Cyclone Cook storms down New Zealand

The remnants of the tropical cyclone named Cook hit the Bay of Plenty yesterday afternoon and is still storming down New Zealand. It is expected to track down to the east of the South Island today.

The North of the North island including Auckland weren’t hit as badly as predicted but slips, damage and power outages are reported from other areas.

The extent of the damage will become apparent during today.

While there were warnings it may have been as bad a storm as Giselle that struck in 1968 when the Wahine sank in Wellington it seems to have not been as intense or destructive.

  • The worst of ex-Cyclone Cook is over. It’s currently sitting south of the North Island, moving south and weakening. However, it may bring strong winds, heavy rain and possible flooding to eastern Marlborough and Kaikoura on Friday morning.
  • The storm is expected to sit east of Banks Peninsula about 9am on Good Friday before lying east of Oamaru about midday, and well east of Dunedin in the late afternoon.
  • Strong winds are expected in Wellington early on Friday morning, and around Kaikoura and Banks Peninsula later in the morning.
  • The storm has caused flooding and slips on the North Island’s east coast, with numerous roads closed.
  • The Motueka Valley Highway has been blocked by a slip near Stanley Brook.
  • Power is out in many North Island areas. Whakatane, Te Puke, Opotiki and Waimana have been hit by blackouts, along with Napier and Hastings. More than 2000 customers have lost power in the Hawke’s Bay and Gisborne regions.
  • Air New Zealand has suspended operations from Tauranga Airport.
  • States of emergency are in place in Thames-Coromandel and the Bay of Plenty.

What happened overnight?

“The worst of it was last evening when it came through Bay of Plenty. At midnight, the low was passing over southern Hawke’s Bay and over northern Wairarapa. The strongest winds around Bay of Plenty were last evening and the strongest winds around Gisborne and Hawke’s Bay were late evening up to about midnight.

After midnight, the strongest winds have mostly been about Wairarapa and they were gusting up around 100kmh, mostly about the east coast of Wairarapa – Castlepoint and those sorts of areas.”

RNZ: The lowdown on tropical cyclones

As Cyclone Cook passes over New Zealand’s east coast, cutting power and closing roads, Alison Ballance looks at the science of tropical cyclones.


Have we been lucky? 

“We have in a way. It tracked a little further east than some of the original predictions, which means that Auckland in particular didn’t get affected by it, and it probably wasn’t as deep as some of the initial predictions as well.” – MetService severe weather forecaster John Crouch

Some people seem to think that weather forecasts and warnings are promises. They are just (usually fairly accurate) predictions of probabilities. Things often turn out to be not as bad or a bit worse than estimated.

Over-warning is better than under-warning.

    Calmish (we are sheltered from the southerly) but damp in Wellington. Wahine storm it was not. Must have been a quiet news day.

      It was a bit of a Claytons event here-but I suppose that it’s better to be prepared for a bad one than have an unpleasant surprise.

      There have been some forecasts lately that were the opposite to what the weather actually was. Rain every day for a week….but none came.

    I believe St John Campbell extended his show so as to be able to emote with the victims of the National Government failure to do anything.
    As for the Green Party clowns 🤡 who immediately claimed it as evidence of climate change.
    Double fail.

      What does he THINK they should do ? Tell the cyclone to go away ? Pass a law saying that no cyclones are permitted in NZ ?

      It must have been jam for the Greens, of course.

    I don’t know what the wind’s like in South or Central Welly but in North Welly it’s still calm as.

        Oh, sorry Brown, didn’t see you up top there. Sounds like God has spared your end of Welly from the tempest too. 👍

    • The rain is picking up again here in Dunedin (we had a few hours break in the middle of yesterday) and it’s supposed to get a lot heavier this afternoon, but nothing drastic compared to elsewhere.

        No rain here, I think that it stopped last night. There was about 40mm in the rain gauge-a bit less.
