A month's worth of rain is set to fall in Melbourne over the next two days, with thunderstorms and hail likely to accompany the downpour.
Melbourne is set for a downpour, with a month's
 worth of rain forecast for Thursday and Friday
.
The Bureau of Meteorology is predicting up to 15 millimetres of rain for Thursday, with another 25 to 80 millimetres expected on Friday - almost up to double the average May rainfall of 56 millimetres.

Senior forecaster Rod Dickson said a powerful cold front arriving on Thursday could produce hail, and will see a good dump of snow of down to 900 metres in the state's alpine areas.

Tornadoes destroy homes in Tennessee, Kentucky as wild storms hit central US

At least five people have been killed as severe thunderstorms swept through the central US, spawning tornadoes that flattened homes, gale force winds and widespread flooding.
Gio Rodriguez, 8, sits outside his Tennessee home after a
 storm which caused chaos across much of the central United States.
The system, stretching from Texas to the Canadian Maritime provinces, had prompted several emergency declarations even before the dangerous storms arrived.

Storm crews confirmed two tornadoes touched down in middle Tennessee and Kentucky, with maximum-sustained winds of 193 kilometres per hour.

One of the tornados struck in south-central Kentucky, causing homes to collapse and cars to flip over, and a 79-year-old woman died after her Adairville home was destroyed, the Logan County Sheriff's Office said.

Wild storm wreaks havoc on NSW north coast, with more storms forecast

Severe thunderstorms have caused widespread damage on the New South Wales north coast this afternoon.
The storm ripped roofs off a number of buildings
 in Maclean, including the Clarence Hotel.
The State Emergency Service has reported receiving around 60 calls for help.

SES spokesperson, Jenny North, said most of the damage was in and around the town of Maclean, where severe winds ripped roofs off a number of buildings and brought down powerlines.

A school in Maclean also received some damage, and there were also people camping at the showground, which suffered damage.

"We have had reports of damage to the showground roof, various council buildings and even the Maclean SES has had some damage," Ms North said.

Melbourne weather: When the rain is likely to hit your area hardest

Melbourne is set to be lashed with more than 100 millimetres of rain – almost double its December average rainfall – over Friday and Saturday alone, with thunderstorms and hail likely to accompany the downpour.

A severe weather warning has been issued for all of Victoria as the bureau prepares for what could be the state's most significant rain event in more than 20 years.

It is difficult for weather forecasters to give a precise hour-by-hour timeline of when rainfall is likely to hit any one suburb.

"Showers and thunderstorms can bubble up very quickly during a rain event like this", says Keris Arndt, senior forecaster at the Bureau of Meteorology

Get ready for deluge

Records are expected to be broken in the next two days with the Bureau of Meteorology expecting the Goulburn Valley to be hit hard by thunderstorms bringing from 100 mm to 200 mm of rainfall.

Senior forecaster Richard Carlyon said the bureau made the unprecedented move to issue severe weather and flood warnings on Wednesday to give people time to prepare for the band of heavy rain and thunderstorms slowly moving across southern Australia today and tomorrow.

Desperate: Some farmers have worked during the
 night frantically harvesting their crops, in a race
 to beat the bumper rainfall.
‘‘We had a week of hot, humid weather and north-easterly winds have brought tropical air full of moisture that will combine with a strong low-pressure system over the Mallee, where it will develop and then slowly move east,’’ Mr Carlyon said.

‘‘There will be substantial rainfall, the Goulburn Valley’s December rainfall average of 40 mm will be reached and some locations across Victoria might end up with their summer average in the first two days of December.’’

The heavy rain is forecast to start falling at the end of this morning, with 50 mm to 80 mm predicted, while tomorrow is expected to bring a soaking of 50 mm to 100 mm.

There could be large hail and the possibility of damaging winds across both days.

Mr Carlyon said a few showers would be left on Sunday and there are also potential showers forecast on Monday and Tuesday that could have a significant impact on river levels.

‘‘I think there will be records broken, it’s difficult to compare to the 2010 weather event, but basic rainfall records for either one or two days are likely to be broken,’’ he said.

Widespread flooding is likely from today onwards in the catchments and people are asked to stay informed and monitor conditions.

The main rivers under flood watch are the Ovens, King, Broken and the Goulburn. The Seven and Castle creeks are also under a flood watch and flooding may occur on the Campaspe River.

‘‘Plans are being cancelled or amended and I think if you can, it’s best to stay indoors,’’ Mr Carlyon said.

‘‘Local roads may be closed and low bridges may be underwater. Water crossings along streams and rivers will become dangerous as water levels rise.’’

The bureau has also released an advice warning for the potential of brown rot to form on stone fruit because of the high humidity levels the storms will bring.

Victorian Farmers Association president David Jochinke said the low-pressure system may dump more than 300 mm of rain in Victoria’s north-east, which could spoil remaining crops.

Some farmers have worked during the night frantically harvesting their crops, in a race to beat the bumper rainfall.

Goulburn-Murray Water is urging its customers and northern Victorian communities to keep an eye on updates from the bureau ahead of significant rain expected.

G-MW’s managing director Pat Lennon said the customer operations team was monitoring the situation closely and working with storage staff, the bureau and State Emergency Services representatives.

‘‘Some of G-MW’s water storages are already near capacity and others may receive significant inflows. We are currently preparing for the forecast conditions in accordance with our operational arrangements,’’ Mr Lennon said.

‘‘Please keep an eye on BOM updates and heed any flood advice they may issue. Flood warnings will be issued by BOM.

‘‘People living near rivers, creeks, storages need to monitor the situation and prepare themselves and their properties, according to their flood plan.’’ 

  • G-MW customers are reminded that before pumping any excess flood water from their property into G-MW irrigation or drainage channels, they must first seek permission from a planner via WaterLINE on 1300 469 469. Residents can monitor flood warnings on the Emergency Management website at www.emv.vic.gov.au and request emergency assistance by phoning the State Emergency Service on 132 500.

Tropical thunderstorms are set to grow stronger as the world warms

Thunderstorms are set to become more intense throughout the tropics and subtropics this century as a result of climate change, according to new research.

Thunderstorms are among nature’s most spectacular phenomena, producing lightning, heavy rainfall, and sometimes awe-inspiring cloud formations. But they also have a range of important impacts on humans and ecosystems.

For instance, lightning produced by thunderstorms is an important trigger for bushfires globally, while the hailstorm that hit Sydney in April 1999 remains Australia’s costliest ever natural disaster.

Adelaide pelted with huge hailstones as severe storm follows 31C heat

The Bureau of Meteorology says large hail
fell through the north-eastern areas
of the Adelaide metropolitan area.
Sudden and severe thunderstorms swept across Adelaide on Friday afternoon, with huge hailstones hitting streets across the city centre.
The system swept south-east on a day when there was only a 40% chance of rain predicted. Adelaide experienced 31C heat before the storm broke, bringing wind gusts of more than 90km/h.

The Bureau of Meteorology warned wind gusts of more than 125 km/h were possible in the North East Pastoral, Mid North and Riverland areas.

Localised flash flooding was reported as some areas received up to 10mm of rain in as many minutes. The bureau said areas that may be particularly affected include Adelaide, Whyalla, Renmark, Mount Gambier, Leigh Creek and Moomba.
