more reports from Waiuku...of an eye witness...
"Anyone get hit by that tornado or cyclone thing that came through waiuku earlier ? It through our kids slide over our gate in to the driveway and lifted the front of our poptop caravan off the ground and every thing on our deck went either across our yard or over the fence and one of our seat cushions has full disappeared. I looked up in the sky and leafs and rain was circulating farkn crazy. Glad it only lasted a min or 2. But heard the fire siren go off a couple of minutes later."
the clue there is seeing leaves etc rotating up the sky :)

I talked to a guy repairing his roof in Waiuku and he said he talked to someone who was walking along who saw a funnel
Yeah I now think the te awamatu event was likely tornado As well as areas of flooding You been mentioned by newshub by the way. Yes definitely tornado.

Only managed to grab yesterday's 12:52pm radar image from the 24 hr images. I think the cell was moving ESE, so perhaps the previous 7 minute image may have revealed a little more (pushing the 120km res limit though)?

@Nev
the CB that developed over Waiuku actually developed very quickly, basicly like a tail end charlie, at the end of the main line
it went from sunshine to building clouds to a nado with sudden heavy rain then a sudden wind change then back to sunshine all the in the space of about 30 minutes :)
i.e so you would need the right frame on the rain radar..the 1pm one would the one :)

The forecast soundings on pivotal weather were certainly indicating large hail. Unfortunately storms were very isolated, probably because of a cloudy morning which meant not much surface heating. And the set up moved away by mid afternoon.

Would of like to see the radar imagery for the Geraldine downpour yesterday. There were some red bits on the imagery around 4 to 5pm-ish but I didn't save them.

I was at work in orari at the time of that downpour so didn't see the radar at the time to save them but haven't seen such heavy rain in many many years.
