38.6mm for me so far with a constant strong NNE wind all night, but only getting to around 70-80km/hr by the looks of things (at the airport site, only 40km/hr at my site). Looks as though the back of the main rain band will pass through soon too.

Welly looks to be getting a hammering now, 10.2mm in the last hour and gusts over 100km/hr! nasty!

Heavy rain has started up again here after some heavy stuff overnight. Got turned around 10 mins out of westport as trying to get to kaiteriteri and the roads are flooded and the Ininghua river has burst its bank and the buller river is brown swollen carrying big tree branches and is nearly toughing the bridge access to westport. The person that turned me around from the council said i quote exactly..."The place is falling to pieces".

Also, the parents stayed in Kaiteriteri last night and they said they are digging trenches in the camping ground and that wind snapped the Gazebo(cant spell) and a tent fell on a lady last night which they had to help her get out of. A couple of tree branches have smashed some cars in the site!

Pretty significant rainfall here at present, but nothing we haven't seen several other times in a wetter than average year. Wind speed does not seem to be anything special where I am.

Strong Northerly gusting 90 km/h and 6.0mm rain so far here. Hoping for more rain out of this sytem yet as our pastures are extremely dry. Baro 994 and dropping Humidity 80%, Temp 21.9C.

Rwood - can you manage to push some of that rain over "the hill"to the Wairarapa? :)

Apparently Havelock is cut off by floodwaters, not surprising given how much rain the region has had in the last 10 days or so, I have had 205mm of rain now since the 16th December so I'd imagine higher areas would be well over 500mm for the same period.

I'm not surprised about the Buller being really swollen CHCH Weather Chaser, was up at the source on Sunday and it was still pouring into it at a good rate, wouldn't have taken much to turn that into flood mode. Hopefully the sandflies up there took a quick trip to the west coast too!

Anyway the rain has stopped now and the wind is now just a gentle breeze, still overcast though but a lot brighter.

Sounds like a few rivers in flood around the top of the south:

Just noticed they've updated it to add;
The Rimutaka Hill Rd was closed shortly before 10am, where gusts of 150kph were recorded.
Luckily the high tide here was only 3.8m, another 0.5m could have been bad news for the Maitai and surrounds.

45mm of rain between 2am and 10am in the eastern suburbs of Wellington, but "the tap" has now been turned off. Max gust of just over 70kmph, just before 4am (but we are very sheltered from the north where we are).

One of the benchmarks for Rakaia would be 26-27 Dec 1957, when Mt Cook had about 500mm rain, and over 1250mm for the month.

7mm this morning from the NW front, wind now around to the SW.
It has warmed up a tad with some sunny breaks on 18C, but you can see the wrapping back in of the southerly over South Canterbury now.
Heres hoping for some decent rain from it.

Thanks for sharing that, didn't even know those webcams existed!

That mot river one is amazing, heaps of large branches and even small trees being carried down by the looks of it, hopefully there wasn't too much mayhem further upstream.

On the St Arnaud one you can even see the small streams coming off Mt Robert on the right hand side, these are only tiny streams usually but look to be a torrent atm. Glad I went tramping up there on Sunday not today!

So much for the northerly gales and 110kmh in exposed places,maybe 40 in gusts overnight was it that high in Howick?The SW will be stronger no doubt especially if the pressure rises quick over the next day.

My station is sheltered from the Northerly by the neighbour's huge trees. The weather station down the road from me (fairly exposed to the N) had a max gust of 45km/h overnight. Definitely exaggerated :smile:

Light rain setting in here.

I see temps are only around 11C down much of the SouthIsland east coast, looking like a cold afternoon for Canterbury /Otago with the cold trough crossing;
