Thats a nice area of instability out in the north Tasman. A hit and miss day for thunderstorms today over northern NZ but there is obviously a strong risk over Northland and this spreads south into the Auckland area this afternoon with the frontal system.

i think dad has a short on one of his fences around the house. The boltek is picking up between 40 and 50 strikes per min in a very dense patch. ill ring him and let him know.
EDIT: problem solved. He had a big short sparking away just 150 metres away from the house

A small tile of images taken at 07.45hrs this morning from Cooper's Beach -the approaching rain band was impressive - I will be working on the bigger images (6 in total) this morning - did try to post a bigger image of the tile but is to large in size to post on forum.

pretty sure i just saw a funnel cloud out past Rangitoto. It was very hard to see properly though. Cloud was hanging down in a funnel shape then quickly lifted back up. So im partially confident it was a funnel. Quite a fat one too.
