Today’s 14-day rainfall outlook – scroll to bottom of article

Rainfall was recorded across all of northern Australia – from the Pilbara and the central interior of Western Australia, in much of the Northern Territory; also in the central west, northern and the central coast of Queensland. Rainfall was also recorded in the southern, central and eastern districts of South Australia; northeastern Victoria; northeastern Tasmania and much of eastern New South Wales.

Past seven days: At the beginning of the week, the monsoon trough extended over the Kimberley, across the Top end of the Northern Territory and across far north Queensland. A tropical low embedded on the trough near the Darwin-Daly district in the Northern Territory produced heavy rain and squally thunderstorms, with broad areas of showers and thunderstorms forming in the vicinity of the monsoon trough. This low moved slowly southwest, bringing further heavy falls for the Kimberley district and the Pilbara district in Western Australia. Meanwhile, shower and thunderstorm activity associated with a surface trough north of Tasmania produced mostly light falls.

In the east, a small tropical low on a coastal trough located off the central Queensland coast produced moderate to locally heavy falls about the State’s central and north tropical coasts, and for parts of northern Queensland. Another surface trough extended from central Australia to eastern parts of South Australia, producing light to moderate falls in the Northeast Pastoral and Flinders districts. Isolated showers developed along the coastlines of southern Queensland and New South Wales due to a moist easterly onshore flow.

During the last part of the week, the tropical low located over the eastern Pilbara slowly tracked to the southwest, producing moderate to heavy falls for the central interior and Pilbara district in Western Australia.

Meanwhile, broad areas of showers and thunderstorms extended across the Gulf of Carpentaria associated with the tropical low located in the Coral Sea, which continued to feed very moist and unstable conditions over northern Queensland. Further heavy falls occurred on the north tropical and central Queensland coasts to the end of the week.

The highest weekly total was 822 mm at South Johnstone in the north tropical coast of Queensland, though this is not depicted on the rainfall map. Weekly totals exceeding 700 mm were recorded across the north tropical coast, while weekly totals exceeding 400 mm were recorded in the north tropical and central east coasts of Queensland.

Weekly rainfall totals exceeding 200 mm were recorded in parts of the central interior and Kimberley district in Western Australia; Queensland’s northern interior, north tropical coast and adjacent inland districts, and central coast.

Weekly rainfall totals exceeding 100 mm were recorded across much of the Kimberley, parts of the Pilbara and central interior districts in Western Australia; an area of Arnhem Land and the western Northern Territory; the Gulf Country and parts of the Cape York Peninsula, and much of the east coast of Queensland north of St Lawrence; and a small area along northeast coast of New South Wales.

Rainfall totals between 50 mm and 100 mm were recorded in large areas of Western Australia’s central interior, eastern Pilbara and most of the Kimberley; central, northeastern and central western parts of the Northern Territory, and the northern half of Queensland as well as a small area of the southeast coast. Similar totals were recorded in a small area of northeastern New South Wales and elevated parts of northeastern Victoria

Rainfall totals between 10 mm and 50 mm were recorded along Queensland’s east coast and adjacent inland districts south of St Lawrence extending into the State’s central and northwestern districts; surrounding higher falls in the central interior and Pilbara districts in Western Australia, and pockets of the Top End, the southwest, central and southeastern Northern Territory. Similar totals were recorded along the southwest coast, central eastern and the Northeast Pastoral district in South Australia; as well as northeastern Victoria and a small area in northeastern Tasmania.

Little or no rainfall was recorded in the southeast, north and northwest of Tasmania; much of southern and southwestern Victoria; the far southeast, northwest and northeast of South Australia; along the west coast and the southern third of Western Australia; southern Northern Territory; southwest and southern Queensland, and central and western New South Wales.
