Brace yourself: One months' rain in one day
Australia had a fairly dry winter but now, forecasters are predicting that the south-east of Australia could get a month’s rain in just 24 hours.
The Bureau of Meteorology has warned that some parts of NSW could have up to 100mm of rain which is well above the average rainfall for the entire month of October.
Most of Australia will be hit with grey skies except for Perth which will remain warm and sunny.

NSW and the ACT will receive the biggest downpours as well as gusty winds and possible thunderstorms.
Bureau of Meteorology forecaster Rob Taggart told news.com.au that a “transient” low pressure system was moving down from the state’s north west towards the coast.
“Transient low pressure systems don’t hang around, they move swiftly and they intensify as they move over the coast before moving away.”
“At this stage it looks like we should have a widespread 20-40mm of rain throughout the state on Monday.”
Further south, some areas are expected to receive one months’ worth of rain.
“On the south coast the rainfall totals may get over 100mm in some locations between Bermagui and Nowra."
He added, “Winter and September were very dry so I suspect for most places in Sydney a wet soggy day is probably much needed for the garden."
Mr Taggart warned that as well as the rain, strong winds are also expected.
“With the system we’re expecting very strong winds in southern and central parts of the NSW coast including the Hunter, Sydney and Central Coast,” he said.
“By the time people wake up on Tuesday morning most of the rainfall, aside from a few showers on the coast, will be gone. The whole event will be on Monday,” said Mr Taggart.
Melbourne will have scattered showers that will continue into Tuesday.
Hobart has the possibility of having showers today and temperatures will fall to around 15C on Tuesday.
Adelaide will have possible showers on Monday and Tuesday.
Perth will remain pleasant and warm while Darwin will have a high of 35C with possible showers and storms.
Brisbane is expected to have showers on Tuesday with up to 15mm of rain falling.
