringing light falls to Tasmania’s west coast and to parts of eastern Victoria and southeastern New South Wales. A surface trough along the west coast of Western Australia produced a cloudband with embedded thunderstorms, bringing moderate falls to the Gascoyne, Pilbara and Kimberley districts in Western Australia.

Rainfall totals in excess of 50 mm were reported in isolated areas on the south coast of Western Australia. Isolated locations in the northwest of the Northern Territory, the Kimberley district, western Tasmania and along the Great Divide and Snowy Mountains in Victoria and New South Wales also reported rainfall totals over 50 mm. The highest weekly total was 109 mm at Rawlinna Depot in Western Australia.

Rainfall totals between 15 mm and 50 mm were recorded in the Kimberley, Gascoyne and Pilbara districts and surrounding higher falls in southern Western Australia, isolated parts of the northwest Northern Territory and small parts of southwest and eastern Southern Australia. Weekly totals exceeded 25 mm in central and eastern Victoria, part of southeastern New South Wales and western Tasmania.

Rainfall totals above 10 mm were also recorded in southern, western and northern Western Australia, the northwest and small areas between the south of the Northern Territory and eastern South Australia, and surrounding higher falls in Victoria and the southeastern quarter of New South Wales.

Queensland and adjacent parts of surrounding States and the Northern Territory, western New South Wales, eastern Tasmania, parts of the east and west of Western Australia and northwest South Australia recorded little or no rainfall for the week.
