Residents in theand Illawarra regions were warned flash flooding is ‘essentially guaranteed’ with three months’ worth of rain to fall in the next five days.
The Bureau of Meteorology (BoM) issued a severe weather alert for metropolitan Sydney, Illawarra and parts of the South Coast, Central Tablelands and Southern Tablelands on Saturday morning.
‘Residents living between Port Stephens and Batemans Bay, including Sydney and the Illawarra, are likely to see multiple days of heavy rainfall that will lead to flash and riverine flooding,’ BoM meteorologist Dean Narramore said.

Parts of the coast between metropolitan Sydney and Wollongong are expected to see over 300mm of rain in the next five days.
Sydney’s average July rainfall is just 96mm.
The weather system comes on the first weekend of school holidays in the state, and drivers are being asked to take extreme caution.
‘We know floodwater is extremely dangerous, especially for drivers. If the road is flooded, turn around and find another way,’ Transport for NSW’s Roger Weeks says.

Routes in and out of Sydney are likely to have congestion and heavy traffic is expected at known pinch points, particularly around Sydney Airport.
Hazardous surf and swell conditions could also develop in coming days.
The BOM said on Friday afternoon the system may develop into an east coast low on Sunday or Monday, prolonging the persistent rain into next week.
Heavy falls across the weekend could to lead to rising river levels as the deluge hits multiple already-saturated catchments.

‘We know these are quite dangerous systems,’ Bureau of Meteorology Manager of Hazard Preparedness and Response Jane Golding told media on Friday.
‘They’ve been known to produce some widespread flooding in the past, and that’s certainly on the cards for the next few days.’
Ms Golding said the deluge could lead to flash flooding and landslips.
‘The landscape is quite vulnerable at the moment and the water can move very quickly down the slopes and through the waterways,’ she said.
Sky News Weather channel senior meteorologist Tom Saunders said ‘flash flooding and river flooding is essentially guaranteed’ in catchments forecast to see high rainfall.

The weather system over Sydney is forecast to pick up around midday on Saturday with heavy rain set to stay over the region heading into Sunday.
Some regions on NSW’s south coast already saw over 150mm of heavy rainfall overnight as the system moved north towards Sydney.
The large rain-band formed over the Northern Territory and Queensland earlier this week moved east overnight to focus over southeast Queensland.
Regions from Mount Isa to the Gold Coast saw moderate rain overnight with Longreach receiving over 36mm, Rockhampton 35.6mm, Miles 26.6mm and the Gold Coast 27mm.
Brisbane can expect to see rain on Saturday before the NT/QLD rain-band largely clears late Saturday night
Rain is forecast to clear up in the state’s southeast from Saturday night as the system’s end moves east.
Rain will continue over Queensland’s northeast, largely hanging around the coastline between Cairns and Mackay.
‘At this stage we’re not expecting this rainfall to cause any major flood risk,’ Mr Narramore said.
‘That flooding risk will be concentrated around the central NSW coast.’

Darwin is forecast to see a bit of cloud on Saturday as the last of this week’s rain moves east, leaving a sunny sky for Sunday and the week ahead.
The sunshine will be accompanied by high temperatures peaking at 28C and 29C through to next Tuesday with lows remaining in the high teens.
Unfortunately Canberrians are expected to cop some of NSW’s rainfall with showers forecast until Monday.
Minimum temperatures are set to stay just above freezing level at 5C and 6C with maximum temperatures in the low teens.
Residents in Canberra are forecast to see showers through to Monday due to the large rain system sitting on NSW’s central coast
Melbourne is forecast for a cloudy Saturday before the grey partially breaks up to make room for a little bit of sunshine from Sunday.
Hobart will also see that cloudy weather through to Tuesday next week with minimum temperatures consistently sitting at 5C and maximums in the mid teens.
Adelaide is expected to see cloudy weather on Saturday which will partially clear on Sunday before turning sunny early next week.
