International and domestic flights were delayed by an average of 90 minutes and more than 20 flights were cancelled at the airport. The Federal Government gave special permission for some flights to leave the airport after the 11pm curfew.

Most out-going flights, however, were left without a take-off time as incoming planes needed to land. At midnight, a number of flights were turned back from the tarmac to the terminal.

Airport staff will face a backlog of passengers and flights on Friday.

A severe thunderstorm warning was issued for parts of NSW, but was cancelled in the early hours of Friday morning. The Bureau of Meteorology expects intense storms to redevelop on Friday afternoon.

There is currently a marine wind warning in place for Sydney Closed Waters, Hunter Coast, Sydney Coast, Illawarra Coast and Batemans Coast.

According to the NSW Bureau of Meteorology, storms will continue on Friday and into the weekend.

"It still looks like there will be lingering showers for the next few days and into the weekend possibly," Bureau of Meteorology forecaster Chau Zhi-weng told 10 daily.

The SES is urging people to stay off the roads and change their travel plans before the rain hits. An SES spokesperson told 10 daily flood rescues are dangerous procedures and such situations can be avoided by people staying off the roads.
