Weekly Rainfall Update

For the week to 18 October 2016, rainfall was recorded in the northwestern Top End, the east coast of Queensland, eastern to central New South Wales, Victoria, Tasmania, southern parts of South Australia and southwest Western Australia.

At the start of the week, a cold front embedded in a westerly airstream tracked across Tasmania and Victoria. Moderate falls were recorded in western Tasmania, and light falls were reported across much of Victoria and southeastern New South Wales.

From the middle of the week, a number of weak cold fronts tracked across southwest Western Australia, while a cloudband associated with a pre-frontal trough developed and extended from the northwest of the continent to western Tasmania. Moderate falls were recorded in southwest Western Australia, along the southern coastline of South Australia, and in southwestern Tasmania. As this cloudband continued to track across South Australia, Victoria and Tasmania, another cloudband associated with the next cold front tracked from the eastern Bight and across the southeast at the end of the week. Between them, the cloudbands generated moderate falls across large parts of southeastern Australia at the end of the period.  

A band of thunderstorms moved across southern Queensland and eastern New South Wales at the end of the week, associated with the first of the two cloudbands, generating moderate falls in southeast Queensland and northeastern New South Wales.

During the week, a moist onshore flow onto the east coast of Queensland and northern New South Wales produced moderate falls about the north tropical coast of Queensland and the mid-north coast of New South Wales.

A few showers and storms brought rainfall around Darwin in the Top End at the start of the week, and light falls across a larger area of the Top End at the end of the week.

Rainfall totals between 50 mm and 100 mm were recorded in western Tasmania, pockets of the Snowy Mountains and Victorian Alps, the Mount Lofty Ranges in South Australia, and pockets of the north tropical coast of Queensland. The highest weekly total was 121 mm at Mount Read in Tasmania.

Rainfall totals between 10 mm and 50 mm were recorded in southwest Western Australia, in southeastern South Australia and about the Yorke and Eyre Peninsulas, across most of Victoria except the Mallee and central north, and all of Tasmania apart from the northeast coast. Similar totals were recorded from central New South Wales to the centre of the Great Dividing Range and across northeastern New South Wales, along much of east coast of Queensland south of Cooktown, and in the Darwin–Daly region in the Top End of the Northern Territory.

Little or no rainfall was recorded in Western Australia except the southwest and southern coasts, most of the Northern Territory away from the Top End, northern, western and central Queensland, central and western New South Wales and the northeast coast of Tasmania.

Impact of recent rainfall on deficits

Due to above average rainfall in recent months over areas which had experienced deficiencies since mid-2015, no large-scale deficiencies are currently present. Rainfall analyses are available for standard periods out to 48 months.
