RAINFALL was recorded in southwest Western Australia, western Tasmania, Victoria, eastern NSW and the north tropical east coast of Queensland for the week ended 9am, 26 April.

At the start of the week, a moist onshore airstream generated persistent shower activity in far northeast Queensland.

Moderate falls were recorded along the north tropical Queensland coast. A complex surface trough tracked over South Australia and an associated cloud-band extended across southeast Australia, with light rain falling along the southern coasts of South Australia and western Victoria.

In the middle of the week, the surface trough crossed Victoria and Tasmania ahead of the cold front, generating moderate rainfall totals in western Tasmania and in central and eastern Victoria. As the southern flank of the trough tracked over NSW, thunderstorms and showers produced moderate falls along most of the east coast, and in a small part of East Gippsland.

At the end of the week, a cold front and a developing cloudband tracked across the southwest Western Australia, with moderate rainfall totals recorded in northeastern parts of the South West Land Division. Moist, onshore flow in the country’s east produced showers with moderate totals recorded in northeastern NSW and the far northeast coast of Queensland.

Rainfall totals between 50 mm and 100 mm were recorded in western Tasmania, parts of central Victoria, northeastern NSW and the north tropical coast of Queensland. Isolated totals exceeding 100 mm were recorded in parts of the north tropical coast of Queensland, including the highest weekly total of 173 mm at Tully Sugar Mill in Queensland.

Rainfall totals between 10 mm and 50 mm were recorded in much of the South West Land Division in Western Australia, western Tasmania, central and eastern Victoria, parts of eastern NSW, the north tropical coast of northern Queensland, and parts of southeastern Queensland.

Most of Western Australia away from the southwest, the Northern Territory, most of South Australia away from the coasts, northwestern Victoria, central and western New South Wales, and most of Queensland away from the north tropical coast recorded little or no rainfall this week.
