Strong winds will continue to lash parts of NSW throughout the weekend but the worst of the severe weather has passed Sydney.
The Bureau of Meteorology on Saturday predicted wind gusts exceeding 90km/h for the Illawarra, parts of the South Coast, the Hunter, Northern Tablelands, Southern Tablelands, eastern parts of the Central Tablelands and the Snowy Mountains regions.
From Saturday evening, inland areas of the Mid North Coast and Northern Rivers were also forecast to be affected.
A severe weather warning for damaging winds was cancelled for Sydney, however a strong wind warning remains in place for Sydney's closed waters and the Byron and Coffs coast.
Gale warnings are in place along the Macquarie, Hunter, Sydney, Illawarra, Batemans and Eden coast.
Hazardous surf is also predicted for these regions as well as the Coffs coast.
The vigorous westerly to southwesterly winds will be beneficial in one respect - providing a tailwind for about 75,000 runners and walkers participating in Sydney's City2Surf fun run on Sunday.
The bureau says the last of a series of cold fronts sweeping across the state will clear on early Monday.
Winds topped 113km/h on the South Coast's Montague Island on Friday while triple-digit gust speeds was also recorded at Bellambi on Saturday.
While there was minimal disruption at Sydney Airport, passengers experienced average delays of 45 minutes at the international terminal and 30 minutes at domestic terminals.
There were 10 cancellations across the day at domestic terminals, a Sydney Airport spokesman told AAP.
The airport is encouraging passengers to check with their airline about the status of their flight.
The NSW SES has received some 1167 requests for help since the weather event began, with a lot of these spread over the south-eastern half of the state especially the Blue Mountains.
SES members are working with police and the Rural Fire Service in this area to prepare for snow overnight and into Sunday, a NSW SES spokeswoman told AAP.
Teams in 4WD's are patrolling the Great Western Highway with first aid and emergency supplies and have set up refuge stations along the highway.
Motorists are encouraged to park their cars undercover away from trees, stay away from fallen power lines, check for road closures, to drive safe especially around the Blue Mountains and watch out for black ice if travelling up to the snow fields.
Police are urging motorists to drive with extreme caution after snow-affected roads caused multiple collisions near Jindabyne.
One incident involved a police car and three other vehicles, travelling at about 30km/h on Friday.
The three cars attempted to stop but collided after sliding on the roads along Alpine way.
There were also about eight other vehicles that lost control along the road and became involved in the incident.
Another five managed to avoid the collision but became stuck in snow on the side of the road.
Snow and ice continue to affect roads in the Blue Mountains, including Jenolan Caves Rd which is closed between Duckmaloi Rd and Jenolan Caves, and roads in and around Oberon.
In the state's south, snow and ice are affecting roads in Thredbo, the Snowy Mountains Highway area, and the Kosciuszko National Park.
The Great Western Highway between Mount Victoria and Lithgow remains open.
