Broad low pressure troughs produced moderate falls through Western Australia and northern and eastern Australia, while heavy falls were recorded in the north tropical Queensland coast after ex-tropical cyclone Owen crossed near Port Douglas.
Past seven days: At the start of the week, showers and thunderstorms brought moderate falls to eastern Queensland and northern Australia due to broad surface troughs in these regions. A cold front and associated cloudband brushed the far southwest of Western Australia, with moderate falls recorded in the area. As the cloudband tracked eastwards, light falls were reported along parts of the southern coasts of Western Australia and South Australia.
A surface trough extending from the Gulf Country to Queensland’s southern interior produced further showers and thunderstorms, with moderate falls in the Cape York Peninsula, northern interior, and north tropical to central coasts of Queensland. Isolated thunderstorms developed about the Top End in the Northern Territory, the Kimberley and parts of inland Western Australia to around the middle of the week.
In the second half of the week, broad surface troughs extended across the north and west, and from the northwest to southeast of Australia. Isolated thunderstorms and showers developed along and near the troughs, with moderate falls recorded in the Top End of the Northern Territory, the Kimberley, and through inland Western Australia. The deepening trough in central Western Australia produced thunderstorms and moderate falls from the Goldfields to southeast Western Australia. Moderate falls were also recorded in northern and northeastern Victoria and southeast New South Wales.
In the last part of the week, ex-tropical cyclone Owen was embedded on a deep trough off the north coast of Queensland and tracked slowly west southwest. Ex-tropical cyclone Owencrossed around Port Douglas in the north tropical coast early on 10 December, and produced heavy rainfall along the north tropical coast and adjacent inland districts. The tropical low then tracked over the Cape York Peninsula, bringing further heavy falls to parts of the north tropical coast and western areas of the Cape York Peninsula, and moderate falls to remaining parts of far north Queensland.
The highest weekly total was 632 mm at Cardwell Marine Parade in the north tropical Queensland coast. Rainfall totals exceeding 200 mm were recorded around the north tropical Queensland coast, while falls in excess of 100 mm were recorded in areas of the Cape York Peninsula, and north tropical and central coasts of Queensland.
Rainfall totals exceeding 50mm were recorded along parts of Queensland’s east coast and remaining parts of the Cape York Peninsula.
Rainfall totals between 10mm and 50mm were in the Kimberley, eastern Pilbara and Goldfields Districts, as well as southwest and southern parts of Western Australia; the Top End of the Northern Territory; small areas along the southern coast of South Australia; northern and northeast Victoria; southeastern and parts of the east coast of New South Wales; and eastern and northern Queensland.
Little or no rainfall was recorded in remaining parts of Western Australia; the southern two-thirds of the Northern Territory; western, central and southern Queensland; remaining parts of New South Wales; most of South Australia; northwest and southwest Victoria and most of Tasmania.
