Flood Watch Number: 3

Flooding expected from rainfall over south eastern NT from Thursday.

A humid east to northeast airmass will combine with an upper level trough to produce widespread areas of rain and isolated thunderstorms over central Australia.

Most catchments throughout this area are very dry from unseasonally low rainfall.

Heavy rainfall will initially develop over the Georgina River and eastern Barkly from today, then spread westwards across the northern Simpson Desert, MacDonnell Ranges and Finke River during Thursday and Friday. Rain is expected to ease during Saturday before clearing on Sunday.

Widespread event totals from Wednesday to Saturday of 50-100 mm are expected across the northern Simpson Desert, southern Barkly, eastern MacDonnell Ranges and western Georgina River with 25-50 mm over remaining parts of the flood watch area. The heaviest falls are expected over the southern Barkly, Georgina River, northern Simpson Desert and eastern MacDonnell Ranges on Thursday and Friday.

River levels are expected to rise from their seasonal levels and may impact road conditions throughout the area. Some roads may become impassable, isolating some communities for a period of time.

Catchments likely to be affected include:

MacDonnell Ranges
Finke River and Stephenson Creek
Simpson Desert
Georgina River and Eyre Creek
