The east coast of New South Wales has been hit with a severe weather warning: winds are expected to reach more than 90 kilometres an hour in some parts of the city.

A low-pressure system drifting eastward from the south has caused Jetstar, Qantas and Virgin to cancel most domestic flights into and out of Sydney scheduled for today.

At the time of writing, at least 60 flights leaving Sydney have been cancelled and many more have been delayed, including from Melbourne, Brisbane and Adelaide into Sydney.

International flights in and out of Sydney airport are also being affected.

The Bureau of Meteorology has recorded damaging winds with an average of 60 to 70 kilometres an hour in the CBD and Mascot. This morning winds as high as 106 kilometres an hour were recorded at Sydney Harbour, reports the Sydney Morning Herald.

Travellers have been advised to check individual airlines for updates; the winds are likely to worsen throughout the day.

Weatherzone reports: “Today will be the windiest day of the year for much of the coast and ranges of New South Wales with potential to be the windiest day in more than two years in parts, including Sydney.

“Due to the single runway operation at Sydney Airport, Qantas has cancelled 12 services over the day and re-accommodated customers on the next available services,” a Qantas spokesperson told

Virgin Airlines has also cancelled and delayed many flights heading to all major cities. Departures as late as 7.30pm will not fly as experts from Weatherzone predict winds to continue through the night.

The Bureau of Metrology believes winds will ease in most areas – including the airport– by Saturday, but weather will persist along the coastal fringe until Saturday night.
