Rainfall not enough to extinguish fires raging in northern NSW

Rain has eased conditions for firefighters but there is still plenty of work to be done to contain northern NSW bushfires ahead of a rise in temperatures in the coming days.

Firefighters are still working to contain northern NSW bushfires before temperatures rise in the coming days.

Busbys Flat and Drake fires continued to burn along with several other blazes on Saturday, after a horror week in which an elderly couple died and at least 55 homes were destroyed.

NSW Rural Fire Service spokesman James Morris said rain had eased conditions significantly, but it wasn't enough to extinguish the fires.

He said crews would keep working to contain them before temperatures and winds rise again in the coming week.

"We haven't had enough rain to really make a difference to the ground fuels, so they will dry out very quickly once we see some sunny and windy weather again," Mr Morris told AAP.

He said temperatures and winds were expected to increase from Tuesday.

The Busbys Flat fire, which authorities believe was deliberately lit, remained out of control on Saturday night, while the Drake blaze, which was started over a month ago by a lightning strike, was being controlled.

The latter fire claimed the lives of Bob Lindsay, 77, and his wife Gwen Hyde, 68.

Their bodies were found in their destroyed Coongbar home on Thursday some two days after fires roared through the region.
