Hail has blanketed part of Sydney and the New South Wales Central Coast as severe storms moved across the Hunter region, the mid-north coast and other parts of New South Wales.

The Bureau of Meteorology has cancelled the severe thunderstorm warning for Sydney, Newcastle, Wollongong, and plains districts, but warnings remain in place for the mid-north coast, parts of the Hunter, and the central tablelands.

The State Emergency Service has received about 160 calls for help and said most calls were for leaking roofs and gutters.

The SES also said there had been isolated incidents of flash flooding.

Heavy rainfall hit Hornsby and Mona Vale, Berowra and Palm Beach in Sydney’s north and Northern Beaches.

In Sydney’s west, Blacktown and Baulkham Hills have received 30 millimetres of rain in 30 minutes and hail less than 2 centimetres in size were reported.

Areas affected on the Central Coast included Woy Woy, Umina, Kariong and Kilcare on the Central Coast.

As the storms moved in a north-easterly direction, Gosford, Terrigal, Bateau Bay, Erina, Budgewoi, Toukley, Wyong and Tuggerah on the Central Coast were expected to be inundated with heavy rainfall.

The BoM said the thunderstorm was likely to produce hail bigger than two centimetres in diameter.

Air Services Australia said in a tweet that the thunderstorm activity in Sydney had caused delays to flights.

Ausgrid said emergency crews was working to restore power to about 1,700 homes and businesses in Maitland and East Maitland.

In south-west Sydney, power has been restored to 1100 homes and businesses in parts of Bass Hill and Villawood after a tree fell on the electricity network.

Ausgrid said power was also out to 1300 customers in Killcare, Hardys Bay, Pretty Beach and Macmasters Beach on the Central Coast.
