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 15 April 2014, rainfall was recorded over southeastern Australia, eastern Queensland and from the Top End and Kimberley through to South Australia.
A large cloudband stretching from the northwest through central and southeastern Australia at the start of the week triggered thunderstorms over central and northwestern Australia. As the surface trough associated with the cloudband moved eastwards, showers fell over the southern Northern Territory, with locally heavy falls over western and southern parts of the Territory. Meanwhile, a low pressure system over South Australia and a broad surface trough near the western border of New South Wales brought heavy falls through much of South Australia, and moderate falls extending into western New South Wales and northern Victoria.
Severe tropical cyclone Ita brought extensive shower and thunderstorm activity to the Cape York Peninsula and parts of the northern Queensland coast during the first half of the week. Ita intensified to a category 5 system before making landfall over Cape Flattery as a low end category 4 system at approximately 10 pm AEST on 11 April. Ita rapidly weakened as it moved inland before tracking along the coast and crossing back over water. The system continued to bring rain and thunderstorms during the remainder of the week, with widespread cloud extending from the north tropical coast to southeast Queensland and over the Coral Sea.
Rainfall totals over 400 mm were recorded in the North Tropical Coast district of Queensland, with the highest weekly total at Mt Sophia with 418 mm. Falls between 200 mm and 400 mm were recorded in most areas of the Queensland coast from Cape Melville, north of Cooktown, to north of Mackay. Falls between 100 mm and 200 mm were recorded east of Darwin in the Northern Territory, around and west of Coober Pedy in South Australia, along the east coast of Queensland from around Cape Flattery to Gladstone, as well as smaller areas in northern Sunshine Coast and East Gippsland in Victoria. Totals between 25 mm to 100 mm surrounded areas of higher falls and were also recorded in the Kimberley district of Western Australia, western Northern Territory, central and eastern South Australia, most of Victoria, southern and central western New South Wales, much of the east coast of Queensland, and areas of southern, western and northeastern Tasmania.
Most of Western Australia an area extending south from the Gulf of Carpentaria through the eastern Northern Territory, western Queensland, northern New South Wales and the northeast of South Australia received little or no rainfall.
The maps below show the percentage of mean rainfall that has been received for the rainfall deficit period for the 18-month and 24-month periods ending 15 April 2014. Only the areas that experienced serious or severe rainfall deficiencies for the corresponding period ending 31 March 2014 are analysed, the rest of the map is masked in grey shading.
|Rainfall to date for 18-month period||Rainfall to date for 24-month period|
Rainfall deficiencies for the period commencing October 2012 have eased slightly in the southeast of the Northern Territory, western New South Wales and Victoria compared to last week. Affected areas of inland Queensland and adjacent northern New South Wales largely missed out on rainfall this week and deficiencies there and in northeastern South Australia remain similar. Serious deficiencies also remain in an area on the coast of Western Australia near Shark Bay.
Large parts of the area spanning northeastern South Australia, the southeast of the Northern Territory and inland northern Queensland, as well as smaller areas of eastern Queensland and northeastern New South Wales west of the Great Dividing Range and an area on the coast of Western Australia near Shark Bay have received less than 60% of the average rainfall for similar periods ending 15 April.
Rainfall deficiencies for the period commencing October 2012 have generally eased across the southeast of the Northern Territory, South Australia, western New South Wales and Victoria compared to last week. Deficiencies in inland Queensland and adjacent northern New South Wales and on the coast of Western Australia near Shark Bay remain similar to last week.
Most of the Northeast Pastoral District of South Australia and adjacent parts of Queensland, the southeast of the Northern Territory and scattered smaller areas of inland northern and southern Queensland and northern New South Wales have received less than 60% of the average rainfall for similar periods ending 15 April, as has and an area on the coast of Western Australia near Shark Bay.
