After a night of high winds and rain, Canberrans woke up on Sunday to more wet weather, which caused flash flooding through the morning.

Sixty millimetres of rain were recorded in the space of an hour at Sullivan's creek, just off Lake Burley Griffin, according to the Bureau of Meteorology (BOM).

Just before 1:30pm, BOM cancelled the severe thunderstorm warning in place for the ACT, but warned Port Macquarie, Taree, Orange, Bathurst, Walgett and Dubbo could experience flash floods.
