Taylor Swift jetted into Sydney on Monday ahead of her four-day concert run at Accor Stadium this week.

But Swifties are now worried the megastar, 34, may not even make it on stage thanks to the Harbour City’s extreme weather.

The Bureau of Meteorology has issued a severe thunderstorm warning for heavy rainfall, damaging winds and large hailstones for much of NSW on Friday and Saturday, placing a question mark above Swift’s first and second Sydney shows.

According to the Accor Stadium website, ‘events will go ahead rain, hail or shine’ unless the safety of patrons and the artist is at risk.

This leaves the potential for organisers to make last minute adjustments to Swift’s shows depending on the severity of the weather.

Concerned fans have taken to Reddit to speculate on whether these shows will be axed or postponed, with one writing: ‘Since it’s at Accor stadium and they have a rain policy, any chance it get’s cancelled if the weather’s bad.’

‘I can see a LOT of people freaking the f**k out if they do,’ the user added.

‘I’d say the only cancellation reason would be lightning. No one wants TayTay to die during an outdoor concert in Sydney!’ another wrote.

It’s at Accor, so it’s not fully under cover. She’s performed in the rain before so it would have to be very heavy rain and lightning for her to postpone. She’s only postponed two shows during this tour, I believe,’ someone else surmised.

Swift has already experienced setbacks thanks to Sydney’s stormy weather on Monday, after her private jet was delayed by up to 30 minutes as the pop star flew in from Melbourne.

Swift and her team were seen departing Melbourne at about midday on Monday, and landed safely in Sydney at 1.25pm.

If all goes to plan, she will play four sold-out shows from Friday to Monday, with 80,000 people attending each night.

Swift is believed to be staying at Crown’s presidential villa in Sydney’s Barangaroo while in town.

It comes amid rumours Swift is set to fly her NRL star beau Travis Kelce to Australia as she continues her Eras Tour.

On Tuesday, Swift’s private jet once again took to the skies on a flight bound for Honolulu, while the pop star stayed back in Sydney.

The flight from Sydney to Honolulu is usually around 10 hours on a commercial flight, however Swift’s luxurious Bombardier Global 6000 is designed to fly faster than a conventional aircraft.

Kelce was last spotted in Kansas City, but it is possible that he is planning to catch a flight to Hawaii to board his girlfriend’s private jet.

From there, he could fly back to Australia in time to watch Swift perform at Sydney’s Accor Stadium later this week.

Swift’s jet makes for a far more luxurious flight than Kelce would experience flying commercial, as the aircraft boasts a which a double bed and fine dining cabin.
