Weekly rainfall wrap + rain outlook, 8 May 2019

Bureau of Meteorology, May 8, 2019

A COLD front and an associated complex low pressure system produced moderate falls over parts of southern Australia and New South Wales, while a surface trough, extending from the Top End to south-eastern Queensland produced thunderstorms and moderate falls.

Past seven days: At the start of the week, a cold front and an associated cloud band with embedded thunderstorms extended from the north-west to south-east of the continent and brought light to moderate falls to the southern coasts of Western Australia and South Australia. A low pressure trough extended from the complex low pressure system in the southern ocean, and deepened over the bight as the cold front generated isolated thunderstorms with light to moderate falls affecting southern parts of South Australia.

As the cold front and associated large cloud band progressed eastwards, embedded thunderstorms produced widespread moderate falls over parts of western, southern and central New South Wales, south-west Queensland, northern Tasmania and much of Victoria. The cold front continued to track north-east through New South Wales and produced moderate falls over much of north-eastern New South Wales and southern to south-east Queensland during the middle of the week.

Around mid-week, thunderstorms developed along a surface trough extending from the north-west Top End in the Northern Territory to southern Queensland.

At the end of the week, a cold front tracked across southwest Western Australia, and brought rain and moderate falls to the south-west.

Rainfall totals in excess of 100 mm were recorded in north-eastern Victoria, including the highest weekly total of 173 mm at Falls Creek (Rocky Valley).

Rainfall totals in excess of 50 mm were recorded in pockets of southern coastal South Australia; north-western Tasmania; elevated areas of Victoria in the north-east and East Gippsland; south-eastern and small parts of western and north-eastern New South Wales; pockets of the north tropical coast of Queensland; and in the far north-west and north-east of the Top End in the Northern Territory.

Rainfall totals between 10 mm and 50 mm were recorded in along the coast of south-west and southern Western Australia and parts of the northern and eastern Kimberley; southern and north-eastern South Australia; most of Tasmania except an area between the Southeast and Central Plateau districts; most of Victoria except along the western border; most of New South Wales away from the south-east and north-east coasts; western, southern and east coast Queensland; and northern and some eastern parts of the Northern Territory.

Little or no rainfall was recorded in remaining parts of Western Australia, western, central, and southern parts of the Northern Territory, north-west South Australia and along the eastern border in agricultural districts, extending into western border regions of Victoria, much of northern Queensland.
