That depression the isobars south of Invercargill were spaced out much more than over N.Z Especially when they are more southerly.

Yep - thats exactly my point - they aren't like tropical storms. The worst winds were actually over NZ. But in saying that, gusts to 200km/h would've been possible out on the open waters.

Re: Big Antarctic Low 16-23rd September 2010
Is the brunt of this front going to head out east to sea & miss Christchurch? The radar seems to indicate that it is?

You should see flashes to your east and to your NW.Weetbicks wrote:Is the brunt of this front going to head out east to sea & miss Christchurch? The radar seems to indicate that it is?

It should edge its way up weetbicks, it was quite deep development at 10pm over south canterbury.
I dont know if the tracker is right but its started picking up a few strikes in the area to the south, i guess the 11pm radar will tell us.

Normanby tuning in.... lots of bright flashes in the sky and loud rumbles and bangs afterwards. Not the usual "across the sky" lightning but much more "flash bulb" type stuff in a small sector of the sky. Very bright and white.
Couldnt get more technical if I tried LOL
Very windy with squally showers...

Re: Big Antarctic Low 16-23rd September 2010
Last night when I looked, about 9pm, the dewpoint at Hokitika was 9C and the dp at Chrstchurch 0C. Both locations had 500mb temperature of -30C. But the 0C dps over Canterbury make convection impossible where as the 9C dp on the West Coast is a highly unstable number in an airmass that cold. The surface dewpoint temperature is one of the best ways to get a quick measure of convective potential in a given airmass.

Re: Big Antarctic Low 16-23rd September 2010
Thankfully we miss much of the wind here that you get around the Manakau Harbour, I dislike windy weather.
Milder this morning, currently 13C, dewpoint 9C. Days ahead look much warmer for NZ.

Re: Big Antarctic Low 16-23rd September 2010
Much lighter winds today now that it's turned WNW again, thankfully. 2 of our small (less than 2m) trees down the back just about blew over yesterday, but the fence stopped them. The sodden soil didn't help them stay upright either..

Re: Big Antarctic Low 16-23rd September 2010
Just as windy up here as it has been since friday.. howling house shaking stuff.. if it was going to lift the roof 4am this morning would have done it. Sure built this place stong when they did. Lots of small branch & tree damage between here & Pukke this morning, even the old long drop dunny at the end of my street didnt hold up, lost its roof & one side of it has caved in.. bit of a shame, its an icon for those that live along here

Re: Big Antarctic Low 16-23rd September 2010
Yeah that last squall that just came through was borderline friday night stuff, I dont know if its the orientation of this house or now but I swore I could see little precip vortices dancing around the front verandah (which faces in a westerly direction).. pretty cool to see but in the end closed the blinds incase the windows blew in.

Mmm.. hope so, im getting a little tired of it all now lol.
Really must invest in a wx station up here, I did apply in the ad for the new Pukke one but the guy in Puni ended up setting it up.. oh, and a wind turbine up here too!

Re: Big Antarctic Low 16-23rd September 2010
Heh, spoken like a true chaser / enthusiast.
Now I can see again, the high stuff looks to gone over with that front.. just a lot of low crappus dribbling through (albeit quickly) so hoping its all over red rover for now.. this place is a mess after near a week of nuts winds, surprised all my parrots have held up now were coming into breeding season.
