Rain bomb alert as mammoth weather system moves across Australia and temperatures plunge - as city records wettest day of the year
Wet weather lashed most of the country in the past week, with every state and territory recording widespread rain - the most so far for the year for many locations.
A severe low-pressure system along with a cold front and significant trough developed across south-west Western Australia on Sunday.
Perth experienced its wettest day of the year after it was hit with damaging winds, heavy rain, hail, and thunderstorms.
The wet weather system is forecast to crawl eastwards on Monday, with Bureau of Meteorology forecaster Angus Hines warning it will bring inclement conditions.
'This front moves through the southern half of Western Australia and into South Australia on Monday with showers and plenty of hail,' he said.
'Showers will ease across the south-east, with a further 2-10mm. Patchy falls across much of South Australia, NSW and southern Queensland on Tuesday, with a chance of rain in Victoria and Tasmania.'
Mr Hines explained the weather system would also bring with it colder air and snow for the mountains in NSW and Victoria.
He added cold winds and patchy showers would continue, with light wet weather for most places south of a line stretching across the nation from Perth to Port Macquarie.
A dry day is forecast for Thursday, but showers and cool winds are expected on Friday for the country's south-east.
'Some heavier falls or thunderstorms are possible, but we'll have to get closer to the time to confirm the details,' Mr Hines said.
'A rainband could form over north-east Queensland, and yet another rain-bringing front is just dusting its shoes by the door of the west coast heading into next weekend.'
Weatherzone meteorologist Yoska Hernandez added a colossal low-pressure system, spanning nearly half the size of the country, would also bring chilly temperatures to southern and eastern parts of Australia this week.
As the massive low drifts east, temperatures in Melbourne and Adelaide are expected to struggle to reach the mid-teens.
Canberra may barely pass a maximum of 10C each day, with the mercury dropping to a frosty minimum of 0C on Thursday.
Sydney's minimum temperatures will remain below 10C for the week, and reach chilly maximums in the mid-teens as well.
The mercury is forecast to dip to a minimum of 3C in Hobart, with the days reaching a maximum temperature of between 11C and 13C.

Iona strengthens to a Category 3 hurricane in the central Pacific off southern Hawaii
Iona strengthened to a Category 3 hurricane several hundred miles south-southeast of Hawaii, but poses no threat to the islands, the U.S. National Hurricane Center said Tuesday. Iona is one of two major weather systems in the central Pacific Ocean. In its latest advisory, the Miami-based center said Iona was about 790 miles (1,271 kilometers) off Honolulu, with maximum sustained winds near 115 mph (185 kph). Additional strengthening is forecast later on Tuesday, with steady weakening expected to begin by Wednesday. Hurricane Iona is the first named storm of the hurricane season in the central Pacific and emerged Sunday from a tropical depression. It continues to trek west over warm, open waters. No coastal watches or warnings were in effect. Meanwhile, Tropical Storm Keli is further south with maximum sustained winds of 40 mph (65 kph). It was about 960 miles (1,550 kilometers) southeast of Honolulu and was moving west at about 12 mph (19 kph). The administrator of the Hawaii Emergency Management Agency on Monday hosted a statewide conference call with all counties, during which the National Weather Service provided an assessment and status of the storms. 'All counties are monitoring,' agency spokesperson Kiele Amundson said in an email. Another indirect impact from the weather systems could be swells, but they are relatively small and moving westward and won't create anything significant, said Derek Wroe with the National Weather Service in Honolulu.. However, a large swell is headed toward Hawaii after being generated several hundred miles east of New Zealand. It's expected to arrive in Hawaii by Thursday, about the same time the storms pass the state. ' People might wrongly attribute the swell energy to be from these tropical systems, but they're actually not,' he said.

Possible Derecho threatens the Northern Plains
Millions of Americans are bracing for hurricane-force winds as a severe thunderstorm is set to slam into the Northern Plains on Monday. AccuWeather experts said the system could evolve into a derecho, a rare but destructive complex of thunderstorms that is expected to unleash wind gusts of up to 100 mph across four states. The greatest threat zone includes parts of South Dakota, Nebraska, Minnesota and Iowa, which could also experience hail, flash flooding and tornadoes. The potential derecho is expected to reach its peak strength sometime in the late afternoon or early evening in eastern South Dakota or southern Minnesota. Meteorologist Brandon Buckingham said: 'The high risk of severe weather Monday afternoon through Tuesday morning encompasses a large swath of the 'Corn Belt' of the US, which poses additional economic and logistical risks to the region.' Residents are urged to prepare emergency supplies, including medications, flashlights, batteries and a fully charged cellphone. Officials recommend seeking shelter in a basement or interior room if a severe thunderstorm or tornado warning is issued. 'People should have multiple ways to receive weather alerts, especially at night when most are sleeping,' AccuWeather said in a statement. 'Do not rely on outdoor sirens alone.' Derechos are defined by straight-line winds exceeding 58 mph across a path of more than 250 miles. They often topple trees, destroy buildings, and cause long-lasting power outages. A recent derecho in April knocked out power across eastern Ohio and western Pennsylvania for several days. The storm is expected to form over the High Plains, fueled by a dome of high pressure and a surge of tropical moisture. As thunderstorms initially develop in Montana and the Dakotas Monday afternoon, it is possible for storms to congeal into a powerful derecho,' said Buckingham. 'In turn, AccuWeather meteorologists have added a high risk for severe thunderstorms from eastern South Dakota into southwestern Minnesota and northwestern Iowa.' Major airports, including Minneapolis-St. Paul International, may experience flight delays or cancellations. Ground transportation could also be disrupted, especially for high-profile vehicles vulnerable to intense wind gusts. Power grids already strained by ongoing heatwaves could face added stress, potentially prolonging outages, AccuWeather warned. A heat dome over the central US is driving the volatile weather expected this week. Travelers on the road or in the air should be cautious, as the combination of soaring heat and severe storms could cause power outages and disrupt transportation. AccuWeather warned the storm system may continue advancing into the Ohio Valley and Great Lakes on Tuesday, threatening Milwaukee, Chicago and Indianapolis with flooding rain and damaging wind during the morning commute. 'Enough instability may be present across the Midwest Tuesday morning for any complex of thunderstorms to maintain intensity continuing the risks for damaging wind gusts and flash flooding,' adds Buckingham. By Wednesday, the storm is expected to push into New England and the Mid-Atlantic, where torrential downpours could trigger flash flooding, particularly in areas already saturated from recent storms. Severe weather threats will persist Thursday in parts of the mid-Atlantic as the risk moves south to include the Carolinas.
