I actually came across that game on YouTube yesterday night. It looked cold but there wasn’t any snow falling. Spewing I didn’t stick with it.
Snow in both hemispheres as I got to experience a light dusting at Nimmitabel this morning. The snow fell in the early hours of the morning but was still lightly on the ground just before 9 AM.
Seroja has looked to have been a direct hit on Kalbarri in WA, BOM reporting that 170km/h wind gusts have been recorded. There’s likely to be some pretty serious damage along the trail of this cyclone as it’s impacted far south enough that buildings, particularly older ones would not be constructed in a cyclone proof way.
Finally some clear blue sky here after nearly a week of hazard reduction smoke. It’s been nowhere near the levels that Sydney and Perth have copped though. Melbourne has also had some smoke at times.
Hazard reductions probably don’t stop the worst fires but since increased HR was a key recommendation of the Black Saturday Royal Commission (and probably the Black Summer one too), the smoke is here to stay. The increased level of HR predates Black Summer though; Sydney has been shrouded in smoke for a good part of autumn since about 2016.
There have been some attempts at cultural, small scale burning around the ACT but NSW still has the ‘scorched earth’ mentality to burning. This needs to be revised as it results in a certain negative outcome (severe air pollution) for an uncertain payoff in terms of bushfire mitigation.
By the way, I have been delving into the ins and outs of air quality today and the below site is probably the best. It converts the Australian readings into the standard US Air Quality Index. The US system is better because it neatly divides the index into six categories; basically anything below 50 is good and anything above 100 is bad, which is easy to remember. Anything above 150 is extremely poor and above 200 you should stay indoors with the air filter. Above 300 is hazardous, at which point you should take a holiday.
It has a nice map too. You can see that most stations around Canberra/Sydney are green today (below 50), with a few above 50 (in the ‘Fair’ or ‘Moderate’ category). Melbourne seems to be copping a moderate level of HR smoke today, with a little residual smoke still hanging around parts of Canberra.
Goulburn is at last in the ‘Good’ category (US AQI= 30) with a raw reading of 9 micrograms/cubic metre. Not before registering an AQI of 135 last night, though.
The Australian indices are based off raw data and aren’t as user friendly IMO. With the US system you only need remember that anything above 100 is potentially harmful. A bit like the old 100F= bloody hot.
It’s interesting to check when there are bushfires or other events in the area. You can sometimes have all greens and then in the one location a red reading of upwards of 700.
Like temperature sensors I’m guessing they give spurious readings every now and then. The problem is that the network of official stations is hardly dense, making it difficult to weed out these erroneous readings.
The home based monitors often give unrepresentative readings due to wood smoke, BBQs etc.
Devonport has some of the best air quality in the world, so you don’t often have to worry about it. I am often jealous of Tasmania’s environment. Launceston on the other hand…
I’d prefer the chilly conditions to what we had on this day 5 years ago with the extraordinary rainfall of over 200mm all raging through the north-west coast of Tas.
Here’s Latrobe which was underwater and I can still remember clearly watching entire trees and livestock and infrastructure going down the Mersey River faster than the cars on the street nearby.
These streets underwater here are ones which I’ll travel several times a week, it was so bizarre seeing the flooding so spread out across the town and it happened so quickly.
People will be driving to the area today to try to see snow . Usually they need to drive up to the heights around Stanthorpe to see any.
Queensland-based Bureau of Meteorology lead meteorologist Matthew Bass said flurries could fall in the Sunshine State as early as Wednesday afternoon or evening but the coldest air would arrive on Thursday, with snow down to 900 metres on the Granite Belt.
