Storm Update: Rain falling in the north – winds building

Winds in Auckland are picking up while steady rain is falling across many parts of the North Island already, ahead of the low pressure system approaching the country. is now forecasting the low to track close to Auckland on Wednesday – but the severe weather for the upper North Island will arrive this afternoon and evening, ahead of the centre.

Latest rainfall data shows Whitianga is the wettest part of the country, receiving more than 2mm of rain this morning, while the worst is yet to come for the entire Coromandel region.

At this stage Coromandel Peninsula may be the region most exposed to severe weather, with the strongest winds and some of the heaviest rain hitting the area.

Winds are building in Auckland too, going from 20km/h to an average of 35km/h between 10 and 11am.

The Auckland region lies on the edge of the severe weather in Coromandel Peninsula and the severe weather in Northland. The centre of the low will actually cross Auckland City just after midnight tonight.

Rain could be heavy for a time on Tuesday afternoon – especially north of Albany and about the Waitakere Ranges. Winds may be the main feature of this system for Auckland, with gusts of 110km/h possible late Tuesday afternoon in exposed coastal areas of the east – in particular, WHANGAPARAOA, GREAT BARRIER ISLAND, WAIHEKE ISLAND, HOWICK to HUNUA RANGES (coastal). It’s hard to say which suburbs will and wont get gales – but power cuts are possible in ANY suburb.

Even if not stormy where you are (which could be a big chunk of the city due to the georgraphy of the upper Norh Island) this is definitely a good reminder to have a Survival Kit. Visit Civil Defence for more info.

Northland is also exposed to this low with the centre of it making a direct hit to the region on Tuesday evening. Some of the heaviest rain may affect eastern Northland on Tuesday afternoon with a risk of surface and flash flooding – especially on top of the weekend’s thunderstorms. Strong to gale force winds are expected but severe gales may be limited only to exposed hills and exposed coastal areas in the east and south east. The westerly change behind the low later on Wednesday and into Thursday may be even stronger for Northland.

No repeat of the weekends thunderstorms are in order – however any sub-tropical low could form a few thunderstorms here and there. Note, the thunderstorms on Saturday night were created, in part, by fairly calm weather. This will be anything but calm for much of the North Island.

How are conditions at your place? Are you starting to feel the approaching system already? Let us know in the comments.

11:47pm, Henderson, Auckland:
Winds are picking up all the time and rain seems to have ceased after 12 hours of constant rain. Blowing pretty heavy out there at the moment but not the worst I’ve seen.

Hi we live in Orewa and rain is getting heavier and the wind is definatly picking up…

Chris on 24/09/2013 2:25am

We had torrential rain in the Bay of Islands this morning abt 0200. No wind. Now 12 hrs later just light rain with moderate SE wind.

Are you still sure about all this?

Looks more like a standard sub tropical low, with only moderate winds.??

Current 2000 ft wind, only 20 knots.

Can you provide an update on whole scenario?

Severe gales possible around a number of parts of the upper North Island – but we don’t think most of the main centres will be too badly hit.  We have updates across the day on our homepage.  Civil Defence has also activated and are warning of storm conditions overnight in Auckland.  However appreciate what you’re saying – this low on its own is a borderline "storm" but the geography of the upper NI will create far more intense rainfall totals and much higher wind speeds.

What will it be like in Pukekohe? It is raining here now but not windy at all.

WW Forecast Team on 24/09/2013 12:56am

There are always going to be anomalies within the forecast but we are trying to look at the big picture here. In general the Auckland forecast is for you and shows our thoughts for the city.

But in saying that Pukekohe is more to the south. I’d say you have a lesser risk of heavy rain and strong winds then in the forecast, but only a slightly lesser risk.

Would you say the worst winds will affect the Coromandel until about midnight? In what dirction will the wind turn to over the Coromandel when the low centre is over Auckland?

I believe this article should help you out:

But yes you are correct. Winds will be strongest this evening, winds swing round to the northeast later this evening then easing overnight.
