Weekly Rainfall Update

For the week to 17 January 2017, rainfall was recorded in Queensland, the Northern Territory, most of the northern half of Western Australia, as well as southern and northern areas of South Australia. Rainfall was also recorded in southern and northeastern Victoria, western and northern Tasmania; also the southeast and northeast of New South Wales.

The week began with a broad area of low pressure located across northern Australia that produced extensive shower and thunderstorm activity over Queensland’s Cape York Peninsula, the Gulf Country, the Top End of the Northern Territory, and the Kimberley district in Western Australia. A weak tropical low situated off the northern Queensland coast along the trough line produced locally heavier falls. Another trough located along the west coast of Western Australia triggered thunderstorms with moderate totals recorded in parts of the central interior, Gascoyne, Pilbara and Kimberley.

In the middle of the week, a cold front tracked across the south of the country, and an extensive band of thunderstorms formed on the trough ahead of this system. Moderate falls were recorded over southern districts of South Australia, parts of southern and northeastern Victoria, and Tasmania.

At the end of the week, a surface trough extending across much of central Australia produced showers and thunderstorm activity.  Moderate to heavy falls were reported in parts of the Kimberley, central Northern Territory, and in a line from the Gulf Country to northeastern New South Wales. Extensive areas of cloud and embedded thunderstorms located near and to the north of the trough, continued to produce moderate to heavy falls over northeastern parts of the Northern Territory and into Queensland’s Gulf Country and the Cape York Peninsula. Thunderstorms also produced moderate falls in southeastern Queensland and northeastern New South Wales.

Rainfall totals between 100 mm and 200 mm were recorded in pockets of the Kimberley and Pilbara in Western Australia; parts of Arnhem Land and central districts in the Northern Territory; the central west, Gulf Country, Cape York Peninsula and north tropical coast in Queensland; and a small area of northeastern New South Wales. Higher rainfall totals, in excess of 200 mm were recorded through isolated parts of Queensland’s central west, Gulf Country and north tropical coast, including the highest weekly rainfall total of 251 mm at Greenhaven on the Barron North Coast in Queensland.

Rainfall totals between 50 mm and 100 mm were recorded across large parts of the Kimberley and Pilbara districts in Western Australia; eastern parts of Arnhem Land and central districts of the Northern Territory; most of the Cape York Peninsula, Gulf Country and central west in Queensland extending into pockets along the State’s east coast and southeast districts. Similar totals were recorded in isolated parts of northeastern New South Wales and an area in western Tasmania.

Rainfall totals between 10 mm and 50 mm were recorded in much of the northern half of Western Australia; in the far north and southern half of South Australia; southern and northeastern Victoria and in northern and western Tasmania. Similar totals were recorded in southeastern and northeastern New South Wales, and most of Queensland except in the far southwest and inland southern border.

Little or no rainfall was recorded in eastern Tasmania, much of the southern parts of the central interior of Western Australia, large areas of the Pastoral districts of South Australia, and parts of the northwest and eastern areas of Victoria. Little or no rainfall was recorded in remaining parts of New South Wales, southern and southwestern Queensland, and in the far south and far north of the Northern Territory.

Impact of recent rainfall on deficits

Due to above average rainfall in recent months over areas which had experienced deficiencies since mid-2015, no large-scale deficiencies are currently present. Rainfall analyses are available for standard periods out to 48 months.
