Just found a pdf here Mick.
It will turn to snow before long
Yep, but watching the news last night you would have thought what happened in Radelaide yesterday was going to hit here today exactly the same.
That's were you went wrong.... watching the news.
The measuring instrumentation has been deployed on the cedarwood cam. Or someone got an early thirst. One or the other.
They obviously don't read our predictions thread
It refers to the speed and direction of wind as you move vertically through the atmosphere.
It is particularly dangerous to aviation.
This is true.
Yes - generally BOM will report wind speeds at different levels - they refer to this as shear.
A 737 plane circling around Buller... this storm is wrecking havoc on planes
Interestingly the uppers are not very cold here in Melbourne (or Mt Gambier) for that matter
But in Adeliade (6 hours earlier)
Look at that, 50knt+ at 500 hPa levels
A couple of mates made it onto ABC 24 last night for Blackoutgate (one of their sisters is a reporter) and I had to stay up to watch the evidence.
Edit: More. Those girls are funny. Yeah Andrea, I don't see what the big deal was either. Germans. Nice matching scarves you dorks.
Stay on topic.
And Melb at 850 hPa .....
Evidences again the reports coming from Hotham etc.
Lots of rain north of the Divide.
My folks tell me they had 23mm in Seymour after 2am, with a lot of strong winds.
They've got lots of surface water on the back of the rain the other night. The place slopes gently from front to back, with the shed out the back. My old man can't get his car in and out of the shed due to all the water. 41mm for the week.
Great weather for brickies once again.
Some sweet looking rotation and storms on the Adelaide radar.
Although not as impressive looking as the big nasty blob yesterday.
Himawari watching has been impressive
Stopped snowing now at Hotham
It's right on time at zero degrees at TTS at 10am.
Last bit of "Part 1" is to hit Hotham within half an hour. Lucky that we are cold!
I don't have any quality photos worth posting but the colours around Sydney this morning at sunrise as absolutely amazing.
Similar around Wang. My bro had 29mm this morning and can't walk on his lawn it is that soggy.
Went from 2.4C at 9am to 0.0C at 10am.
Snow @ Buller
Okay decided a poor photo is still better than none at all. This morning around 5.30am. City is far right of the photo.
Rather bleak at Lake George.
The glow in Bondi that woke me this morning.
Rain turning to sleet now in Thredbo Village. Good. Needs to get a degree or two colder and we are away....
And with daylight saving time starting Sunday 2 am any glows will be an hour later so you can sleep in... W
Snowing at Hotham again... it better be heavy.
Should be okay. I'm sure my mum will let me know if there's any problems as she's a news addict
Obs out of Adelaide suggest tonight and tomorrow morning could be tough up high.
Tide heights are much higher than predicted on the S coast today. I just watched a video of water all through the carpark at Warneet on a tide that should not have it anywhere near that high.
This is due to the Inverse Barometer Effect.
Tides are calibrated for 1013hPa, but if pressure higher than this, the sea level is lower 1cm/1hPa and if the pressure is lower, the sea level is higher by a same rate.
So a really deep low will bring with it much higher sea levels, mix that in with wind setup from strong onshores and you get storm surges.
Mt lofty received over 60mm yesterday till 9am this morning and has banged on another 5mm since this morning..
Lake is filling up
Heard they recorded 974 somewhere in SA.
dumping wet snow at perisher
We have more experts on this forum than anywhere else and we sometimes stick to the facts. We a need a similar forum on global politics. The main stream media is competently crazy.
Hows the fetch (45 to 64 knots) smashing SA and Vic. You usually get these babies down 50 to 60 degrees South.
When it comes to Ocean WX Craigos is the (well respected) man. The fountain of knowledge is published on SwellNet, almost daily.
Good having you around @SAsurfa
Yeps its good to have everyone on here observing natural phenomenon. I Observe its my salvation from daily crap on the internet.
1013? There has to be a story to go with that.
Isnt 1013 usually taken as the 'mean' sea level pressure for Earth? That's what 1 atmosphere is calculated at.
That's my take on it. Stable Standardized MSL Global Pressure is 1013hPa.
It would be better if it stayed down that far for the surf, so close it has no time to organise. The swell hitting the coast is a real mish-mash of different periods and directions. There was some big movements off Cape du Couedic but we seem to have lost contact with the wave rider buoy they have off-shore when swells to 10m started coming through regularly this morning.
Thanks guys, I just froth on all of this weather stuff as much as any of you, but also have a different angle coming in from the Ocean/Surf Forecasting profession.
That's some resume, glad to have you on board @SAsurfa
