Weekly rainfall update + rain outlook 10 November 2021

Sheep Central November 10, 2021

LOW pressure systems brought moderate falls of rain to the eastern two-thirds of the continent over the past week, and moderate to light falls to the southern and inland parts of Western Australia.

Early in the week a surface trough produced rain activity and thunderstorms across the northern regions.

Around mid-week, a deep low in the west moved quickly south-east across southern Victoria, and north-east Tasmania, and a broad area of low pressure extended into the Northern Territory and across north-west to south-east Queensland.

At the end of the week, surface troughs stretched across the north, producing further extensive thunderstorms and showers.

Past seven days: For the week to 2 November 2021, rainfall was recorded in southern and the eastern parts of Western Australia, the Northern Territory, north-western and south-eastern South Australia, the southern half and the alpine regions of Victoria and Tasmania. Rainfall was also recorded in north-eastern New South Wales, and in western, central and southern Queensland.

At the start of the week, a trough and a low pressure system crossed southern Western Australia, and brought light to moderate falls to the south-west of that state. A cold front and pre-frontal trough moved through South Australia and the far south-east of Australia, and produced light falls over southern Western Australia, and parts of the agricultural districts of South Australia, with moderate falls in the coastal areas. A surface trough extended from the Kimberley, across the Top End to south-east Queensland. Thunderstorms developed near the surface trough over the Kimberley, the north-west Top End in the Northern Territory, and in spots from north-west to south-east Queensland.

The low in the west moved to South Australia and deepened over south-east South Australia early on the 28th, with the associated frontal system extending south over Tasmania. Moderate to locally heavy falls were recorded in far south-east South Australia, south-west Victoria, including more than 50 mm at both Coleraine and Portland and Tasmania, including 59.6 mm at Cape Grim, a new October daily rainfall record for that site.

Around mid-week, the deep low moved quickly south-east across southern Victoria, and north-east Tasmania, and moved into the Tasman Sea, with the associated cold front moving through parts of eastern Australia.

In the north, a broad area of low pressure extended into the Northern Territory and across north-west to south-east Queensland, with the associated cloudband linking to the cold front tracking across the south-east of that state, and north-east New South Wales. Thunderstorms and showers produced moderate falls in the Kimberley, the central NT and the Top End, western and southern Queensland, and north-east New South Wales.

At the end of the week, surface troughs stretched across the north, and from the Gulf Country through the central west to south-east Queensland. Extensive thunderstorms and showers brought widespread moderate falls to the Kimberley and Interior districts in Western Australia, most of the Northern Territory, and in the Gulf Country, north tropical coast, and central west of Queensland.

Rainfall totals in excess of 50 mm were recorded in parts of the Kimberley in Western Australia, spots in the Northern Territory and western Queensland, south-west Victoria and most of Tasmania except the north-east. The highest rainfall for the week was 97 mm at Mount Read in western Tasmania, and at Point Stuart in Top End of the Northern Territory.

Rainfall totals of 10 mm to 50 mm were recorded in south-west, northern and the Southern Interior District of Western Australia, most of the Northern Territory, north-western and southern South Australia, the southern half and the alpine regions of Victoria, Tasmania, north-eastern New South Wales, and northern, western and southern Queensland.
