Parts of Sydney were blanketed in hail on Tuesday as the nation’s leading weather forecaster issued a fresh warning for flash flooding and severe weather.

Hail pounded parts of Sydney and regional NSW across Tuesday.

Large storms across coastal areas of the state sparked warnings for flash flooding, damaging wind and large hailstones from the Bureau of Meteorology.

The warnings apply to people in the Hunter, metro, Southern Tablelands, Illawarra, Central Tablelands and South West Slopes regions.
