A severe weather warning is in place for the Coast and Highlands for heavy rain, damaging winds and hail.
The conditions are being caused by a low pressure system over inland New South Wales which is drawing humid air across eastern parts of the state.
People are being asked to keep their cars under cover, secure any loose items around the house and stay away from fallen powerlines.
The next warning will be issued at 5:10pm.
