Power is out in multiple towns, and repairs could take some time in remote areas.
Police said more than 1000 people were without electricity at one point on Friday, but the Ergon Energy outage map showed that figure had dropped significantly by 2pm.
Cooktown, Lockhart River, Coen, Hope Vale, Ayton, Rossville, Bloomfield and Wujal Wujal were among the impacted towns.
Cairns District Disaster Co-ordinator Kevin Fitzgibbon said communities, particularly on the west coast of the peninsula, could be impacted for hours more.
“Those communities need to remain vigilant,” he said.
“The system still is a powerful system.”
