Sydney copped a mini twister and torrential rain on Friday from a low pressure system off the NSW coast, with forecasters warning of more bad weather at the weekend over a wider area.
The Twister was reported by residents of Bronte and Maroubra in Sydney's eastern suburbs on Friday morning - just 24 hours after a tornado devastated Lennox Head on the state's north coast.
"I watched it off the beach...it roared up here like a heavy wind storm," Jack Munro told News Limited.
The twister tore the roof off a garage in Macpherson Street, Bronte, about 11.25am, police said.
Two people - a woman and a child were home at the time, but neither was injured.
Most of the damage at Maroubra occurred about 1km inland, suggesting high winds may have been the likely cause of the damage, said the Bureau of Meteorology (BoM).
It issued a severe weather warning for eastern Sydney, including the CBD, shortly before 2pm (AEST), with advice not to drive, bicycle or walk through floodwaters.
"We are getting some fairly heavy rainfall and the totals are mounting up," said meteorologist Andrew Haigh, from the BoM.
"One of our storm spotters called in and said they were getting some pretty heavy rain ... that was causing localised flooding."
In the eight hours to 5pm (AEST) on Friday, Sydney recorded 63mm, with heavier falls in the city's northwest around Hornsby.
There was street flooding in a number of suburbs, including inner western Erskineville, where stormwater drains struggled to cope with the deluge.
The State Emergency Service (SES) responding to around 120 calls for assistance.
"We expect to get more as people come home from work and see that their homes haven't held up as well as they would have expected," SES spokesman Steve Delaney told AAP.
"We're looking mostly at water inundation, overflowing eves, some fallen trees and roof damage.
"The major part of the weather that has caused that damage has gone through Sydney.
"There will still be a bit of rain about, it's a big low-pressure system sitting off the coast and people should be aware of what's happening."
The BoM maintain a severe weather warning for flash flooding and damaging winds for parts of the mid-north coast, eastern parts of the Hunter region and Sydney metropolitan districts.
The Lennox Head tornado, destroying homes, toppled scores of trees and powerlines, injured six people and left another 25 homeless.
