Ongoing flooding in eastern Australia is set to get worse as more rain is channeled across already saturated catchments.
Bureau of Meteorology chief hazard preparedness and response Steve Bernasconi says severe thunderstorms and widespread rain are expected on Sunday.

“All of this is contributing to the existing widespread flooding in inland New South Wales,” he said.
Conditions are expected to ease around Tuesday with cooler, drier and calmer conditions.
The NSW SES has set up a flood rescue center in Goulburn and is positioning staff and vehicles in areas of concern including Albury, Young, Yass, Wagga Wagga and other towns along the Murray River system.
Residents in parts of South Albury were told to evacuate on Sunday morning.
The SES has 89 alerts, including 12 emergency evacuation alerts.
Commissioner Carlene York urged people to heed the SES’s warnings and evacuation orders.
“Some people still aren’t listening, but unfortunately they’re making their decisions based on what they’ve seen in the past.”
“But we’ve seen time and time again that the water is rising further than it may have been for many years, and that’s because of land saturation,” York said.
The volunteer workforce has been exhausted and personnel have been requested from other states, she said.
Emergency Services Secretary Steph Cooke says communities across the state are also tired, including Gunnedah, who visited them on Saturday.
“This community has experienced eight floods in the last 12 months and it’s taking its toll on people,” she said.
“There is no silver bullet for what we are currently experiencing and will likely experience for a while,” she said.
The SES continues resupply operations, delivering food and medicines to flooded communities across an area of more than 40,000 square kilometers, roughly the size of Switzerland, Cooke said.
York said some communities would remain isolated for weeks, if not months.
In north-east Victoria, intense storm-driven rains are expected to trigger flash flooding with falls of up to 150mm in 24 hours in alpine areas.
North Victoria is experiencing major and moderate flooding and the rain combined with an already saturated catchment area and levee failures are expected to cause further and rapid increases.
The intense storms, which hit the eastern states, swept across South Australia on Saturday, with more than 423,000 lightning strikes and strong winds downing trees and damaging power infrastructure.
SA Power Networks on Sunday estimated that 100,000 customers had services affected and has brought in electrical teams from the highway to help with ongoing recovery work.
