TROUGHS extending across the eastern seaboard and through western Queensland to northern New South Wales brought rain to large areas of eastern and northern Australia early in the past week.

In the middle of the week a pre-frontal trough extending across South Australia and Victoria moved east through NSW and southern Queensland, bringing light to moderate rainfall.

Towards the end of the week, a trough across northern Australia and down through both the western and eastern sides of the continent, triggered thunderstorms and showers across large parts of northern and eastern Australia.

Past seven days: For the week to 7 December 2021, rainfall was recorded in large areas of the eastern and northern Australia. Areas in the North West Pastoral District in South Australia and central Western Australia also recorded rainfall.

At the start of the week, troughs extended across the eastern seaboard and through western Queensland to northern New South Wales. These combined with an upper level trough and onshore flow, producing thunderstorms and showers in eastern and southern Queensland and northern New South Wales.

Multiples stations observed record-high December daily rainfall totals.

Rainfall eased and contracted to coastal south-east Queensland and north-eastern New South Wales as the trough moved away from the east coast.

Thunderstorms and showers were reported in the Top End in the Northern Territory and in western Cape York and the Gulf country in Queensland.

Light to moderate rainfall was recorded in Victoria and Tasmania, and the south of New South Wales, and moderate rainfall in Queensland’s coastal south-east and north-east New South Wales. Thunderstorms produced light to moderate rainfall in the North West Pastoral district in South Australia.
