Huge hailstones batter parts of Sydney as a severe storm sweeps through

Sydney has again been battered by a summer storm with parts of the city pelted with hail.

Hail almost as big as a tennis ball fell in Prestons.

The Bureau of Meteorology warned of severe thunderstorms and heavy rainfall that could lead to flash flooding, destructive winds and "giant hailstones" on the east coast, stretching from Lismore in the north to Moruya Heads on the south coast.

Residents of Oran Park and Harrington Park in Sydney's west seemed to cop the brunt of the hail, with residents reporting hailstones the size of tennis balls and golf balls.

Suburbs across Sydney looked as though they had been blanketed by snow.
