Weather Sydney, Brisbane: When 300mm rain bomb is set to hit Australia’s east coast

When 300mm rain bomb is set to strike the east coast of Australia – and the cities where it’s poised to ruin the weekend

  • Heavy rain will be bucketing down across NSW and QLD for the next seven days
  • The intense wet weather may also bring damaging winds and possible flooding
  •  It’s due to tropical moisture feeding into an upper-level trough over the east
  • Weatherzone claims the severe wet weather is ‘highly unusual’ for north QLD 

Widespread rainfall will bucket down across parts of New South Wales and Queensland, with up to 300mm set to drench cities and towns along the east coast over the next seven days.

A month’s worth of rain is expected to batter Australia’s east in the next five days alone, starting on Friday.  

Gusty winds and possible moderate to major floods are also forecast for the NSW coast, as well as north and central Queensland. 

The severe wet weather is because of tropical moisture which is feeding into an upper-level trough over the east coast, according to Weatherzone.

The system will hit most parts of the Australian east coast spanning roughly Cooktown in Queensland’s north to Bateman’s Bay on the NSW south coast over the next week. 

Heavy rainfall and gusty winds are expected to lash parts of NSW and Queensland over the coming seven days . (Pictured: A woman walks through the rain with an umbrella in Parramatta, Sydney)

Weatherzone meteorologist Joel Pippard said that north Queensland will be the hardest hit by the weather on Friday from Townsville to Cooktown.

The NSW south coast between Illawarra and Sydney is forecast to cop the heaviest drenching along the east coast on Saturday before the system heads further north.

A low pressure trough will then deepen along the eastern coast at the time, increasing the amount of rain set to fall. 

‘That little bit is expected to spread up the coast to the Central Coast, Blue Mountains, Hunter and Newcastle regions and possibly up to the mid-north coast,’ the meterologist continued. 

Townsville, in north-eastern Queensland, will be most impacted by the severe wet weather on Friday, according to Weatherzone

The combined weather events may result in regions in NSW experiencing more than 100mm of rain within 24 hours.

Weatherzone suggests those NSW and Queensland coastal areas, except for the Central Coast, may experience moderate to major flooding.

Those areas will also have the highest probability of receiving up to 300mm of rain fall for the week. 

Sydney is likely to experience falls of 100mm to 200mm over the seven days. Brisbane may see similar levels. 

Rain will continue bucketing down for parts of eastern NSW and Queensland through to Wednesday.

Mr Pippard pointed out that, while the heavy downpour and gusty winds are normal weather for Sydney at this time of year, it’s uncommon for Queensland.

‘Northern Queensland is in the dry season, but moisture is coming straight down from the equator. 

‘It’s very unusual (weather for Queensland).’

The meteorologist said the severe wet weather should dissipate next Thursday.
