Floods
Bureau of Meteorology (BOM) meteorologist Peter Otto said 55 millimetres of rain hit Melbourne overnight — the highest rainfall for March since 1929.
The average rainfall for Victoria in March is 50.1 mm.
Mr Otto said the wet weather was the result of remnants of ex-tropical cyclone Esther moving south from Queensland and the Northern Territory.
Heavy rainfall was expected to hit north-eastern Victoria today with possible totals of up to 100 mm.
"Melbourne showers will ease throughout the day and north-east storms will clear overnight," Mr Otto said.
A spokesman for the State Emergency Service (SES) said crews began responding to calls for help in the early hours of this morning as people woke up to the damage.
Disaster authorities said the incident occurred after heavy rains caused flooding in a mountainous area of the regency, dragging with it mud, logs and flood debris.
The flooding caused 900 people to evacuate their homes. At least 10 houses were washed away and completely destroyed. A further 60 houses were damaged, at least 11 of them severely.
Thunderstorms, heavy rain, strong winds and hail have affected the provinces of Yen Bai, Ha Giang, Tuyen Quang, Lai Chau, Lao Cai, Cao Bang and Son La.
In a study published in the journal Scientific Reports, the scientists examined geological and archaeological evidence, which revealed the flood "destroyed Kaifeng's inner city, entombing the city and its inhabitants within meters of silt and clay"—backing up evidence found in historical documents.
According to the team—led by Michael Storozum from Fudan University, China—the flood was so catastrophic because the walls of the city had partially collapsed during a siege, meaning that most of the floodwaters became trapped inside.

State Civil Defence said that some areas recorded over 280mm of rain in just 12 hours.
Among the worst hit are the cities of Guarujá, Santos and São Vicente. Roads have been blocked by fallen trees or landslides and houses damaged or destroyed. Dozens of people have been displaced, including 156 in Guarujá and 18 in São Vicente.
Civil Defence said that as many as 30 people are missing, raising fears the toll could rise further. As of 03 March, 15 fatalities had been reported in Guarujá, with 22 people still missing. Two people died in Santos (6 missing) and one in São Vicente (2 missing).

Two of the oldest weather stations in the country, PhoenixPark in Dublin and Malin Head in Donegal, had their wettest February since recording started in 1850.
Other weather stations that broke records were Shannon Airport, Co Clare (record length 74 years); Newport, Co Mayo (60 years); Claremorris, Co Mayo (56 years); Casement, Co Dublin (56 years); and Knock Airport (23 years).
Weather stations at Claremorris and Shannon Airport had once-in-100 years amounts of rainfall. Ballyhaise, Co Cavan, recorded once-in-90-years amounts of rain. Finner, Co Donegal; and Gurteen, Co Sligo, recorded once-in-60-years levels of rain.
Met Éireann long-term forecasters said the frequency of extreme weather such as the February floods could be attributed to climate change. However, they cautioned: "Without further detailed analysis, it's not possible to assess the role of climate change in this complex event."
The extreme weather, which mostly affected the northern half of the country, was caused by a strong stratospheric polar vortex that left the jet stream farther south than normal, steering a series of vigorous Atlantic depressions towards the northern half of the country.
The Office of Risk Management and National Contingencies (Copeco) almost 800 people hav been displaced as a result of the severe weather, mostly in the department of Cortés where3 shelters have been set up.
Overall 17,700 people were affected in the 6 northern departments of Gracias a Dios, Colón, Atlántida, Cortés, Yoro and Islas de la Bahía.
Some areas recorded more than 180mm of rain from late 29 February to early 02 March. A weather station in Mendanha recorded 61.4mm of rain in 1 hour late on 29 February, with 17.6mm falling in 15 minutes.
The rain triggered flooding and landslides causing severe damage in the Metropolitan Region of Rio, particularly western areas, and also in the Baixada Fluminense region of the state.
Dozens of roads were flooded, cars swept away and houses damaged. Two people were injured when a house collapsed in Magé, in Baixada Fluminense. Rio Metroplitan Civil Defense responded to 161 calls in total, many of them for collapsed or damaged buildings.
A UK average of 202.1mm has fallen this month, surpassing February 1990 when 193.4mm fell, the Met Office said.
Householders across the country were bracing themselves on Saturday night for further damaging high winds - of up to 90mph.
Some areas were deluged by more than a month's worth of rain in just 24 hours, as safety teams worked quickly to erect flood defences in vulnerable areas.
Heavy rain that began around 24 February increased levels of rivers in the province, including the Khoram, Kashkan and Poldekhtar, according to media reports. Rain also triggered some landslides in hilly areas of the province.
Roads have been damaged or blocked by flooding and landslides, and several bridges have been destroyed, leaving numerous villages cut off, particularly in Kuhdasht County, according to Tasnim News Agency.
