Weekly rainfall update + rain outlook 22 February 2023

Bureau of Meteorology, February 22, 2023

TROPICAL low activity in the Gulf of Carpentaria brought heavy rainfall during the week to surrounding areas of Cape York Peninsula, the Queensland Gulf Country and central and eastern regions of the Northern Territory.

The heaviest falls, with weekly rainfall totals of 200 to 300 mm, were recorded in the lower Cape York Peninsula and along the Queensland tropical coast from Cairns to Innisfail.

Areas of the Queensland Gulf Country, northern Cape York Peninsula and parts of the Northern Territory recorded weekly totals of 100 to 200 mm, and most of the rest of northern Australia recorded 25 to 100 mm.

Storms along the New South Wales coast, notably around Sydney, and into southern Queensland resulted in widespread weekly totals of 25 to 50 mm, with higher totals locally.

The highest weekly total at a Bureau gauge was 358 mm at Tung Oil Alert (near Innisfail, Queensland), including the highest daily total of 202 mm on 17 February.

Moderate flooding continues on several Queensland rivers, but in New South Wales flood warnings have been finalised for the Lachlan River.

Summer 2022-23 rainfall for north-eastern New South Wales and south-eastern Queensland has so far been very much below average (in the driest 10% of all summers since 1900).
