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 11 March 2014, rain was recorded in the tropical north, along the eastern seaboard and in areas of central Australia and the southeastern mainland. At the start of the week, a tropical low over the northeast of the Top End moved to the eastern Gulf of Carpentaria while a second low over the Solomon Sea slowly tracked southwest towards the western Coral Sea. The low in the Gulf of Carpentaria intensified to a category 1 tropical cyclone by mid-week while the second low veered southeast off the east coast of Queensland. Tropical cyclone Gillian weakened to a low as the system moved south along the west coast of Queensland and the second low became tropical cyclone Hadi as it moved northeast away from Queensland’s east coast. Showers and thunderstorms were reported in the tropical north during the week, as well as the tropical east coast of Queensland during the latter part of the week. A broad trough triggered isolated showers and thunderstorms with light to moderate rainfall over the interior and coastal southeastern mainland before a trough and a weak cold front moved through the southern mainland producing cloudy conditions and isolated thunderstorms with mainly light rainfall over the southern coast and northern Tasmania.
Weekly rainfall totals of 50 to 100 mm were recorded in the Top End of the Northern Territory, the Kimberley region of Western Australia and the Cape York Peninsula, and east coast of Queensland. Weekly totals in excess of 200 mm were reported at some locations, with Cape Wessel (an offshore location) in the eastern Top End in Northern Territory receiving the highest weekly total of 295 mm and Lockhart River Airport in the Cape York Peninsula in Queensland receiving the second highest total of 212 mm. Rainfall totals of 10 to 50 mm surrounded areas of higher falls and also extended into southern and eastern parts of the Northern Territory, Queensland’s southeast coast, western and coastal New South Wales and adjacent parts of Victoria and South Australia. Most of Western Australia, South Australia and western Victoria and central Queensland recorded little of no rainfall throughout the week.
The Drought Statement, issued on 5 March, 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 11 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 remain similar to last week, with serious to severe deficiencies in much of central and 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 17-month period ending February.
Rainfall deficiencies remain serious to severe 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.
