Authorities are reminding the public to be prepared, with strong winds and possibly snow forecast across the Barrington Tops for the next three days.

Access from Gloucester is currently closed, due to an unstable road in the Barrington Tops State Forest, which was damaged during rain in March last year.

Hunter Valley Police District Chief Inspector Guy Guiana says travellers need to take care.

“While access to the Barrington Tops from Scone is currently available, the unsealed road section is steep, narrow and winding, and ice and snow can make driving here extremely dangerous, even for 4WDs,” he said.

“With strong winds, there is also potential for trees and branches to fall, posing a direct risk to visitors, and possibly blocking access into and out of the area.”

Mobile phone reception can be spotty, so visitors are also being urged to check conditions and road closures ahead of time.

Conditions could change rapidly, including rain, snow, strong winds, and sub-zero temperatures.
