"Think Victoria and disasters and you’ll think bushfires. But floods can hit –
just not as often.
Today is one of those days, with much of the state under a flood watch. Premier
Dan Andrews says the floods are likely to be the most significant in years.
Evacuations are likely.
Floodwaters are pushing down the Goulburn to the Murray. Major flooding in the
Maribyrnong, which runs through towns and Melbourne’s west. Emergency services
say evacuations may be necessary. Towns are sandbagging flood-prone areas. Some
have been cut off by rising waters.
The state’s largest dam, Dartmouth, is spilling over. So is Lake Eildon’s dam.
And the Thomson dam may well spill this weekend, for the first time in decades.
This isn’t the last of it – Victoria’s emergency management commissioner Andrew
Crisp has warned intense rains and floods could last up to six to eight weeks.
Even as the rest of the eastern seaboard has faced the brunt of three
consecutive La Niña years, Victoria has had little flooding until now.
Tasmania, too, is facing rare flooding, while flood-weary New South Wales is
bracing for more.
These heavy rains are unusual. Dense cloud bands have crossed the desert,
carrying moisture evaporating from seas off north-west Australia. Rain has
fallen across almost the entire continent in the last two weeks. Our rain
events are usually regional – not national."
