The Weekly Rainfall Update provides a detailed analysis of the rainfall recorded across the country during the past week. The page is updated every Tuesday afternoon, for the seven days ending that day. The update includes a rainfall map, a table of the highest falls recorded for the week by state, some commentary and an analysis of the impact of recent rainfall on parts of Australia experiencing rainfall deficits.

State weekly rainfall bulletins (updated daily):
The table above lists the highest rainfall totals for each state and territory for the past week. These are based on real-time rainfall reports, and only limited quality control has been performed on the data. Rainfall district names are given in parentheses. Please also note that some station names have been shortened by taking away words such as post office and airport. Map of the Bureau of Meteorology rainfall districts.
In creating the weekly rainfall map, the rainfall recorded at sites across Australia is analysed onto grids and displayed as a map. In data-rich areas, such as southeast Australia, or in regions with strong rainfall gradients, such as across mountain ranges, 'data smoothing' may occur, resulting in gridpoint values differing from the exact rainfall amounts measured at the contributing stations.
For the week ending 4 March 2014, rain was recorded in the Northern Territory, northern and western Queensland, most of New South Wales, eastern Victoria, western Tasmania, and the far north of Western Australia. At the start of the week, troughs and associated cloudbands over the eastern states produced showers and thunderstorms across western Queensland, much of New South Wales and northeastern Victoria, with some heavy rainfall along the central New South Wales coast, while a monsoon trough across the tropical north with an associated slow-moving low over the Top End produced showers and thunderstorms with moderate to heavy falls for the Kimberley region of Western Australia, the Top End of the Northern Territory, and across the Gulf Country and the Cape York Peninsula in Queensland.. A number of weak cold fronts produced mainly light rainfall over western Tasmania at the start of the week.
Weekly rainfall totals of 50 to 100 mm were recorded across large areas of the tropics, including the Top End of the Northern Territory, the northern Kimberley region of Western Australia and across western Queensland from the Cape York Peninsula extending into central and eastern parts of New South Wales. Weekly totals in excess of 200 mm were reported at some locations in the Top End of the Northern Territory, with Ngukurr Airport receiving the highest weekly total of 250 mm. Rainfall totals of 10 to 50 mm surrounded areas of higher falls and also extended into southern parts of the Northern Territory, Queensland’s tropical north, coastal New South Wales, northeast Victoria and southwest Tasmania. Most of Western Australia, South Australia and southeast Queensland recorded little of no rainfall throughout the week.
The Drought Statement, to be issued this week, discusses rainfall deficits over Australia for the 17-month and 23-month periods ending 28 February 2014. The rainfall deficit maps are available for 17-month, 23-month periods as well as for standard periods.
The maps below show the percentage of mean rainfall that has been received for the rainfall deficit period for the 17-month and 23-month periods ending 4 March 2014. Only the areas that experienced serious or severe rainfall deficiencies for the corresponding period ending 28 February 2014 are analysed, the rest of the map is masked in grey shading.
|Rainfall to date for 17-month period||Rainfall to date for 23-month period|
Rainfall deficiencies for the period commencing October 2012 have eased across western Queensland and adjacent parts of the Northern Territory following rainfall during February and early March, lifting large parts of this area out of serious deficiencies (i.e. rainfall for the period now exceeds the lowest 10% of records). However, serious to severe deficiencies remain in much of eastern Queensland and northeastern New South Wales west of the Great Dividing Range. Serious deficiencies also remain in smaller areas of western Queensland and adjacent parts of the Northern Territory, South Australia and New South Wales as well as in eastern New South Wales, western Victoria and on the coast of Western Australia near Shark Bay. Much of southwestern and southern Queensland and adjacent parts of New South Wales, northern South Australia and an area covering northwestern Victoria and the New South Wales Riverina have received less than 70% of the average rainfall for a 23-month period ending February.
Rainfall deficiencies have also eased in western Queensland for the 23-month period commencing April 2012, with less pronounced easing across the east of the Northern Territory and South Australia and along the eastern border of South Australia. Rainfall for the period for much of western Queensland and parts of the Northern Territory, northern South Australia and along the border between South Australia and Victoria and New South Wales, has risen above the lowest 10% of records. Serious to severe deficiencies remain in areas of western and inland northern Queensland, eastern South Australia, extending across the border, and in an area extending from inland southern Queensland through much of New South Wales inland of the coastal ranges and into northwestern and north-central Victoria. Deficiencies also persist in an area between Geraldton and Shark Bay on the west coast of Western Australia. Much of southern Queensland, inland northern New South Wales, northern South Australia and an area covering northwestern Victoria and the New South Wales Riverina have received less than 70% of the average rainfall for a 23-month period ending February.

Drought declarations are the responsibility of the State Governments, and take account of other factors in addition to recent rainfall patterns.
