A fire weather warning is in effect for the entire north coast today.
Local firefighters are on alert, with high temperatures and north-west winds raising concerns.
A total fire ban came into effect at midnight and will last for at least 24 hours.
Superintendent Michael Brett, from the Rural Fire Service, says an incident south of Casino yesterday afternoon highlighted the danger posed by the conditions.
"We picked up a new fire late yesterday out in the Rappville area," he said.
"We had a hazard reduction out there the landholder had, and under the conditions it got away and jumped a couple of roads and we had to put aircraft and some machinery in there last night just to try and catch that.
"We'll have crews out there again today just patrolling and monitoring that to make sure it does stay behind its containment lines."
