NSW wild weather damage as 'significant' clean-up begins — in pictures

Residents are bracing for a "significant" cleanup after parts of NSW were inundated with a month's worth of rain in 24 hours.

Dozens of warnings remain active across the state, as many towns still face flood warnings from the torrential downpour.

Heavy rainfall and damaging winds have wreaked havoc on communities west of Sydney, with swollen rivers still threatening residents' homes.

Evacuation orders remain in place for towns along the Napean and Hawkesbury rivers. The Hawkesbury is predicted to peak near 9.6 metres, with nearby towns bracing for flooding.

Sixty emergency warnings remain active across the state, with NSW State Emergency Services (SES) issuing at least a dozen evacuation orders due to flooding concerns.

Residents and business owners cleared to return are assessing the damage to their properties after they were hit with 200mm to 250mm of rain in 24 hours.

NSW SES Chief Superintendent Dallas Burnes said the state clean-up will be "significant".

"We have seen the highest peak and we’re now following that water downstream and making sure we warn the communities in its path," she told Nine's Weekend Today.

The wild weather has caused landslides, flash flooding, and inundated homes, and emergency service workers have performed over 200 flood rescues.
