Update on Port Hills fire – 11PM
Update on Port Hills fire – 11PM
NOTE: Unless
necessary, there will be no further updates until 8AM
tomorrow (Sunday)
Temporary resident access to cordon
zones
As a result of significant progress tonight in
assessing fire containment lines, residents will be
permitted temporary access to the cordoned zones between 9am
and 11am on Sunday 19 February.
Selwyn’s Emergency
Operations Centre will issue a confirmation of this managed
access at 8am. Weather conditions and the level of risk of
the fire to spread will be key considerations in the access
going ahead.
If confirmed, Police will manage access to
the zones and residents will need to register if they have
not already done so, either online, by calling the CCC Call
Centre at 941 8999, or at the cordon entry.
Access points
will be located at 305 Kennedys Bush and 51 Hoon Hay Valley
Road only.
Sign-in and compulsory briefing for Kennedys
Bush Road residents will happen at 8am for a 9am
entry.
Sign-in and compulsory briefing for Hoon Hay
Valley Road residents will happen at 9am for a 10am
entry.
Residents will be permitted access to retrieve
essential items only. The managed access will be restricted
to adult residents only.
Worsleys Road remains the most
at risk of fire spreading, and with a number of complex risk
factors, it is unsafe to enter. Options for access to
Worsleys Road properties will be re-assessed tomorrow
(Sunday).
Firefighting operation update
Firefighting
crews have made good progress in controlling the Port Hills
fire today; however, it is far from being put out.
Rural
and urban fire crews have done a good job of containing the
fire around the 29km perimeter, which is now about 68 per
cent controlled. This is defined as bare earth or
blacked-out ground for at least 10 metres.
Today 20 fire
crews have continued to create a 20-metre fire-break with
heavy machinery and by hand. Air operations also helped
ground crew who were identifying hotpots and putting them
out.
Three fixed-wing aircraft dropped about 60,000
litres of retardant today over a 1.5-kilometre line along
the perimeter of the fire area, between Kennedy’s Bush
Road and Hoon Hay Valley Road. Each aircraft made 10 drops
of 2,000 litres each. The line should be completed by
nightfall.
If weather conditions remain favourable,
another retardant drop will be made in the Marley’s Hill
area to strengthen the existing line around the Sugarloaf
communications aerial.
Risk of flare-ups high
Fire
behaviour specialist Nathan Keoghan says it is important to
remember that the fire is not out, and that there could
still be a few difficult days ahead.
Mr Keoghan says the
fire risk remains high. There is still a risk of flare-ups
that may ignite unburnt vegetation fuel inside the burnt
area, as well as outside the containment and control lines.
The ground temperature of hotspots in the fire area can
be anything between 100 and 500 degrees Celsius.
“The
3mm of rain over the last 24 hours has been helpful;
however, more is needed to reduce the risk of flare-ups.
About 50mm in one day, or 30mm over three consecutive days,
is needed to cool the extreme ground temperatures and lessen
the risk of unburnt fuel catching fire,” says Mr
Keoghan.
“Warm temperatures forecast with windy
conditions could change things very quickly. It would draw
any moisture from the ground in a few hours and could result
in flare-ups.”
Total fire ban remains in place
A
total fire ban remains in place for the Canterbury region.
This was put in place by the National Rural Fire Authority
last Thursday to free up resources for the firefighting
effort on the Port Hills.
As firefighting resources are
so stretched, there is limited capacity to respond to any
other events.
The Port Hills firefighting effort has
required a national multi-agency approach. Everyone involved
is focused on doing anything possible to control the fire,
remove threat and protect people’s lives and
homes.
