Looking forward / desiring for this thread to be very quiet
Post from one of our guys just recently, maybe this week, that this time last year he was on the way up to the north of NSW on first deployment of what has been a shitty 12 months. At least there's been much more rain this season so drought factor shouldn't be so bad!
Outlooks are actually for below-average fire danger along most of the East Cost until October.
But lookout Southwest WA.
First ping of the season
Terry Hills RFS doing a set of pretty aggressive hazard reduction burns on the Sydney northern beaches this weekend - 27 degrees today and a sea breeze.
Often have issues in Northern Beaches district with fuel moisture and local climate that prevent burns from being feasible. They have to account for the weather and fuel moisture
Heathcote Watch and Act. Hazard Reduction has spotted across the highway and taken off. LAT heading in for a drop.
Traffic heading home from down the coast heavily affected.
Looked at some of the details. Sounds like the traffic has been affected all day, due to crew safety for the burning, and now due to the increased activity. 7news helicopter live streaming
1 LAT drop completed. Birddog still over the fire, so expect another one
Second drop done. New paint scheme looks angry, particularly nose-on
Will be plenty of work tomorrow to get this contained.
It's quite gusty down here in Wollongong...
Given the wind and humidity forecast, WTF did RFS and NPWS conduct the burn Sat 10 Sept. Winds at nearest weather station (ANSTO) gusted upto 50klm. I sometimes wonder their thoughtfulness.
What was the forecast for yesterday?
Wow we are getting the full micky today, I was looking SE and wondering what this was. Looks like it's just Pyrocumulus no lightning for the 'nimbus 'to be added.
Another controlled burn lost. I'm not against controlled burning, but sooner or later somebody is going to have to step up and take responsibility for these things.

Introducing fire into the landscape is inherently risky, particularly as we head towards the warmer part of the year.
When implementing such activities, multiple controls are applied both in the planning and implementation stage, to reduce and manage the risk.
One of the main controls utilised is referred to as a ‘prescription’. A prescription is a set of conditions or parameters that provide limits or thresholds on whether an activity should proceed or not, based on expected fire behaviour.
A burn prescription often includes parameters such as fuel dryness, in addition to diurnal weather conditions peaks and troughs, such as temperature, humidity, wind direction and strength.
Choosing a prescription is a complex mix of the right ingredients - with flexibility applied by balancing and offsetting various conditions, which are highly variable.
An example of flexibility is burning when conditions are windy, but only if fuels are moist and the fuel load are light.
If fuels loads are high and conditions are dry, you need to be more cautious, particularly with lower humidity and changes in wind strength.
Another important component when introducing fire into the landscape, is how the fire is ignited. Lighting a line of fire will result in fire reaching its intensity and rate of spread quickly, where if multiple spots are introduced instead, it will spread slower.
Looking at recent events locally, there will be be community scrutiny surrounding the safe implementation of hazard reduction burning, as there should be!
In any event when things don’t go to plan, it will be subject to review by the various agencies who participated. The aim of which is to understand what occurred and to ensure that reoccurrence is avoided in the future.
A week ago a hazard reduction burn was implemented at Woronora Heights, where crews worked hard to get it to burn, a week later, a hazard reduction escapes with conditions more akin to a summer wildfire.
It is a timely reminder, despite being in a La-Nina year, that fires in the landscape can still be problematic.
Good to see it will be reviewed and accountability will take place. Clearly with the fire behaviour on the weekend the prescription was wrong.
Or the forecast? There are a lot of moving parts in trying to get these things happening. It's never going t be perfect
Another hazard reduction burn escaped containment in North Sydney today. Rain is forecast tonight and tomorrow though so it doesn't sound like it's much of a concern.
I don't think the fire agencies and Bureau have the requisite scientific understanding, technologies, and procedures in place to conduct spring hazard burns in our new climate.
One got away in Tasmania a few weekends ago near St Helens
Pretty scary situation, hopefully the forecast rain arrives soon.

Good location for spectacular photos. I have seen plenty from crews. Typical of this coastal heath, plenty of flame, but they contained it with a secondary line and most of the activity seen was from the backburn put in to contain the extension. Focus was on looking after the historical assets in the area
I'll add that the new Australian Fire Danger Ranting Schemes, coupled with the Bureau's high-resolution ensemble forecast models, will help address these needs. See this report
Anyone see the ABC show last night on extreme weather or whatever it was called? With that dude from the Chaser. Some amazing footage, and more than a little terrifying in general!
Yeah I mentioned in the other 20/21 fire thread. Is mostly quite good, though the usual dose of misunderstanding, or completely incorrect information. I was on a few strike teams with Mullins, he is a good guy to have on the ground, with just a little bit of experience
My favourite was the claim that the woman at a local fire brigade who runs their facebook page, was responsible for triggering the emergency alerts including SMS etc. I can assure everyone that is is a much more stringent process! And some of the other footage from the state control centre showed a couple of the guys who are often in that role, and at the time appeared to be posting either an emergency alert or major fire update
Thankfully North Queensland doesn't get massive bushfires like you southern folk have to contend with. This is in the hills behind Trinity Beach near me. It started Thursday afternoon just below the abandoned building at the top of the ridge and has basically soldered away to the right and left from where it started. No threat at all to life and property so I think the firies are just going to let it burn itself out.
Today 27/10 is the anniversary of the Gospers Mountain fire ignition.
We were driving home over Mt Lambie when wifey looked north and said WTF is that?!
And already Sydney fairies had been deployed to the north of the state for some time. I was helping a friend in Port Macquarie keep up to date with fire threatening her fathers house. The funny part being that he is a senior volunteer and was tied up, so the kids were in charge and not sure of what was going on. What a past 12 months we’ve had.
Can’t imagine the impact for you of not only the result, but how long the worry was there for
Almost 2 months waiting and watching.
Thx to RFS and you for great intel!
Too much rain this week for the rebuild, so different to last year, yet overall, arctic sea ice hasn’t started to form this year yet, the latest in recorded history......
Do you have shed access yet, or is it all locked off as a building site?
Shed almost finished to lockup, hopefully next week and then we can start to store some stuff in it. Will be sharing the space with the builder.
We were building a house in Mareeba some years ago and rented the house next door. I'd known the builder as a work customer for many years, he still hated the fact that we were there 24/7 watching over him
