Parts of NSW have been buffeted by high winds, with two people injured by flying building cladding, glass left shattered in a CBD high-rise and Sydney Airport forced to cancel flights.

Severe damage has been reported across Sydney, and the NSW Bureau of Meteorology (BOM) issued a severe weather warning for Friday and Saturday.

At the entrance to Wynyard Station in the CBD, two people were injured when cladding was blown off a building in Clarence Street.

A man in his 30s suffered injuries to his foot, and a woman, also in her 30s, had injuries to her arm.

At nearby Barangaroo, a large piece of double-glazed glass shattered on the fourth floor of International House.

The glass fell onto pedestrian alleyway Scotch Row which remains closed.

Police initially established an exclusion zone but all roads have since been re-opened.

In Hurstville in the south-west, police said a large satellite dish has been blown off a building near the Waratah Private Hospital.

In the north at Seaforth, a tree brought down powerlines on a car.

A furniture store at Caringbah, in Sydney's south, had part of their front wall collapse due to the wind on Friday afternoon.

No-one was injured and the store believes they will be able to stay open as work is completed to secure the building.

Flight cancellations due to 104kph winds

At Sydney Airport, hundreds of people are stranded after their flights were cancelled due to hazardous wind.

Passengers are facing significant delays of between 60 and 90 minutes and some have been told they cannot get a flight until Saturday afternoon.

Winds of up to 104 kilometres per hour were recorded at the airport at 1:50pm.

Passengers should check with their airline for information and updates.

Electricity provider Ausgrid said thousands of homes and businesses were without power across Sydney and the Central Coast.

Ausgrid has restored power to 6,000 customers and are continuing repairs across the network to connect isolated suburbs.

Over 1,000 western Sydney residents are also without power due to tree branches on powerlines.

The highest wind gusts recorded around the state on Friday morning were 106 kilometres per hour at Nowra, 104kph at Albion Park and 96kph at Kurnell.

The State Emergency Service (SES) said it had received more than 720 callouts due to damage caused by strong winds.

The southern suburbs and central coast have felt most of the brunt, with the SES advising people in those areas to stay indoors until winds ease.

Roof blown off onto Wollongong radiology centre

Strong winds have flattened fences, forced trees onto roads and blown a roof off a commercial building in Wollongong.

Alex McFadden from the Illawarra South Coast SES said there had been a spike in calls for assistance.

"We've got teams out in Wollongong in the northern parts of the shire and also down into Shoalhaven as well," he said.

A roof has blown off onto a radiology centre next to Wollongong Hospital, closing a section of Crown Street.

Endeavour Energy said power had been cut to 2,000 homes in Wollongong and 1,000 around Gerringong.

On Wednesday, one man died and another was critically injured following two wall collapses on construction sites in Sydney blamed on wild wind which also brought down trees and powerlines across the city.

Residents were without power in a number of suburbs, and transport was affected across Sydney and parts of the state.
