Police are investigating the cause of several fires across the Upper Hunter over the weekend.
The blazes ignited as we experienced those hotter-than-usual conditions for this time of the year.
A fire at The Common off Coal Road in Muswellbrook lit up the night sky again, one of several times fire crews have been called to the location in the past week or so.
Firefighters also attended an incident on Martindale Road at Denman on Saturday afternoon.
Further south a bushfire closed roads between Abermain and Cessnock.
