Weekly rainfall update + rain outlook 26 Jan 2022

Bureau of Meteorology, 26/01/2022

 

A low pressure system over South Australia with an associated trough extending north brought widespread moderate falls over South Australia, particularly around the Eyre Peninsula, southern parts of the Northern Territory, and the Kimberley, while a monsoon trough across far northern Australia produced widespread showers and thunderstorms, with moderate falls across most of the northern tropics.

Past seven days: At the start of the week, surface troughs extended down the west coast, across the north and down through eastern Australia, with a low pressure system located over south-west Queensland. Widespread moderate falls were recorded in the Gascoyne and Kimberley in Western Australia, eastern and southern parts of the Northern Territory, western and southern Queensland, and northern and eastern New South Wales.

In the middle of the week, a low pressure system was located over inland South Australia, with an associated trough extending north. Widespread moderate falls were recorded over South Australia, particularly around the Eyre Peninsula, southern parts of the Northern Territory, and the Kimberley. Moderate to locally heavy falls were also recorded in the north tropical coast of Queensland.

A monsoon trough was located across far northern Australia, and extended to a tropical low off the Kimberley coast in Western Australia, and produced widespread showers and thunderstorms, with moderate falls across most of the northern tropics.

In the last part of the week, the low and trough over South Australia was near-stationary, while another trough extended across inland western Queensland, western New South Wales, and Victoria. The systems continued to bring moderate falls to the eastern half of South Australia. As the second trough moved further eastwards, moderate falls were recorded in north-east South Australia, western Queensland, northern and eastern parts of the Northern Territory, and across the far northern tropics.

Rainfall totals in excess of 200 mm were recorded in the Eastern Eyre Peninsula District in South Australia, isolated spots in the Manning District in New South Wales, the Darwin – Daly District in the Northern Territory, and isolated parts of the north tropical coast of Queensland, including the highest weekly total of 265 mm at Mount Sophia.

Rainfall totals in excess of 100 mm were recorded across parts of the Kimberley, parts of the north-west coastal Top End in the Northern Territory, pockets of the south-west and north tropical coast of Queensland, and areas of the north-east and southern South Australia.

Rainfall totals between 50 mm and 100 mm were recorded in the Kimberley, the north and east of the Northern Territory, western Queensland and spots in the state’s northern tropics and south-east, north-west and north-east New South Wales, and much of the eastern half of South Australia.

Rainfall totals of 10 mm to 50 mm were recorded in remaining areas of the Kimberley and in the Gascoyne in Western Australia, most remaining areas of the Northern Territory, most of Queensland except an area of the central coast, and most of northern and eastern New South Wales.
