Weekly Rainfall Update
for 7 days to 9 am 22 July 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 22 July 2014, rainfall was recorded in much of Western Australia, southern South Australia, southwestern and eastern Victoria, southern New South Wales, and Tasmania.

At the
start of the week a cold front associated with a low pressure system in the Southern Ocean crossed South Australia and western Victoria producing moderate rainfall and isolated shower activity as it moved across eastern Victoria, Tasmania and eastern New South Wales.

Showers formed along a surface trough located over the Pilbara mid-week, bringing moderate to heavy rainfall to the northwest of Western Australia. An active cold front followed, and crossed the southwest coast of Western Australia bringing showers and thunderstorms for western parts of the South West Land Division.

At the end of the week, another cold front crossed the southwest coast, resulting in light to moderate rainfall for the southwest and southern coast of Western Australia.

Falls in excess of 75 mm were recorded in isolated areas in the Victorian Alps,  and northern Tasmania. The highest weekly rainfall total was recorded in Victoria at Falls Creek (Rocky Valley) with 81 mm. Isolated rainfall totals above 50 mm were recorded in parts of northern and southern Tasmania, the Snowy Mountains and Victorian Alps, and the Pilbara district of Western Australia.

Rainfall totals between 15 mm and 50 mm were recorded in the northwest and southwest of Western Australia, southeastern South Australia, southwestern, central and eastern Victoria, between southern and northeastern New South Wales on and inland of the Great Dividing Range, and in most remaining parts of Tasmania.

Rainfall totals over 10 mm were recorded surrounding areas of higher falls in southwestern, central and northwestern parts of Western Australia, coastal southeastern South Australia, southwestern and eastern Victoria, southern and central New South Wales, and in parts of eastern Tasmania.

The Northern Territory, most of Queensland except the southeast and tropical coast, northwest New South Wales, the northern half of South Australia, eastern Western Australia and parts of the west coast recorded little or no rainfall for the week.

Impact of recent rainfall on deficits

The Drought Statement issued on 22 July, discusses rainfall deficits over Australia for the 7-month (December 2013 to June 2014) and the 21-month (October 2012 to June 2014) period ending 30 June 2014. The rainfall deficit maps are available for the 7-month and 21-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 7-month and 21-months ending 22 July 2014. Only the areas that experienced serious or severe rainfall deficiencies for the corresponding period ending 30 June 2014 are analysed, the rest of the map is masked in grey shading.

Rainfall for the period December 2013 to 22 July 2014

For the 7-month period commencing December 2013, serious to severe rainfall deficiencies remain in place over southeastern Queensland, northeastern New South Wales, along the southern coast of Western Australia and parts of southeastern Tasmania. Deficiencies in most areas remain largely unchanged compared to last week. Deficiencies increased slightly in southern parts of Queensland, with some relief in northeastern New South Wales.

Most of the coastal parts of northeastern New South Wales and smaller areas of eastern Queensland have received less than 50% of their average rainfall for similar periods ending 22 July 2014.

Rainfall for the period October 2012 to 22 July 2014

For the 21-month period commencing October 2012, serious to severe deficiencies (lowest 10% to 5% of records) remain in an area spanning much of Queensland away from the eastern coast and an area of northern New South Wales inland of the Great Dividing Range. Rainfall during the last week brought some easing of deficiencies over southern inland Queensland and central northern New South Wales, while deficiencies remained largely unchanged elsewhere.

Areas of northeastern South Australia, the southeast of the Northern Territory, inland northern Queensland, and southeastern Queensland and northeastern New South Wales west of the Great Dividing Range have received less than 60% of the average rainfall for similar periods ending 22 July 2014.

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