Today’s 14-day rainfall outlook – scroll to bottom of article

A wet week for the western half of the continent with rainfall totals between 100mm plus were recorded in the Top End, Darwin-Daly and Arnhem Land areas of the Northern Territory and the Kimberley, Pilbara, South Central and South West Land Division in Western Australia.

Past seven days: The monsoon trough extended across northern Australia, with associated cloud and rainfall. Showers and thunderstorms affected northern Australia throughout the week. Heavy falls were reported on the north tropical coast of Queensland, the Gulf Country, the Northern Territory Top End and the Kimberley in Western Australia.

At the start of the week, a tropical low embedded on the monsoon trough, located west of Broome in Western Australia, produced moderate to locally heavy falls from the Pilbara, across the Gascoyne and Goldfields districts, to the south coast of Western Australia. As the tropical low tracked slowly southwest, and deepened, heavy falls occurred about the Pilbara coast, with further moderate falls across much of southern Western Australia.

The tropical low, located on the Gascoyne coast by the middle of the week, continued its southwesterly track. Middle level cloud streamed from the tropical low, with thunderstorms and showers producing moderate falls along the west coast and in the southwest of Western Australia. Locally heavy falls were reported around Perth, with daily falls in excess of 100 mm.

In the east, a low pressure trough extended from central Australia into central eastern New South Wales, and directed an east to southeasterly onshore airstream onto the southeast coast. Flash flooding occurred in and around the Sydney area.

In the last part of the week, the tropical low tracked off the Gascoyne coast, and the associated trough extended into the central and northern interior of Western Australia. Further heavy falls occurred in parts of the southwest and southern coasts, Gascoyne and central interior of Western Australia. Flooding occurred in several river catchments, including the Avon and Swan.

At the end of the week, a cold, southwesterly air stream produced moderate falls in western Tasmania, while light falls were recorded in central southern and eastern Victoria.

Rainfall totals between 100 mm and 200 mm were recorded in the Illawarra coast in New South Wales; parts of the Cape York Peninsula and north tropical coast of Queensland; Gulf Country; Top End of the Northern Territory, and the Kimberley, Pilbara coast, and southern parts of the South West Land Division in Western Australia. Totals in excess of 200 mm were recorded in parts of South Central, Pilbara and Kimberley coasts in Western Australia, the Darwin–Daly district and areas of Arnhem Land in the Northern Territory. The highest weekly rainfall total was 325 mm at Dum In Mirrie Airstrip in the Northern Territory.

Rainfall totals between 50 mm and 100 mm were recorded in remaining parts of the Kimberley, areas of the western Pilbara, Gascoyne, Goldfields and South West Land Division in Western Australia; much of the northern half of the Northern Territory; the Cape York Peninsula extending south to the north tropical coast and northern interior of Queensland; parts of the Illawarra and south coast of New South Wales, and in parts of western Tasmania.

Rainfall totals between 10 mm and 50 mm were recorded in most of the western half and central interior of Western Australia; across the central parts of the Northern Territory; remaining parts of the Cape York Peninsula, northern interior, and pockets of east coast Queensland. Similar totals were recorded along much of the east coast of New South Wales; central southern and far eastern Victoria, and the western half of Tasmania.

Little or no rainfall was recorded in southeastern and the northern interior of Western Australia, the southern half of the Northern Territory, much of southern Queensland away from the east coast, central and western New South Wales, central and western Victoria, eastern Tasmania and South Australia.
