Weekly Rainfall Update

Weekly Rainfall Update
for 7 days to 9 am 28 October 2014

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.

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.

Commentary on recent rainfall

For the week ending 28 October 2014, rainfall was recorded in the far north and southwest of Western Australia, southeast South Australia, Victoria, Tasmania, parts of eastern Queensland, and across northern and eastern New South Wales.

At the start of the week, a low pressure system was located over southwest Western Australia with an associated surface trough extending into the Kimberley region in Western Australia which produced moderate rainfall in the South West Land Division. A surface trough over western New South Wales associated with
another low pressure system centred over western Victoria triggered isolated thunderstorms through inland and eastern New South Wales.

A weak cold front crossed Tasmania during the middle of the week, bringing light to moderate rainfall to most of Tasmania. A lingering surface trough over Bass Strait and a broad trough of low pressure across southern and western New South Wales resulted in moderate totals through northern Tasmania and in parts of southern Victoria, and light rainfall through much of Victoria and parts of southeast South Australia. A deepening area of low pressure along the northwest coast of Western Australia brought isolated falls to parts of the Kimberley

At the end of the week, a cold front 
crossed Victoria and Tasmania with an associated surface trough extending northward and connecting with the monsoon trough in northern Australia. Thunderstorms were triggered across parts of eastern Australia, resulting in moderate rainfall totals to western Tasmania and eastern Victoria with some light rainfall also recorded in southeastern Queensland.

Rainfall totals over 50 mm were reported in western and northeastern Tasmania. The highest weekly total was 62 mm at Mount Read in Tasmania.

Rainfall totals between 25 mm and 50 mm were recorded through much of northern and western Tasmania, in a small area of southwest Western Australia and in West Gippsland in Victoria.

Rainfall totals between 15 mm and 25 mm were recorded in 
the Kimberley and in areas surrounding higher falls in southwest Western Australia, most remaining parts of Tasmania, and through West and East Gippsland in Victoria.

Rainfall totals between 10 mm and 15 mm were recorded surrounding higher falls in southwest and northern Western Australia, eastern Victoria, isolated parts of eastern and western New South Wales, and small areas of southeast Queensland.

The Northern Territory, most of Western Australia except for the southwest and far north, South Australia, inland New South Wales and 
Queensland, away from the coast, recorded little or no rainfall during the week.

Impact of recent rainfall on deficits

The Drought Statement issued on 6 October 2014, discusses rainfall deficits over Australia for the 10-month (December 2013 to September 2014) and the 24-month (October 2012 to September 2014) period ending 30 September 2014. The rainfall deficit maps will be available for the 10-month and 24-month period 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 10-month and 24-months ending 28 October 2014. Only the areas that experienced serious or severe rainfall deficiencies for the corresponding period ending 30 September 2014 are analysed, the rest of the map is masked in grey shading.

Rainfall for the period 1 December 2013 to 28 October 2014

Serious to severe deficiencies (lowest 10% to 5% of records) are in place across a large area of northeastern New South Wales and southeastern Queensland, western Victoria, eastern Tasmania and small areas of the southern coast of Western Australia.

Compared to last week, there has been a slight increase in deficiencies in parts of southeast Queensland, northeastern New South Wales and in western Victoria. Some easing of deficiencies is evident across Tasmania. Much of these areas have recorded less that 70% of their average rainfall for the period.

Rainfall for the period 1 October 2012 to 28 October 2014

Serious to severe deficiencies (lowest 10% to 5% of records) remain in a large area of inland Queensland away from the eastern coast and in smaller areas in adjacent parts of the Northern Territory, South Australia and northern New South Wales inland of the Great Dividing Range. Much of these areas have received less than 70% of average rainfall for the period. Deficiencies are also evident in much of inland western Victoria, extending across the border into part of southeastern South Australia, and in an area of the southern coastal Gascoyne around Shark Bay in Western Australia.

Compared to last week, deficiencies increased slightly in areas of inland Queensland, and in western Victoria.

Please Note: The Australian Bureau of Meteorology is not responsible for drought declarations. Drought declarations are the responsibility of the State Governments, and take account of other factors in addition to recent rainfall patterns.
