Wellington can expect winds of up to 110kmh on Saturday as MetService warns of a 'serious situation' of weather for the North Island.
MetService is forecasting a wet and violent Saturday for Wellington with southerly gale gusts of up to 110 km per hour and rain until nightfall.
Temperatures would reach a maximum of about 15 degrees but would feel colder because of the strong winds, forecaster Geoff Sanders said.
MetService meteorologist Daniel Corbett said a deep and vigorous low would pass over the North Island on the weekend.
"This is a serious situation and poses a weather hazard for many North Island places. Gales are expected over all of the North Island. These may be severe and damaging in some areas, particularly on Saturday morning."

DEVELOPING STORY --- WeatherWatch.co.nz forecasters have high confidence that a significant and rapidly deepening low this weekend will reach "weather bomb" criteria - where the air pressure plummets 24hPa in 24 hours. This is much faster than the usual rate for a storm to develop.
Head weather analyst Philip Duncan says the storm will be timed to rapidly develop on Saturday while it actually crosses the North Island. "It will go from a non-existent mark on our weather maps today to a nasty storm by Saturday morning - with the bulk of the deepening happening in a 24 hour time frame".
The weather bomb is expected to bring gales force winds to many parts of the North Island and in extreme cases those winds will be destructive.

The weather is expected to get cold and very windy for the next two days. It is very windy here today in the Waikato with strong to gale force Westerlies gusting to 45km/hr here in Tokoroa. Canterbury is suffering high winds and very cold temperatures for this time of year too.
Contect:
The MetService is warning the North Island faces a "serious situation" on Saturday, with severe gale-force winds expected to cause damage.
MetService meteorologist Daniel Corbett said a deep and vigorous low would pass over the North Island.
"This is a serious situation and poses a weather hazard for many North Island places. Gales are expected over all of the North Island. These may be severe and damaging in some areas, particularly on Saturday morning."
Corbett said the forecasters still had to see the whites of the storm's eyes, but the wind could reach 120kmh and sea swells 6-8 metres.

DEEP LOW EXPECTED TO CROSS NORTH ISLAND SATURDAY WITH HEAVY RAIN AND DAMAGING GALES IN MANY AREAS
A low is expected to deepen rapidly over the Tasman Sea today and cross the North Island on Saturday. Warnings for severe gale force winds and heavy rain have been issued for much of the North Island and the top of the South Island.
This watch is for the possibility that rain in Hawkes Bay may reach warning levels during Saturday and for the risk that southwest gales over Northland, Auckland and the Coromandel Peninsula may reach severe gale force at times Saturday morning.
People are advised to stay up to date with the latest forecasts in case this watch has to be updated to a full warning.
This Watch will be reviewed by 9pm Friday 2 March 2012

It looks like we're in for an "interesting" weekend. MetVUW forecast charts have the eye of the system tracking right over the Hawkes Bay. :o
Watch my website, especially the LIVE page, and I'll also report in the Today's Weather thread... :(

Severe weather warnings cancel Interislander sailings.
Due to the severe weather warning issued by the Met Service we have made the decision to cancel scheduled Interislander sailings after the 6.25pm sailing from Wellington to Picton this evening.
“The safety of our passengers is our first priority and with both the Met Service and Civil Defence issuing warnings about the weather it is simply too risky to continue sailing” says Acting General Manager Interislander Ross Allen.
“We are extremely apologetic to our customers and hope they will understand our rationale for cancelling the sailings. We are now working to contact affected customers and to move them to alternative sailings outside the weather warning period.”
“If the weather allows, we hope to resume sailings on Sunday morning.”

'Nasty storm': Power outages possible:
Power company Vector is warning customers across the North Island to be prepared for possible power outages, as a forecast storm gets set to hit the country.
Tens of thousands of people are likely to have their planned weekend events dampened by forecast heavy rain and gale-force winds.
Organisers of major weekend events were last night hoping for the best but preparing for the worst as a "nasty storm" bore down on New Zealand.
It is due to make landfall tonight and get more intense as it makes its way over the North Island tomorrow, forecasters say.

OK, now let me be devil's advocate. Will it be as bad as all this or not?We have had a number of hyped up weather events in recent years. This is one of the greatest yet.
-
Well, it was predicted to be destructive and it seems it was. I wouldn't call that overhyped - seems it was pretty accurate.

This is a discussion that I would like to have, when all reports are in, so we can compare the predictions with the results. The end result, where I live, did not match the predictions- it was a just a moderately windy night. We have had dreadful weather events in the past, and I cannot see this event being on a par with those. But the media are using the language of hyperbole to describe what is just a short, nasty storm- we will have plenty of others in the future.
Shall we create a new topic, a little later, to chew this over?
Cheers
Tom
