Severe thunderstorms tore through parts of New South Wales on Friday, September 7, leaving areas across Sydney covered with a blanket of hailstones.

The Bureau of Meteorology issued severe thunderstorm warnings and warned of heavy rain, flash flooding and large hailstones in a number of regions across the state.

Lightning strikes at a rate of 1,000 per hour were recorded in the 50 kilometre radius around Sydney causing delays at the airport, and flash flooding caused disruptions to the rail network.
