Weekly rainfall wrap + rain outlook, 11 March 2020

Bureau of Meteorology, March 11, 2020

Lows brought moderate to heavy falls across New South Wales, Victoria and Tasmania.

Past seven days: In the first part of week, ex-tropical cyclone Esther moved east-southeast across the Northern Territory, southwest Queensland and northern New South Wales.

A deepening surface trough extended from the Northern Territory, through the remnants of Esther, inland eastern mainland and south through Tasmania. An embedded low pressure system developed in central Victoria. Moderate to heavy rainfall was recorded in central to southeastern parts of the Northern Territory, in western and southwestern Queensland, and parts of western New South Wales. Moderate falls were also recorded in far northeastern South Australia.

The slow-moving surface trough and embedded lows interacted with an upper-level disturbance, producing further widespread moderate to locally heavy falls across most of Queensland, New South Wales, Victoria and Tasmania until the middle of the week. A surface trough across northern Western Australia also brought moderate falls to parts of the Pilbara, and isolated showers in central and southern parts of that State.

Around the middle of the week, onshore flow produced showers along most the east coast of Queensland and New South Wales, while showers and thunderstorms developed over the northeast Top End.

In the last part of the week, a surface trough was located from northwest to southern Queensland, into western New South Wales. Showers and thunderstorms developed east of the trough, with moderate falls over much of northern, central and southern Queensland, as well as along that State’s east coast. Another trough extended across northern Australia and monsoonal flow developed to the north of Australia. Moderate falls were also recorded in the northern Top End of the Northern Territory.

Rainfall totals in excess of 200 mm were recorded in parts of the central coast of Queensland, including the highest weekly total of 428 mm at Samuel Hill Aero.

Rainfall totals in excess of 100 mm were recorded in the northern Top End of the Northern Territory; parts of the Cape York Peninsula, central and Capricornia coasts, and southwest Queensland; far northeastern South Australia; pockets of central New South Wales; elevated areas of northeastern Victoria, and parts of northern Tasmania.

Rainfall totals in excess of 50 mm were recorded in the northern Top End and central to southeastern parts of the Northern Territory; western, southern inland, northern, and along the east coast of Queensland; across northern, central, southern and southeastern parts of New South Wales; central to northeastern Victoria, and much of northern Tasmania.

Rainfall totals between 10 mm and 50 mm were recorded in parts of the Pilbara coast of Western Australia, most of northern and eastern parts of the Northern Territory, most of Queensland, New South Wales, Victoria, Tasmania, and far eastern parts of South Australia.

Little to no rainfall was recorded in most of Western Australia, far southern parts of the Northern Territory, and South Australia away from that State’s far east.
