Sydney appears to have dodged the wild weather that has pummelled parts of Canberra and the Blue Mountains with hail stones.

The Bureau of Meteorology issued a warning on Friday afternoon of severe thunderstorms in parts of the Blue Mountains and Hawkesbury areas west of Sydney.

The bureau said large hailstones and damaging winds were likely as the thunderstorms moved south.

In Canberra, a library was closed as a result of the storm, while the ACT State Emergency Service had received 56 calls for assistance related to flooding, hail damage and fallen trees by 4.20pm.
