Looking like it is unsatble over much of the country today and tomorrow. Metservice has most of the country as getting some form of a thunderstorm.
Hopefully there is a craker of a thunderstorm in auckland.

The fronts set to cross the N island are looking to be very active.

Yes that would be nice wouldn't it? Last year October was ushered in by heavy thunderstorms during the first days in Auckland, with some central locations apparently receiving 110mm. I had 46mm. Looks to be another thundery start to mark the month (hopefully).

A nice chance of thunder in Chch as well...and maybe a bit of moderate hail as well.

That's tomorrow for Christchurch and Canterbury - maybe something will actually happen down there this time?
Would be great to get another night time thunderstorm here - most thunder and lightning seems to happen during the daytime since I've been observing

It's worse when you actually live up here and are waiting...the only clues you get is if the rain has reached the west coast yet or when the skies start dimming.

Looking at this site on the Wellington coastline:
http://joker.41south.net.nz/weather/weather.htm
shows average wind speeds of 70kmh and gusts to 112kmh

Rural forecasts for northern areas also say winds rise to gale this afternoon with possible gusts to 110kmh. Not all that strong here at the moment - I'd say gusts to 40kmh.

Also I'll add that the event of heavy rainfall on the west coast has already dumped 156mm on the Arthur's pass station.

Updated Thunderstorm forecast for Auckland:

Severe Convection/ Thunderstorm Outlook

Valid to: 12:00 am 2 Oct 2007 NZDT
Issued at: 2:06 pm 1 Oct 2007 NZDT

A frontal band is moving over the South Island, and ahead of it, another frontal band in the Tasman Sea should move onto the North Island this afternoon. Both these systems should lie east of New Zealand tonight. These fronts bring a moderate risk of thunderstorms to western parts of the country, also Bay of Plenty.

Another frontal band with embedded thunderstorms is moving onto northern New Zealand from the Tasman Sea. There is a high risk of thunderstorms with this feature this afternoon and evening about Northland, Auckland and Waikato and Coromandel Peninsula, and there could be localised heavy falls of 10 to 25mm per hour.

There is a low risk of thunderstorms about the southwest of the North Island and the Marlborough Sounds.

Some localised heavy rainfalls up to 25mm per hour are expected along the South Island West Coast, easing behind the front. In the North Island, localised wind gusts up to 110 km/h are expected with thunderstorms as the fronts pass over.

No thunderstorms are expected in the east.

Wow, just got 43 hits on the lightning tracker in a minute.

Bulk of the storm activity is north of the city.
Occasional thunder here and the odd overhead lightning flash, mod rain.

What is the general ruling on lightning with time and distance? eg how many seconds between the stike and noise to be 1 killometer away

C-Nimbus · Unread post by **C-Nimbus** » Mon 01/10/2007 14:42

For once its great to be an Aucklander

Good stuff this, heaps of lightning and rumbles!

I have heard that if you can hear the thunder then the strike is less than 10 km away, and i also think that the old one second, two second, three second thing is a load of rubbish as air density will change etc etc.

Therefore i stick with the 10km rule

Michael · Unread post by **Michael** » Mon 01/10/2007 15:18

It appears to the east now,been about 10 peels now

We have some very heavy rain on and off over the last hour here in Albany, at our Bush road depot.
Occasionally some good lighting and some thunder.
