Three months of rain will explode over Australia in just FIVE days (2022)

Residents in the Sydney and 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.

Two Australian Defence Force helicopters will be available to assist with rescues as areas of NSW brace for intense rainfall and possible flooding.

The federal government approved ADF support at the request of NSW on Friday night, with 100 troops also available from Sunday onwards, Emergency Management Minister Murray Watt said.

'I want to assure people that the federal government … is 100 per cent prepared for what might lie ahead,' Mr Watt said from Brisbane on Saturday.

'One of the things that we've learned over the last couple of years is that when we don't have a federal government that takes responsibility and isn't proactive, bad things can happen.'

Forecast models (above) forecast the greater Sydney region to see at least 300mm of rain in the next five days

Mr Watt said he was hopeful the ADF resources wouldn't be needed, but they will be ready to assist.

'We're not exactly sure how this weather event will pan out, but it could be quite serious over the next couple of days,' he 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.

Catchments around the Hawkesbury Nepean River have been flagged as at risk of major flooding.

Hawkesbury Nepean SES began moving 2,000 sandbags to help prevent flood damage in the region.

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.

NSW State Emergency Service spokespersonGreg Nash warned school holiday travellers to take extra care amid the dangerous conditions.

'With people wanting to travel for the school holidays, we are urging people to review their plan. Make sure that they are able to go get to the destination, how they are going to get there and if it is safe to go,' he told Daily Mail Australia.

NSW SES warned residents in the Hawkesbury Nepean region to prepare for flooding and make an emergency plan (pictured, NSW SES Hawkesbury Nepean Valley evacuation routes)

'For the people that have travelled already or still plan to, when you arrive talk to the family that you are staying with or the staff of where you are staying. Find out from there what emergency plan is, be informed and be sure that you know what to do and where to go at your holiday destination.'

'As people are travelling, we want people to make smart, safe decisions. If you find flood water, stop, turn around and find another way. Driving through flood water isn't worth the risk to you or the people in the car.'

Routes in and out of Sydney are likely to see congestion and heavy traffic 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.

Sydneysiders can expect wet weather this weekend and heading into next week as an possible east coast low forms

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.
