Latest on the Port Hills fire: Thermal imaging shows continued reduction in hot spots

09 Mar 2017

Helicopter thermal imaging over the fire ground this morning shows a continuing reduction in hot spots.

  • Some thermal activity is still occurring in the Adventure Park, forestry plantations and some other locations, but the majority of the fire area is now clear of hot spots.
  • Seven fire crews are continuing to work on damping down and digging out hot spots today.
  • Six North Island fire crews will complete their deployment on Friday. Control of the fire will then revert to local crews who will monitor and patrol the fire ground over the weekend. 
  • Members of the public are reminded that the fire area remains hazardous. People should stay well away from the fire ground, and observe all closures of tracks and access points.
  • Anyone observing smoke or flames in and around the fire area should immediately call 111.
  • A prohibited fire season remains in place in Christchurch and Selwyn, including a ban on stubble burning.

Port Hills fire update: Monday, March 6, 4.30pm

The fire area has been re-evaluated based on the most recent aerial imaging, which has provided a greater level of detail on the burnt area. The new estimate of the fire area is 1645 hectares with a perimeter of 51 kilometres.

Predicted rain unlikely to cause significant issues

The weather forecast shows there will be rain tomorrow and it is believed the amount predicted to fall will not cause any significant issue due to rock fall, flooding or sediment runoff. Christchurch City Council’s land drainage team is monitoring the situation and will investigate options to mitigate these risks from future heavy rainfall events and the onset of winter.

Skips and rubbish collection

People tidying up debris from the fire can make use of skips placed at No. 323, 338 (2 skips), 351 and 353 Worsleys Road. These skips are being monitored and emptied as required. At locations where there are two skips, it would be helpful if people could put green waste in one and rubbish in the other. This will reduce the cost of disposal at landfill.

This will continue until further notice.

Kerbside collections are operating as usual where collection trucks can gain access.

Restrictions on Dyers Pass Road

We are monitoring the need for restrictions on movement along Dyers Pass Road and hope to be able to further relax these soon.
Parks staff working with firefighters to restore access

Christchurch City Council Parks staff are working closely with fire management to enable wider access to park areas.

It is hoped greater access to Victoria Park and Sugarloaf may be possible soon as long as it does not interfere with ongoing firefighting and hazard reduction. Parks staff thank the public for their continued support and understanding of the limited access throughout the fire effort and look forward to seeing people enjoying the areas again shortly.

Port Hills fire update: Saturday, March 4, 2pm

Fire incident controller Rob Hands says the 35.1km perimeter is now fully contained and controlled, with bare earth or blacked-out ground for at least 50 metres on both sides of the perimeter.

Thermal imaging has indicated a substantial reduction in underground hot spots within the 1819 hectare fire area, with spots remaining in only a few  areas.

Rob Hands says fire crews will continue to work on damping down and digging out hot spots during the day, but the reduction in thermal activity means there is no need to maintain overnight monitoring patrols.

“The public can be reassured that we continue to have firefighting resources on standby and ready to respond should any flare-ups occur. If anyone does see flames or fire activity overnight, they should ring 111 immediately.”

Port Hills fire update: Friday 3 March 10am

Thermal imaging undertaken early this morning continues to show a significant decrease in hot spots across the fire area, with major reductions in many locations including the area above Dyers Pass Road, Hoon Hay Valley, and parts of Worsleys Road and Marley’s Hill.

Hot spots are still being identified in other sites, including areas of pine plantation. This pattern is likely to continue for some weeks, as it is common for hot spots to lie dormant underground.

Rural fire incident controller Rob Hands says the majority of the fire ground is looking clear of thermal activity. “We’re definitely winning the war – these results show a major reduction in hot spots from previous scans,” he says. “But there’s a lot of work still to be done and crews will remain active on the ground for some time to come, dealing with the remaining hot spots and making the area safe.”

Weather

A change from north-east to north-west conditions is forecast form late morning today, with temperatures in the high 20s and winds of 20 to 40 km/h, gusting up to 60 km/h. These conditions are expected to remain until late evening when a change towards the south is expected, with a chance of light rain or showers overnight.

The north-west conditions today mean there is a heightened risk of flare-ups occurring and spreading within the fire area.

Rob Hands says fire authorities have been planning for several days for the conditions. Additional fire crews and observers are being stationed around the fire area today to monitor and provide an immediate response to any flare-ups. Helicopters are also on standby. Additional tankers, a portable dipping dam and other water sources are in place to provide water if required.

“We hope nothing untoward occurs today, but we’re confident we have the plans and people in place ready to respond should any flare-ups or breakouts occur.

“We do continue to urge people in the area to be vigilant and to avoid any activities that might contribute to the fire risk.”

Port Hills Fire Update #2: Wednesday, 1 March 4.30pm

State of Emergency ends

  • The state of local emergency covering Christchurch City and Selwyn District will expire at 6pm today.

Fire Update

  • Rural fire crews have been sent to Hanmer this afternoon to assist with the fires burning in this area. However 17 crews remain on site at the Port Hills fire perimeter, continuing to identify and extinguish hotspots. 
  • Thermal imaging from helicopters and drones continues to show a reduction in fire activity in areas where fire crews have been working to reduce hotspots. 
  • Fire crews have also been walking the fire ground area and will continue to do this. Particular focus will be forested areas where drone thermal imaging may not be fully accurate due to the tree cover. Fire crews are using hand held thermal imaging cameras to identify hotspots requiring extinguishing.

Friday weather forecast

  • In preparation for forecast warm and strong Nor’ West conditions on Friday, several portable dams will be available in case hotspots flare up and require attention. Fire crews will also be placed strategically in the fire zone.
  • Fire operations feel confident they will be able to be quickly extinguish any minor flare ups that may happen as a result of Friday’s weather conditions. Fire behaviour modelling has been undertaken to identify areas of potential fire escape. Priority areas near unburnt vegetation are being enhanced to create wider fire break buffer zones. 
  • Given the weather forecast for Friday, residents within the fire perimeter will need to continue to be on alert and ready to leave the area if needed.

Dog Parks

  • The dog exercise areas in Victoria Park and Halswell Quarry are currently closed. However there are a range of other dog parks available throughout the city that you may wish to visit.

Property access

All residents now have access to their property with the last two property owners at the top of Worsleys Road gaining access this morning.

Conservation donations

The Port Hills fires have seriously impacted the ecology of the Port Hills. Many members of the public are already offering generous donations to assist with the restoration of these important conservation areas so the Port Hills Fire Restoration Fund (external link) has been established.

This is a collaborative effort between Christchurch City Council, Selwyn District Council, government agencies, conservation groups, and the public support will aid the recovery efforts on publicly owned conservation land and private land with important ecological values.

Water Conservation

There has been heavy demand on the water supply network as a result of the firefighting response and some damage to water pipes in the area.

Civil Defence is asking people in the Port Hills area to conserve water as much as possible over the next week while water levels in the reservoirs are restored

Port Hills Fire Update #1: Tuesday 28 February 10.15am

Fire Update

Hotspots are still being found in a number of areas, but there has been an overall reduction of these across the fire area. About 20 fire crews will be working in the Port Hills today.

99 percent of the fire perimeter is controlled with at least a 10 metre break between the edge of the fire zone and vegetation.

Welfare

A reminder that GP visits for people in affected areas will be free for the next two months. The offer period covers the two months from 13 February 2017, the day the fire started.

Civil Defence payments are available if the fires have had a serious impact on you or your family. For further assistance visit this website or call 0800 559 009.

It is normal to feel anxious or stressed during abnormal events. Talking to someone can help and online tips are available.

Dyers Pass Road

There are a large number of burnt and unstable trees which are at risk of falling on the road. Civil Defence are prioritising the work to get the road open but some restrictions are likely to remain once it is open. Treetech are currently working on the most dangerous trees.

Contractors are also working to repair damaged marker posts and barriers.


Port Hills Fire Update #3: Monday 27 February 4.45pm

Fire update

Overnight crews will continue to monitor and patrol the fire in the Port Hills. Weather permitting, drones will be flying overnight to undertake thermal imaging and to support ground crews damping down hot spots. Around 20 fire crews will be operating tomorrow.

Welfare

If you know of anyone in the affected area who hasn’t registered or you are concerned about, please encourage them to register online or through the Council’s Customer Contact Centre on 941 8999 or 0800 800 169.

Port Hills Fire Update #2: Monday 27 February 2.55pm

Fire authorities describe the 35km perimeter of the fire area as now almost fully controlled. Controlled is defined as bare earth or blacked out ground for at least 10 metres.

• Yesterday and overnight 12mm of rain fell at the top of fire area, with around 5mm recorded lower down. Fire operations incident controller Mike Grant says the rainfall has helped reduce thermal activity and surface level hot spots, but had little effect on hot spots burning underground. There has also been some rock fall overnight on Dyers Pass Road as a result of the rain.

• Active hot spots are continuing to be seen – and this is likely to continue for another week or more. Fire crews are targeting hot spots in priority areas, including any located near unburnt vegetation and residential areas.

• Geotech assessments are being undertaken today in the Early Valley Road area to check on potential rockfall hazards.

Weather

Fire incident controller Mike Grant says firefighters are closely monitoring weather forecasts but do not anticipate any adverse weather impacts in the coming days.

Forecasts for the next 48 hours show relatively stable conditions with predominantly north-easterly winds, average wind speeds up to 24 km/h, and moderate temperatures ranging from about 12 to 19 degrees. Relative humidity levels also remain high at around 60 to 70%. No significant rain is forecast.

“These conditions are relatively benign, and as long as we can avoid hot, dry, blustery north-west winds, we can be confident of making good progress with our fire suppression efforts.

“We are continually monitoring forecasts and conditions on the ground, and we have the capacity to quickly ramp up our readiness should conditions change.”

Port Hills Fire Update #1 Monday, February 27, 10.20am

We are into day 15 of fire operations and currently have 22 crews on the ground, with 150 firefighters from around New Zealand. Thermal imaging from drones is helping to identify focus areas for crews on the ground. Firefighting activity has also identified new hotspots so operations are likely to continue for several weeks.

We are aware of some public concern about a hotspot in the Christchurch Adventure Park and you may note fire crews monitoring this overnight.

Dyers Pass Road

A decision has not been made about reopening Dyers Pass Road at this point in time. There has been some rock fall on the road overnight as a result of the rain. While it was mostly smaller sized material we need to understand the scale, cause and, if necessary, put measures in place to manage any further rock fall events. Re-opening the road remains a priority for us but it is important that we have an understanding of all risks before this occurs. 


Port Hills Fire Public Update #5 Sunday 26 February – 4.50pm

Fire crews

Overnight crews will continue to monitor and patrol the fire in the Port Hills. 

Weather permitting, drones will be flying overnight to undertake thermal imaging that will support ground crews damping down hot spots.

Tomorrow, firefighters plan to focus on eliminating hotspots in priority locations including the Early Valley Road area and the Summit Road. A large number of hotspots remain.

Dyers Pass Road cordons

Completing the work needed to reopen Dyers Pass Road is a top priority, as we recognise the significance of this key access route. It is still too early to say when the road will reopen but good progress is being made and there will be more updates tomorrow.

The condition of the road is good overall and edge markers were being replaced this afternoon. A geotechnical assessment of scattered rocks above the road has been completed. The remaining damage to guard rails and trees will be addressed tomorrow. We also expect the power cables will be checked and temporary speed limit signs installed.

Water conservation

We’re still asking people in the Port Hills area to continue to conserve water as much as possible over the next week while water levels in the reservoirs are restored. While today’s rain is helpful, there has been heavy demand on the water supply network from the firefighting response and some damage to water pipes in the area. 

Next update

Unless there is a significant development overnight this will be the last update until tomorrow morning at 9am.

Overnight crews will continue to monitor and patrol the fire in the Port Hills, both on the ground and in the air.

Port Hills Fire Public Update #4 Sunday 26 February – 3.20pm

Dyers Pass Road cordons

The team reviewing the condition of Dyers Pass Road this afternoon has reported back.

The condition of the road is good overall but almost all posts and guard rails have melted or been burnt and will need repairing or replacing. One power pole is damaged and some trees need removing. A geotechnical assessment of scattered rocks above the road is also needed.

We plan to complete this work as rapidly as possible, as reopening this key route is a high priority. We are getting a lot of queries about when Dyers Pass Road will open to the public and recognise the significance of this road. We will update you if the cordon situation changes.

Other cordons

There are 11 cordons in total. While cordons at Worsleys Road, Kennedys Bush Road, Hoon Hay Valley Road and Dyers Pass Road have been relaxed, this is for residents only. There is still no access for members of the public. Access for tradespeople to repair damaged houses is being arranged.

Current map of hotspots from the Port Hills fires Cordons are also being maintained at the entrance to Halswell Quarry during air operations to ensure public safety.

We are reminding people to resist the temptation to come and have a look around the area, this includes mountain bikers and runners. The area remains an operational fire zone with cordons still in place. Fire behaviour modelling indicates the chance of another outbreak is low but if it did happen, significant damage could still occur.

Fire crews 

A current priority for fire authorities is detailed mapping of unburnt vegetation within the perimeter of the fire. This 

will help fire crews to strengthen fire breaks around these areas and reduce the risk of new outbreaks. View the latest map of hotspots here [JPG, 1 MB]

A total of 25 fire crews from all over the country are working today, with about 150 firefighters on the ground. 

Port Hills Fire Public Update #3 Sunday 26 February – 1.50pm

Dyers Pass Road Cordons

A team is out the field this afternoon reviewing the Dyers Pass Road cordons, as reopening this key route is a high priority. We are getting a lot of queries about when Dyers Pass Road will open to the public and recognise the significance of this road. We will update you if the cordon situation changes.

At this stage three hard cordons remain on Dyers Pass Road. One is at the bottom where it meets Governors Bay Road, however residents who live on the section up to the hairpin bend about halfway up to the Sign of the Kiwi are permitted access to their properties. Dyers Pass Road is closed from this hairpin bend to the entrance of Victoria Park due to the fire risk and safety issues.

Other cordons

There are 11 cordons in total. While cordons at Worsleys Road, Kennedys Bush Road, Hoon Hay Valley Road and Dyers Pass Road have been relaxed, this is for residents only. There is still no access for members of the public. Access for tradespeople to repair damaged houses is being arranged.

Cordons are also being maintained at the entrance to Halswell Quarry during air operations to ensure public safety. 

We are reminding people to resist the temptation to come and have a look around the area, this includes mountain bikers and runners. The area remains an operational fire zone with cordons still in place. 

Fire behaviour modelling indicates the chance of another outbreak is low but if it did happen, significant damage could still occur. 

Fire crews 

A total of 25 fire crews, with around 150 firefighters on the ground.

An infrared scan from the air this morning showed continuing deep-seated activity across the area. There is a continuing overall reduction in hot spots – but we are still seeing a number of areas where hot spots remain. The crews are focusing on these. Drones are being used during nightshifts and early mornings for this thermal imaging. 

Heavy machinery is now being used for the ongoing removal of dangerous trees.

Weather

High humidity and lower temperatures are helping with suppressing the fire, and the today’s rain is welcome.

Cordon access – residents only

Firefighting operations will continue on the Port Hills until the incident management team is confident the fire is fully extinguished. The area is still an active fire zone.While cordons at Worsleys Road, Kennedys Bush Road, Hoon Hay Valley Road and Dyers Pass Road have been relaxed, this is for residents only. There is still no access for members of the public. 

Civil Defence Controller Malcolm Johnston says, “We’re appealing to the public to resist the temptation to come up for a look. Residents in these areas do not want rubberneckers, this includes mountain bikers and runners. There is also a significant safety issue, it is simply not safe for the general public to enter.” 

There are still many areas of the city where people can safely cycle, walk or walk their dogs. View the current status of walking tracks and cycling tracks.

Port Hills Fire Public Update #2 Saturday 25 February – 1.30pm

Drones invaluable

Following on from this morning’s update about drones, check out this footage (external link) of Dave Herries, Operations Manager talking about aerial infra-red and thermal imaging.

Walking and cycling tracks

Halswell Quarry remains closed to the public as it continues to be used as a staging area for firefighting operations. Tracks around Huntsbury, Bowenvale and into Victoria Park also remain closed. See full list of track closures here.

Please cooperate with these temporary closures to enable emergency services to get on with the fire response unhindered.

Update #1 Saturday 25 February 10am

Fire update

No significant incidents or flare-ups were reported overnight.

Infra-red and thermal imaging drones are being used during the night and early mornings to check hot-spots. Darrin Woods, Principal Rural Fire Officer says, “I can’t understate the value of this technology. Drone footage and the thermal maps enable fire crews to directly target the hot-spots in areas that have been scanned.

Twenty crews will continue to work today on strengthening the fire containment lines with heavy machinery, supported by helicopters and ground operations.

Dangerous trees will continue to be removed throughout the day.

A State of Emergency is still in place over both Christchurch and Selwyn and will remain in place as long as necessary.

Cordons

<>The cordons at Worsleys Road, Kennedys Bush Road and Hoon Hay Valley Road, have been relaxed for residents only. There is still no access for members of the public. Rural fire has deemed that this is still an operational fire area and as such public safety remains a priority and access must remain restricted.

Three hard cordons remain on Dyers Pass Road. One is at the bottom where it meets Governors Bay Road, however residents who live on the section up to the hairpin bend about halfway up to the Sign of the Kiwi are permitted access to their properties.

Dyers Pass Road is closed from this hairpin bend to the entrance of Victoria Park due to the fire risk and safety issues. Preparations are underway to have the road open as soon as possible after the risk mitigation work is completed.

Walking and cycling tracks

A reminder that Rapaki, Mt Vernon Shared Use and Mt Vernon Farm tracks have reopened. However, a number of tracks remain closed. Visit the Council’s Parks web page for more information.

Recovery Managers named

Al Lawn and Murray Sinclair have been named as the managers to lead the Port Hills fire recovery in Selwyn district and Christchurch city respectively.

Christchurch Mayor Lianne Dalziel, as chair of the Canterbury CDEM Group Joint Committee, announced the appointments today.

“I am delighted that Al Lawn and Murray Sinclair have been appointed to the Recovery Manager roles and will lead the transition going forward. Both Al and Murray have extensive experience working in Civil Defence and I am confident they will effectively manage the recovery phase.”

More information on the Recovery Managers.

Update #4 Friday 24 February 5.15pm

Water Conservation

There has been heavy demand on the water supply network as a result of the firefighting response and some damage to water pipes in the area.

Civil Defence is asking people in the Port Hills area to conserve water as much as possible over the next week while water levels in the reservoirs are restored.

Dyers Pass Road

While Dyers Pass Road remains closed by emergency services, due to the fire risk, preparations are underway to have the road open as soon as possible

An assessment team has been into the cordon to review the damage and the good news is the road surface is physically safe, however a number of other safety issues must be addressed before the road is safe to reopen to the public. These include damaged signage and barriers, the risk of rock fall and the danger posed by damaged trees.

Preparations to address these safety issues are currently underway, however contractors will not be allowed into the cordon to carry out this work until the fire risk has been eliminated. A reopening time and date cannot be made until this happens.

It is appreciated this closure is very frustrating for the surrounding communities, but addressing all safety issues must be the priority.

Update #3 Friday 24 February 2.30pm

Aerial video showing Port Hills fire damage

Private water supply

Christchurch City Council is monitoring the main water supply for residents in affected areas. Residents that have a private water supply will need to manage this themselves. Any residents with concerns about possible contamination in their fresh water supply may wish to follow these helpful tips (external link) .

Port Hills parks

  • View of Kennedys BushVictoria Park: parts of Victoria Park including the dog exercise area, playground and picnic area, information centre and lower Harry Ell track are unaffected by the fire. However firefighting operations and assessments are still being carried out in these areas so until this work is completed public access is prohibited.
  • Halswell Quarry remains closed to the public as it continues to be used as a staging area for firefighting operations.
  • Tracks around Huntsbury, Bowenvale and into Victoria Park remain closed. See the full list of track closures here.
  • While areas of Marleys Hill and Mount Ada were significantly burnt in the fire, large sections of Kennedys Bush remain intact.
  • The future regeneration of the Port Hills area will be considered as part of the wider recovery plan for the area. 

Update #2 Friday 24 February 11.30am

Fire Situation

Principal Rural Fire Officer Darrin Woods said the area was still an active fire zone with new hot spots being identified.

“As long as hot spots remain in the Port Hills we will have a presence and this could be for some time, possibly up to four weeks unless there is a significant change in the weather. With ongoing firefighting activities in this area it is likely some access restrictions will remain in place.”

No significant incidents or flare-ups were reported overnight.

Extensive thermal imaging was carried out overnight, showing a continuing overall reduction in hotspots from yesterday. Significant reductions in hotspots have been noted in the Early Valley Road area, Hoon Hay Valley and Worsleys roads, above Dyers Pass Road, in the Adventure Park and in the area above Governors Bay. However hotspot activity is continuing to be seen in most areas.

Drones will be operating today, carrying out mapping and photography of the fire area, and assisting fire crews on the ground to identify hotspots.

Fire crews and support staff continue to be rotated throughout the operation to ensure all staff remain fresh and rested.

Update #1 Friday 24 February 9am

Residents meetings

There was good attendance at all three meetings – 23 residents at Hoon Hay Valley, 75-80 at Worsleys Road and 95-100 at Kennedys Bush. 

The meetings gave residents the latest information on the status of and risk from the fire in their area and where to seek additional help if needed. Residents also had the opportunity to ask questions. 

Fire situation

  • 95% of the fire perimeter area is now considered to be controlled. Controlled is defined as bare earth or blacked out ground for at least 10 metres. 
  • Twenty crews are continuing to work today on strengthening containment lines with heavy machinery, supported by helicopters and ground crew operations 
  • Drones are continuing to be used during nights and early mornings to carry out thermal imaging.

Cordons

The cordons at Worsleys Road, Kennedys Bush Rd and Hoon Hay Valley Rd, have been relaxed for residents only. There is still no access for members of the public. Rural fire has deemed that this is still an operational fire area and as such public safety remains a priority and access must remain restricted. 

Three hard cordons remain on Dyers Pass Road. One is at the bottom where it meets Governors Bay Road, however residents who live on the section up to the hairpin bend about halfway up to the Sign of the Kiwi are permitted access to their properties.

Dyers Pass Road is closed from this hairpin bend to the entrance of Victoria Park. Public safety is a primary reason for the closure.

There has been considerable damage to not only the road infrastructure (ie burnt out guard rails) but also to the surrounding terrain above the road and it is considered there is an increased risk of rock-fall. This is due to the exposure and/or possible movement of rocks due to sluicing/drying of the ground. Also, partly burnt trees have been destabilised and pose a risk of falling onto the road. Civil Defence are working with Geo Technical/Structural Engineers and contractors to stabilise the rocks and trees and make the road safe.

At this stage there is no confirmed timeframe for the removal of these cordons.


Update #5 Thursday 7pm February 23

Fire situation

  • Overnight crews will continue to monitor and patrol the fire area.
  • Drones will be flying again overnight to undertake detailed mapping and thermal imaging. The drones provide accurate information about hotspot locations which is then given to fire crews to allow them to accurately identify which areas should be targeted to reduce fire activity. Drones are now also being used during daylight hours to support ground crews, providing visual access into difficult areas and helping to direct firefighters to hot spots. For safety reasons, the drones are not used over inhabited properties. 
  • Helicopter thermal imaging will recommence from first light tomorrow to continue identifying hot spots across the fire area.
    •  90% of the fire perimeter area is now considered to be controlled. Controlled is defined as bare earth or blacked out ground for at least 10 metres.
  • About 100 people have worked in the fire area today, in both land-based and aerial operations.
  • Fire crews are also working to identify any unburnt vegetation within the fire area and to reduce the fire risk associated with these areas by creating fire breaks or removing vegetation.

Smoke

  • Smoke remains an issue, but will continue to reduce as the hot spots are cooled.
  • If you are troubled by smoke or dust close your windows and doors, and avoid going outside until it abates.
  • Anyone experiencing health issues relating to smoke or dust should phone their own GP team.
  • A reminder that GP visits for people in affected areas will be free for the next two months – The offer period covers the 2 months from 13 February 2017, the day the fire started.

Residents welfare

  • The Welfare team are undertaking to contact all affected residents by phone to ascertain welfare needs and property condition.

Recovery

  • Initial recovery planning is underway and in the next few days both Christchurch City Council and Selwyn District Council will be announcing Recovery Managers to lead the recovery planning. Further information will follow once these appointments have been made.

Update #4 Thursday 2.30pm February 23

Free GP visits

Free GP visits are being offered to people affected by the Port Hills fires, at the discretion of their General Practice team. This includes people who worked on or are still working on fire control and recovery operations.

The offer period covers the two months from 13 February 2017, the day the fire started.

Update #3 Thursday 1:00pm February 23

Fire operations

Fire services advise that 90% of the fire perimeter area is now considered to be controlled. Controlled is defined as bare earth or blacked out ground for at least 10 metres.
About 100 people are working in the fire area today, in both land-based and aerial operations. While most of the fire perimeter area is defined as controlled, within this area there are many hotspots which could potentially flare up under some weather conditions and these are the focus of much of the fire operation.

Drones continue to be used to assist with the fire operation. They were used overnight to gather thermal and infrared hotspot imaging information. The drones provide accurate information about hotspot locations which was given to fire crews to allow them to accurately identify which areas should be targeted to reduce fire activity. Fire services are also looking at whether the drones may be used during the daytime. For safety reasons, the drones are not used overhead inhabited properties.
Thermal imaging continues to show a steady reduction in hot spots across large parts of the fire area, as a result of work by fire crews on the ground. However there are still a number of locations with where hot spots are continuing to be detected. New hotspots are continuing to be mapped and identified.
Fire crews are also working to identify any unburnt vegetation within the fire area and to reduce the fire risk associated with these areas by creating fire breaks or removing vegetation.

Smoke and dust

Fire suppression activities may generate dust or smoke. Smoke concentrations are forecast to continue to reduce as the fire hot spots are cooled. Concentrations will be high near and above the fire ground and may spread to neighbourhoods closest to the fire. In higher winds dust may pick up from the fire ground and get carried off the hill. Today, the projected trajectory for dust and/or smoke is towards the western suburbs of the city with highest concentrations at the base of the hill.
Health effects from short term exposure to smoke the will be little more than a nuisance. It may irritate the eyes, nose throat or airways. People with pre-existing respiratory illness or heart disease may experience a worsening or recurrence of their condition. If you are troubled by smoke or dust close your windows and doors, and avoid going outside until it abates.
Anyone experiencing health issues relating to smoke or dust should phone their own GP team. After hours a nurse will answer the phone and can advise you what to do or where to go.

Update #2 Thursday 11:30am February 23

Dyers Pass Rd

Cordons

Residents of the Governors Bay area have inquired about the Dyers Pass Rd cordon.
Hazard assessment work is continuing on the slopes above this road, including for the risk that large rocks and trees could fall on the road.

There are still significant hotspots in the Marleys Hill area that are under active fire management.The condition of the road is also being assessed.We understand the frustration this road closure is causing and crews are working to open the road as soon as possible. Unfortunately, at this stage we are unable to give residents a timeframe for its reopening.

Livestock

There have been issues with wandering stock on some roads in and near the fire zone. Wandering stock is a significant hazard to road users. If you see wandering livestock please call the police on 111.

Aerial operations

As the fire becomes more manageable air operations are being reduced. Today there will be four aircraft operating. Drones are continuing to be used for thermal imaging to locate hotspots that still pose a risk of flare-up.Please remember, the fire area is a no-fly zone. This rule applies to all aircraft not involved in the firefighting effort, including private drones.
