Federal Emergency Management Minister Murray Watt said Victoria faced “several severe flooding” with more rain forecast this weekend.
Watt told Australian Broadcasting Corp.
“So this is a very serious situation and the report I have received is that we… are probably looking at up to 9,000 homes flooded in northern Victoria and potentially close to 34,000 Victorian homes flooded. or isolated,” Watt added.
Two people drowned and two were reported missing in Victoria and New South Wales over the past week.
The most recent death was a 71-year-old man found dead Saturday in floodwaters in the backyard of his home in Rochester, a central Victorian town about 180 miles from the state capital Melbourne. km (110 miles) to the north.
Tim Wiebusch, chief executive of Emergency Services Victoria, estimated 85 per cent of Rochester was flooded by the Campaspe River over the weekend.
Wiebusch said the northern Victorian town of Kerang is likely to be isolated for up to seven days when the Loddon River peaks on Wednesday or Thursday.
“While we have some communities where rivers are starting to recede, there are still many rivers and communities that are threatened by major flooding in the coming days,” said Wiebusch.
Many schools and roads have been closed across south-east Australia and thousands of people have had to evacuate their homes.
October is usually the beginning of wildfire season in three states that are suffering and flooding is near record.
The landscape often withers in the Southern Hemisphere spring, and fire danger escalates in the summer. But the Bureau of Meteorology last month announced a third consecutive La Niña weather pattern, associated with above-average rainfall in eastern Australia, was underway in the Pacific.
The office forecasts that the La Niña event could peak in the current Southern Hemisphere spring and return to neutral conditions early next year.
Professor Julie Arblaster from the School of Earth, Atmosphere and Environment at Monash University in Melbourne describes three consecutive La Niñas as very rare.
“Precipitation and flooding are consistent with our understanding of how a La Niña event impacts our region,” Arblaster said in a statement.
Other climate dynamics – Positive Southern Annular Mode and Negative Indian Ocean Dipole – also aligned to yield above-average rainfall to eastern Australia.
