Flooding continues after wet week in northern QLD

Ben Domensino, 5 March 2018

Days of heavy rain have caused flooding across a large swathe of northern Queensland and the wet weather isn't over just yet.

A slow-moving low pressure system located near Cloncurry on Monday morning was producing a swirling mass of thick cloud over northwest Queensland.

This is the same low that inundated the Townsville region with more than 500mm of rain late last week. Since then, it has travelled inland and dumped close to 400mm in parts of the state's northwestern interior during the last three days.

A rain gauge at Carsland to the north of Cloncurry registered 391mm during the 72 hours ending at 9am today.

A number of places in the state's northern outback received more than 100mm of rain during the 24 hours to 9am today. Winton's 102mm was its heaviest fall in 18 years and close to double its entire March average. Julia Creek's 127mm included 108mm in just 6 hours this morning.

The moisture associated with this low also helped fuel thunderstorms across central and southeast Queensland on the weekend. Parts of Brisbane were struck by severe storms on Sunday night and a rain gauge near Lake Samsonvale, to the northwest of the city, collected 102mm during the 24 hours to 9am on Monday.

The low is expected to move towards the northwest and weaken during the coming days, allowing rain to ease slightly as it spreads into the NT. Any further heavy rain in saturated catchments of northwest Queensland is likely to cause further flooding.

As the low moves north it will travel close, or even over, the southern Gulf of Carpentaria during the middle of this week. The Bureau of Meteorology have given the system a low chance (5-20 percent chance) of developing into a tropical cyclone as this happens.
