I saw that same yacht on the way into the city this morning. Also saw isolated incidents of tree damage.

Great collection of photos on the stuff website too: http://www.stuff.co.nz/national/4572485 ... ather-over

I particularly like the set of 3 shots (numbers 3,4 & 5 of 59), thats some serious rise in river level over a weekend! 8-o

How unusual is a flooding event like this for Auckland? at first glance it seemed like a 1 in 10 year event but going by what has been said in news reports it sounds a little less common than that. I'd guess the combination of a king tide and a decent swell might be fairly common but not with the addition of a low barometric pressure and heavy rainfall as well?

It floods every 2 or 3 years on average it seems and only a few areas,nowhere the whole city or even a 1/10th,depends on the tide,low centre and usually near waterways and manholes that back fill.

Hi Tim S, storm-surges (or storm-tides) coinciding with summer or winter king-tides don't appear to be that uncommon along Auckland's waterfront; in fact they're almost routine. Check out this photo-gallery from Auckland's last king-tide. However, I'd say this particular event, in terms of coastal flood height and recorded low baro-pressure, is probably one of the more extreme.

Thanks for the photo-link btw. Can't understand why some folks would willingly plough their late model cars through sea-water though. #-o

An exceptionally deep low (955hpa?) passed northern NZ in July 2008 and that raised the sea level around Auckland by about a metre.

968hpa that was from memory
I think at the time luckily the tides were not too big?

Thanks for the info guys, the media always seems to make weather events sound like they have never happened before so I was a little unsure as it did sound like a fairly significant event. As for the king tide plus large swell scenario, sounds like thats almost as common as a Sou-westerly in Auckland's pine forests. ;)

I know an event like that would be about a 1in 10 or 1 in 25 year occurrence around here as I have seen the historical data on storm surge events, as you'd expect its all about timing as you don't need a very deep low after all the difference between a 986hpa low and a 968hpa low is only 18cm of sea level but the difference between a neap and spring tide is going to be around 5-10 times that depending on where you are in NZ.

I went for a drive around to Miranda yesterday
the waves/tide was across the road in many places, with logs and big rocks on some beaches

also some tree damage from the NE wind

good that M/S did warn of this exact thing would happen that day

I heard MetService being quoted by the media that this was 'a one in five year event' for Akld, which in terms of extreme tide, pressure, wind and rainfall sounds about right.

Very good article here ... 'King tide 'lifted' higher by low pressure' :>

Very bad article here ... 'Weather bomb hits Tamaki Drive' :-(

Theres a tidal stream feeding into hobson bay running not far from portland road(bassett road) and that road itself is flat at the shore road end though the other end is uphill.

Okahu Bay resident Anne Clere saw a "mindboggling" wave crash over the seawall along Tamaki Drive, knocking a man to the ground.

"This poor man was trying to walk along the waterfront and the next minute was sitting on the footpath with the wave washing over him."
surely that 'Poor man' would have seen how rough it was and that there was a good chance he was going to get hit by a wave and so to take another route for the daily walk?
do people have no commen sense these days?

Some more local photos of last weekend's floods in these stories from the Waiheke Gulf News and the Waiheke Marketplace (see gallery) :D ...
