Keep up to date with the bushfire situation with our rolling coverage
The Rural Fire Service has described the battle to contain the current serious bushfire threat as a marathon and not a sprint.
Fires virtually ring the Port Macquarie-Hastings local government area.
RFS public liaison officer Paul McGrath urged residents in affected areas to be aware of the changing conditions.
He said high temperatures ensured exhausted fire fighters were kept on fire grounds where at least two fires had a high fire danger rating.
"When fires are at that level they are difficult to control," Mr McGrath said.
"The Gum Shrub and Hillville Road fires - both at emergency warning level - are both spotting up to four kilometres ahead of the fire front.
"Therefore we have advised residents in those areas to shelter in place, or to leave now which is their best option.
"When we put out an emergency warning, we need people to adhere to those warnings, enact their bushfire survival plan and follow information on the Fires Near Me app and constantly check the RFS website."
Mr McGrath said the biggest threats facing fire fighters and residents on Saturday November 9 were the Gum Scrub and Hillville Road fires.
He said due to the fire behaviour and activity these two fires will remain at emergency warning level. "But they are being reviewed," he added.
Crews will remain on the ground overnight although "at this time of the night we lose aircraft support".

"Crews are undertaking property protection and operational fire fighting procedures," he said.
Here is a rundown of some of the bushfires in the region.
Gum Scrub - An emergency warning is in place for this bushfire which is more than 800 hectares in size. It is out of control.
The fire is burning north of the Wilson River, in the Cooperabung and Telegraph Point area.
The fire has breached containment lines and crossed Red Hill Road.
It is burning towards the area of Sun Valley Road and Federation Way.
If you are in the area of Sun Valley Road and Federation Way, Cooperabung and your plan is leave, or you are not prepared, leave now towards Port Macquarie.
Stockyard flat - This bushfire is burning in the Stockyard Flat, Spur Trail, Yarrowitch, Oxley Wild River National Park area.
The fire is more than 62,000 hectares in size and is out of control. It is at watch and act level.
Mr McGrath said this fire is progressing in an easterly direction and is quite a large fire.
This fire started in the Walcha LGA and has now progressed into the Port Macquarie-Hastings.Paul McGrath
"This fire started in the Walcha LGA and has now progressed into the Port Macquarie-Hastings," he said.
"We are installing broad containment strategies and these are being implemented over the next few days.
"There are several options including heavy plant to clear containment lines and undertake forms of back burning throughout the different fire grounds.
"We will mainly do that to strengthen and consolidate our containment lines," he said.
Conditions on the fire ground have eased.
Crestwood Drive/Lindfield Park Road - There is internal burning and the winds from Friday night - which were very strong through Port Macquarie - which saw the closure of the Oxley Highway.
"The fire moved from the northern side of the Oxley Highway into the southern side," Mr McGrath said.
Crowdy Head - This fire escalated on Saturday and is at emergency warning level.
Mr McGrath said the bushfire is burning in the Crowdy Bay National Park due to a wind change from the east.
It has been dropped to watch and act due to the conditions of the fire's behaviour.
There was concern that the fire travelling east could impact the Pacific Highway and the North Coast railway line.
Mr McGrath said the fire is now listed as being controlled.
Crowdy Head Road is closed.
Diamond Head camping area is closed.
Kylies Beach is currently closed.
Mr McGrath praised the community - and in particular small business operators - for supporting volunteers fire fighters over the last few weeks.
"It has been a big ask over the last few months," he said.
"The community has been fantastic and we appreciate the support they are giving us as well.
"We also have support from many agencies including Forestry Corp, National Parks and Wildlife Service, Fire and Rescue NSW and RFS crews."
