NSW weather warning: Central Coast, Sydney brace for thunderstorms, heavy rain, flash flooding, dangerous surf

Severe storms have battered Victoria's Great Ocean Road, causing flash flooding that swept approximately 20 cars into the ocean and forced 300 campers to evacuate.

Parts of New South Wales are bracing for wild weather as severe thunderstorms sweep across the state, bringing the threat of flash flooding, torrential rain and hazardous surf.

The Bureau of Meteorology (BOM) has warned that a severe thunderstorm detected on Saturday morning is likely to unleash heavy rainfall capable of triggering flash flooding.

The system is expected to lash the NSW Central Coast mid-morning, particularly around Spencer, Lower Mangrove and Mount White, before tracking towards Calga by midday.

In Sydney, the same system has already drenched suburbs, with 35mm recorded in just 30 minutes at North Parramatta.

BOM Meteorologist Angus Hines said rainfall totals could vary widely, but coastal communities are likely to be hardest hit.

“The forecast is showing quite a wide range, and that’s when thunderstorms are key contributors to rain,” he said.

“Some suburbs closer to the coast might cop the brunt of it, 50-70mm, while other parts could get 10-20mm”

Cronulla Beach has been included in a damaging surf warning for waves reaching up to five metres, though Mr Hines cautioned that the dangerous swell may impact beaches up the Sydney coastline as well.

“It could push into the Sydney coastline. Rough seas are expected on Sydney’s waters...it could be dangerous coastal conditions,” he said.

The NSW SES is urging residents to stay clear of fallen powerlines, creeks and storm drains, and to watch for debris or fallen trees on the road.

They are also reminding residents to not walk, ride bikes or drive through flood water.

Meanwhile, communities along Victoria’s Great Ocean Road are continuing recovery efforts after a record “rain bomb” caused flash flooding that swept cars into sea and forced hundreds to evacuate campgrounds and coastal towns.

More than 180mm of rain fell in less than five hours on Thursday afternoon, sending torrents of water surging through low-lying areas around Wye River, Kennett River, Cumberland River, Lorne and Apollo Bay.

Emergency services conducted multiple rescue operations as fast-rising water tore through campgrounds and cut off sections of the coastal highway.

For emergency help in flood and storms, ring the SES on 132 500.
