NSW, QLD, Victoria Weather: Cold front will bring heavy rain, winds, flood warning

Australia’s southeast faces a wet and windy weekend with a complex weather system bringing torrential downpours and flooding across several states as temperatures drop again.

“We have seen torrential rain and strong winds across south-east Australia for the past 36 hours and as a result there is fairly widespread light to moderate flooding across central west and south-west NSW,” said Tom Saunders, Sky News Weather’s chief meteorologist.

“But the heaviest rain is now shifting further north.”

The Bureau of Meteorology currently has severe weather warnings for damaging winds for parts of NSW and ACT.

The warnings apply to people in Illawarra and parts of the South Coast, Southern Tablelands, Snowy Mountains, ACT and Central Tablelands.

“A complex low-pressure system moving across the eastern Great Australian Bight and an associated trough and cold front are causing strong westerly to northwesterly winds over south-east NSW today,” the BOM said Friday morning.

“Harmful winds with peak gusts of around 90 km/h are expected over the high terrain and eastern slopes from the Alps and along the Great Dividing Range from Bombala to south of around Crookwell and also over the Illawarra from escarpment to coast. These conditions may continue into this evening before weakening overnight or before sunrise on Saturday. Saturated soils in the Central Tablelands and Illawarra pose an increased risk of gusty winds knocking down trees and power lines.

Sites that may be affected include Wollongong, Nowra, Bowral, Braidwood, Goulburn, Cooma, Bredbo, Adaminaby and Nimmitabel.

The heavy rain band is now moving towards north NSW and south Queensland, but a low-pressure system means showers will continue across south-east Australia over the weekend.

BOM meteorologist Jonathan How said there was a possibility of major flooding in parts of NSW and Victoria.

“In the southeast, a series of troughs are sustaining these cold, blustery and rainy conditions,” he said.

Tasmania, southern South Australia, Victoria and the west side of the NSW Southern and Central Ranges can expect light to moderate showers through Sunday.

Farther north, some parts of north NSW and south Queensland will see up to 20mm of rain on Friday and Saturday, but the band of rain is expected to ease off the Queensland coast by Saturday afternoon.

At the same time, cold air moving up from the south will cause mercury to fall below 15 degrees in much of the southeast by Saturday after above-average temperatures earlier in the week.

Showers continue next week with a southerly forecast to bring showers to the NSW coast – before another massive band of rain hits from the west through Wednesday, in a repeat this week.

“It doesn’t look quite as intense at this stage, but there are still some moderate to severe falls possible over the next eight days.”

Over in Western Australia, showers and strong winds are expected around Perth early next week.
