Mountains of snow for Australian hydro

 

It delivered. The Antarctic airmass which has held southeastern Australia in its icy grip for the past two days has brought a serious dump of snow to the mountains and beyond. It has been a cracking start to the snow season for NSW and Victorian Alps, where major hydro power operations take place in Australia.

As expected, ski resorts have received in the vicinity of 40 cm of snow from this storm, which will ease later today. Perisher in NSW – which is always favoured by the sort of northwesterly winds which accompanied this system – is claiming as much as 60 centimetres of fresh snow.

Nearby Thredbo has also seen upwards of 40 centimetres of snow, while Victorian ski resorts have all seen similar amounts as their NSW counterparts.

Picnic-table-o-meters have long been the snow depth measure of choice for both Falls Creek and Mt Hotham, and the tables again told the tale at both resorts on Wednesday morning.

Snow has also fallen in areas beyond the ski resorts. This image of the Tidbinbillas to the west of Canberra (often wrongly called the Brindabellas, which are actually one range further back!) shows snow down to about 800 metres above sea level.

Snow to a depth of at least 5 cm was reported on the Central Tablelands of NSW – a dash cam video of a motorist driving to Shooters Hill near the town of Oberon (elevation 1350m) is doing the rounds which shows it prety well, as does this Today show aerial video.

Snow has also fallen at numerous locations above about 600 metres in Victoria, including in Beechworth (elevation 560 metres) this morning.

It takes an exceptionally cold air mass to deliver snow to such low levels on the Australian mainland, so as you’d expect, temps have been absolutely frigid.

  • Both Mt Hotham in Victoria and Thredbo Top Station in NSW hovered well below -3°C all day yesterday, with both stations losing a few more degrees overnight.
  • At Thredbo Top Station, the temperature at 8 am this morning was a bitter -6.9°C, with an apparent temp (or “feels like” temp) of -21°C, due to strong northwesterly winds gusting up to 60 km/h.
  • Meanwhile, Canberra is heading for a maximum of just 8°C today. When locals say they can feel the icy wind blowing off the mountains, they’re not kidding. At 10:50 am today, the temperature in the national capital was 6.3°C but it felt like -2.5°C.
  • It was also a bitterly cold start to the day in places like Orange on the NSW Central Tablelands, where the temp was just 0.9°C at 10 am, with an apparent temp of -7.1°C!

Conditions will start to moderate across most of the southeast later today, before another round of cold, windy weather kicks off towards the end of the week, with more snow in store for the mountains.

Signs of a positive Indian Ocean Dipole, but it may not follow the textbook

Waters off Indonesia have cooled in recent weeks, an indication that a positive Indian Ocean Dipole (IOD) event could be developing. It’s an important climate driver for Australia, and it could shape rainfall and temperatures heading into summer, with flow-on effects for farmers, energy and other industries.  What is the Indian Ocean Dipole?  The IOD […]

1.3 million lightning strikes and a record September downpour: the storms testing WA’s Goldfields

Leonora, WA, had its wettest September day on record earlier this month. Three weeks later, more than 1.3 million lightning pulses were detected within 800 km of the town in 48 hours. Why is a stalled trough delivering storms to mining country, and what it could mean for operations?  The DTN Total Lightning Network detected […]

A very low wind power week, likely to continue

A stubborn blocking high over southern Australia will make for a very quiet week for wind generation and the pattern behind it isn’t a one-off.   It’s the seasonal signature of a super (very strong) El Niño combined with a positive Southern Annular Mode (SAM), and both the historical record and the current seasonal forecast suggest it’s likely to keep recurring through spring before a potential switch from November.  The setup right […]
