Weekly rainfall wrap: Week ending 17 May 2016

Sheep Central, May 18, 2016



It was a largely dry week across Australia.

At the beginning of the week, a surface trough across northern Australia produced onshore showers and thunderstorms, generating moderate rainfall totals in the eastern Top End of the Northern Territory. A deep low pressure system south of Tasmania and an associated low pressure trough tracked across southeastern Australia, generating moderate falls in the western parts of Tasmania and southern parts of Victoria.

Another cold front embedded in a vigorous westerly airstream rapidly crossed Bass Strait, bringing moderate to heavy falls to western Tasmania and elevated parts of the Victorian Alps. A series of cold fronts tracked across Tasmania during the remainder of the week, generating further moderate falls across western Tasmania.

At the end of the week, a cold front moved through southwest Western Australia, bringing light to moderate falls to western and southern parts of the South West Land Division. As the front tracked eastwards, light falls were recorded in southeast South Australia and southwestern Victoria. A moist onshore flow brought persistent shower activity to the northeast coast of Queensland in the second part of the week.

Rainfall totals in excess of 100 mm were recorded in the Victorian Alps and the western half of Tasmania. Falls in excess of 200 mm were recorded on the west coast and highland regions in Tasmania, including the highest weekly total of 378 mm at Mount Read.

Rainfall totals between 50 mm and 100 mm were recorded in the far eastern parts of the Cape York Peninsula, eastern parts of Arnhem Land in the Northern Territory, the Victorian Alps and the Snowy Mountains, and much of western Tasmania.

Rainfall totals between 10 mm and 50 mm were recorded in the northeastern Top End including parts of Arnhem Land, the northeast coast of Queensland, southeastern New South Wales, northeastern and southern Victoria, southwest Western Australia, and in most of Tasmania except along the central east coast.

Most of Western Australia, much of the Northern Territory away from the northeastern Top End, remaining parts of Queensland, New South Wales away from the southeast, most of South Australia and northwestern Victoria recorded little or no rainfall this week.
