Australia’s east coast is set to endure a hellish week as a powerful weather system brings heavy rainfall, flooding and winds ‘strong enough to bring down power lines’.
The low pressure system drenched the Gold Coast, Central Coast and Sydney on Sunday with some parts of the NSW capital copping more than 100mm of rain.
Sydney, Canberra and Melbourne are all experiencing rain as the system moves down the NSW South Coast towards Victoria on Monday. On top of the wet weather, the NSW capital is also experiencing gale force winds of up to 60kmh.
BOM Meteorologist Grace Legge said the system will continue to have dangerous consequences with severe weather warnings in place for NSW, ACT and Victoria.
‘From Monday we will likely see locally damaging winds strong enough to bring down trees and power lines with the main area of concern along the coast south of Taree and severe weather warnings are current,’ Ms Legge said.
‘The heavier rain fall is forecast to shift to the Illawarra and South Coast and possibly far east Gippsland and Victoria with a flood watch already out for some catchments and the potential for river rises along coastal parts,’ Ms Legge continued.
‘Thunder storms embedded in the system may produce locally heavy falls leading to flash flooding.’
Up to 35mm of rain is expected in Sydney on Monday with moderate gale force winds of up to 60kmh expected for Monday night.
The Sydney CBD has already experienced 85mm rain in the last 24 hours with Turramurra in the Upper North Shore receiving the most in the city at 115mm.

Relief for Sydneysiders will finally come on Wednesday, when the wet weather will be replaced with mostly sunny skies – although southwesterly winds of up to 20kmh will remain with a slight chance of rain returning on Thursday.
‘Wind and rain are not the only concern with large and powerful waves forecast for Monday and Tuesday. This may result in hazardous beach conditions with very heavy surf and coastal erosion especially for south facing surf zones,’ Ms Legge said.
‘This included the vulnerable Central Coast which suffered significant erosion last week associated with the recent Tasman low. Hazardous surf conditions are likely to ease from later Wednesday as the system pulls away from the coast.’
NSW skiers are rejoicing at up to 20mm of snow in Thredbo on Monday, although strong gale force winds of up to 75kmh make conditions quite hostile.
