Weekly rainfall wrap, week ending 18 Aug 2015

Sheep Central, August 19, 2015

2015-8-19-rainfall-mapThe highest rainfall totals for the week of between 50mm and 100mm were recorded in the west of Tasmania.

Falls between 10mm and 50mm were recorded in parts of the South West Land Division in Western Australia; in areas of the Eyre Peninsula, Kangaroo Island, the Mount Lofty and Flinders Ranges and the lower southeast of South Australia; in parts of southwestern Victoria, South Gippsland, the northeast and East Gippsland; much of southeastern New South Wales west of the Great Dividing Range; the western half and northeast of Tasmania; and pockets of coastal southeastern Queensland.

At the start of the week, a vigorous cold front associated with a complex low pressure system located in the Great Australian Bight moved across South Australia. The system brought moderate rainfall to much of the State’s southern parts, particularly east of Ceduna. Light rainfall continued across western Victoria and parts of southern New South Wales as the systems tracked across southeastern Australia.

A surface trough extended along the eastern sea board and tracked eastward as the front and complex low moved off the coast, producing moderate rainfall totals in parts of southern New South Wales and light to moderate falls in southeastern Queensland. Light rain continued over most of Victoria and southeastern South Australia in a southwesterly airstream.

A cold front crossed the Bight during the middle of the week, delivering light rainfall to coastal South Australia, small pockets of New South Wales and Victoria, and western Tasmania. Light rainfall continued across Victoria with moderate falls in western Tasmania as a pair of cold fronts embedded in a southwesterly airstream crossed southeast Australia during the last part of the week.

Meanwhile, a cold front and deepening low pressure system approaching the west coast brought light to moderate rainfall to southwest Western Australia before it crossed into the Great Australian Bight.

The Northern Territory, most of Queensland, Western Australia away from the southwest, the northern and western half of South Australia, and northern and western New South Wales recorded little or no rainfall.
