Hail, lighting and flash flooding has sparked transport chaos across Sydney after a freak thunderstorm lashed the city.

The Bureau of Meteorology (BOM) issued a warning that thunder and lightning would hit on Friday late afternoon, with Gosford, Sydney, Wollongong, Orange, Katoomba and Parkes all under threat.

Travellers at Sydney airport were left frustrated by delays and cancellations after almost 50 flights were cancelled.

'Sydney's weather has thrown the airport into SO much chaos that there's security on the Qantas lounge door,' one traveller shared to Twitter.

'Sydney's Qantas club is filled to capacity while the airport is closed for who knows how long while this thunderstorm passes. #sydneyweather,' tweeted another.

Planes were stuck on the tarmac for up to two hours amid the havoc.

'Fun Qantas flight from Adelaide to Sydney. Board aircraft as per schedule and sit at gate for 30 mins before we're told to deboard. Flight takes off 75 mins later and now stuck on Sydney tarmac for 40 mins. Amazing how Oz airports can't deal with weather,' one flyer tweeted.

'Sydney airport was a disaster this afternoon! Just lucky to get out! Planes on the tarmac for 2 hours due to the weather!' shared another.

Weatherzone meteorologist Angus Mclean told Daily Mail Australia that Bankstown recorded 62mm in a one hour period between 5.30 and 6.30pm.

The suburb recorded a total 67mm of rain, well above the September monthly average of 44mm.

Bankstown also recorded its wettest day since June 2016 and its wettest September day in twelve years.

A ten-kilometre radius of the area was also hit by three and a half thousand lighting strikes throughout the evening.
