Australia Australia's east coast brings month's worth of rain in just 24 hours
WA on alert as cyclone develops off the coast
Residents in Western Australia's north-west are bracing for heavy rain and destructive winds as the state's first cyclone of the season approaches. The Bureau of Meteorology (BOM) is predicting a tropical low, currently tracking parallel to the Kimberley coast, will intensify into a cyclone late tonight or early Friday before heading for the east Pilbara coast.
A month's worth of rain fell in parts of Victoria overnight as the east coast of Australia continues to suffer through unseasonably dreary weather.
Although the monster downfall has largely subsided, thunderstorms remain a possibility for Sydney and other parts of New South Wales with further fall are also tipped for the ACT, Victoria and Tasmania over the weekend.
As the grey, rainy conditions continue, Western Australia is predicted to see a sweltering heat wave over the next few days with the mercury rising into the high 30s.
A huge band of thunderstorms dragging in tropical moisture from the northwest of Australia rolled in across Melbourne overnight.
Heatwave remains across south-eastern states
Heatwave conditions across south-eastern states will continue today, with temperatures in some areas forecast to reach into the 40s. © Nine Crowds have flocked to beaches to escape the scorching temperatures across south-eastern parts of the country. Typically for a heatwave, the hottest areas have been across the interior, the past three days averaging a maximum of 44C at Marree in South Australia, 43.4C at Birdsville in Queensland and 42C at Smithville in NSW. Sydney yesterday had its hottest spell since last summer, averaging a maximum of 33C for the past three days.
'There was rainfall between 40 to 50mm across the city in the past 24 hours to 9am, with the CBD seeing the highest rainfall in 11 months and the airport recording the highest January rainfall in 26 years,' Weatherzone meteorologist Brett Dutschke told Daily Mail.
He said in some parts of northeastern Victoria they saw falls well over 100mm overnight - more than a month's worth of rain in a single day.
'Seven creeks recorded 144mm or three times the Jan average, and many other areas saw similar falls,' Mr Dutschke said.
At the moment it has dried out over Tasmania and central Victoria but showers and thunderstorms remain possible for parts of NSW, the ACT and other areas of Victoria over the weekend.
Southeast Queensland could also be hit with rain on Saturday and in the next few days.

'Thunderstorms are a chance today in Sydney and in the morning tomorrow,' Mr Dutschke said.
On Tuesday a large storm system is also set to move in across Sydney and other parts of NSW.
'Summer is on vacation for the south-east' as rain sets in and temperatures plummet
Flash flooding is forecast in the south-east today as heavy rainfall and cool conditions set in. But it is a nation of contrast as tropical rain persists in the north and the heat builds again in the west.According to Jonathan How, senior forecaster at the Bureau of Meteorology, it has been a rapid turn around from last week's heat.
Mr Dutschke said the unusually cold and rainy weather is due to changing climate cycles.
'We've got high amounts of humidity that have been building over the past few days and that high humidity is mostly because we are in La Nina,' he said.
'We've also had slow moving low pressure troughs so that moisture has been translated into heavy showers and thunderstorms.'
According to the The Bureau of Meteorology, La Nina weather patterns occur when equatorial trade winds become stronger, changing ocean surface currents and drawing cooler deep water up from below.
When this happens warm surface water piles up in the central and eastern tropical Pacific Ocean, where the Top End of Australia sits.
'The warming of ocean temperatures in the western Pacific means the area becomes more favourable for rising air, cloud development and rainfall,' BoM says on their website
WA warned of 'cyclonic conditions' while fire rages
Parts of Western Australia are bracing for severe weather as a tropical low brings heavy rain and dangerous winds to the Pilbara coast today. Residents in Exmouth, Minilya Roadhouse and Coral Bay are being warned of winds up to 85km per hour and possible flash floods as the system moves along the coast.The state's Department of Fire and Emergency Services (DFES) has issued a Blue Alert for people living in the warning area, urging them to prepare for dangerous conditions.
This means wetter weather, cooler days, warmer nights and heightened risk of cyclones.
While the east coast battles through the drizzly weather, Western Australians are bracing for a heatwave set to reach temperatures into the high 30s.
Perth is set to reach 35C this weekend with wind gusts of up to 70km/h.
Adelaide will stay mostly dry with temperatures around 25C and Darwin will hit 30C with tropical thunderstorms forecast overnight.

BBL10: What happens if the Big Bash final is washed out? .
BBL10: What happens if the Big Bash final is washed out? In order to constitute a game, each team must face a minimum of five overs each. With rain expected on Saturday, the game will be moved to Sunday if they can not fit in the overs due to rain. The game would be played on Sunday morning as players are set to fly to New Zealand for the upcoming T20 series, ensuring they can do the necessary two-week quarantine period. If this is not achieved, the rules state that the trophy will be awarded to the home team, which is the Sydney Sixers.
