Squalls and Thunder, Western parts of both Islands 9-10 July

[jamie]

Looks like round 3 is alreay upon us.

Dale has had thunder during the night on the west coast of the South Island.

I am picking up heaps of strikes to my SW already. Too bad the Taranaki radar is out at the moment as Taranaki really looks the place to be for good storms today and tonight.

Thunder and lightning here in Tawa. The last roll of thunder scared the crap out of our cat.

Harmless conditions in W'gton city today. Bright sun till 2pm with all the ugly stuff travellling past to the north. Then a period of cloud and a couple of light showers, and a clearance. Fresh NW occasionally strong, air now feels considerably cooler.

[Tornado Tim]

Palmy is in the firing line I think going by radar....

[GreggWard]

Palmy is in the firing line I think going by radar....

I hope so Tim. I'll let you know what happens.

[tich]

Record Rain in 1 hour for us with 10.6mm in 40 mins from this event. Records from Davis WX Station go back only two years though.

I thought the Tararuas would shelter the Wairarapa in stormy northwesterly conditions.

[GreggWard]

Lots of lightning to the SW through the NW of Palmy. The lightning seems to be coming from several storm cells. The most active storm cell seems to be the one to the SW, down towards Levin.

[CHCH Weather Chaser]

Yet another severe thunderstorm warning issued a few mins ago!

[Tornado Tim]

My sister says its going off where she is in Palmy.
I have stopped posting the warnings as there are so many of them, LOL

[jamie]

[GreggWard]

Just had a fairly active thunderstorm pass over the northern part of Palmy. Lightning every 10 seconds.

[NZstorm]

Thunder here now!

[GraemeWi]

Hail, thunder and lightning in Henderson now

[GreggWard]

Another thunderstorm cell has just passed over in the last 10mins. Still more lightning to the W-NW.

[David]

Thunder here now!

I heard a single brief rumble around the time you posted that, but assumed it wasn't thunder since there was none forecast for us...seems it was isolated as have heard nothing since. Brief heavy shower last 5 mins.
