Efforts have begun to clear water, remove branches and debris and restore power to battered Sydney homes after dangerous thunderstorms bore down on the city overnight.

Parts of New South Wales were smashed by a furious storm cell on Thursday, bringing strong winds, giant hail and heavy rainfall.

A severe thunderstorm warning was issued for Sydney and the Illawarra district, as well as the greater Gosford, Wyong and Newcastle areas, before being cancelled around 2am on Friday.

The Bureau of Meteorology (BoM) still urged people to take care, with storms likely to develop again Friday afternoon.

The storm wreaked destruction in Sydney before moving north through Gosford, Wyong and Cessnock towards Newcastle in the early hours of Friday.

Parts of the northern beaches were without power on Thursday night as the fierce thunderstorm swept through. AusGrid said electricity had been cut to thousands of homes, mainly on Sydney’s north shore and the northern beaches.

By 11pm, 26,000 customers were still without power. AusGrid said emergency crews were working to restore power as quickly as possible.

The State Emergency Service has fielded hundreds of calls for assistance and said people should move cars under cover.

Authorities say roads, the rail network and Sydney Airport have also been impacted. Passengers at Sydney Airport were experiencing delays of up to about 90 minutes at the airport and 20 flights have been cancelled due to weather.

The Federal Government gave permission for some flights to leave Sydney Airport post the 11pm curfew, but many planes were stuck on the tarmac without a take-off slot, because so many planes still needed to land. At midnight, some were being turned back to the terminal.
