The latest on the approaching system

Rain has been falling in Northland this morning, much of it fairly light, however heavier rain is soon on the way.

The light rain is now moving in to parts of Auckland and Coromandel Peninsula.

The light rain is associated with a warm front.  Behind the warm front is an occluded front (where a cold front and warm front have merged).  Occluded fronts are often responsible for some of our heaviest rain bands.

The occluded front should lie almost stalled over Northland and Coromandel Peninsula starting this evening and lasting well into Monday, according to the MetService weather charts.

On top of that, with the low still deepening, winds – which are mostly light at this stage – will strengthen to gale force.

The Far North and eastern Waikato, along the Kaimai Ranges, should be the first to feel the wind’s strength.

From Waikato to Otago winds are mostly light and skies are clear as of 7:30am.   Christchurch has -3 this hour.

But a weak front has helped boost temperatures in Invercargill where it’s matching parts of Auckland with 8 degrees this hour.   Auckland is currently between 8 and 10 while Whangaparaoa has 13.

Oddly just north of Christchurch in Kaikoura it’s 10 degrees thanks to a westerly wind coming off the mountains.

Where are the Gale force winds

WW Forecast Team on 3/07/2010 10:54pm

We don’t expect widespread gales, only in exposed coastal areas and those directly west of main divides.

In saying that, the winds are most likely between 6 o’clock tonight and noon tomorrow.

Hi there WW,
So are these winds going to have some grunt to them. It’s dead calm here at the moment fog and cold (calm before the storm) keep us updated Thanks

Hi there,

The winds are still many hours away – it will most likely arrive tonight and into Monday morning.  We estimate gusts over 120km/h for Te Aroha which is damaging, but we don’t, at this stage, expect any serious damage.

Keep up to date with conditions – as it’s still developing.

Takes only a day to move across the tasman/deepens then takes a week to move parallel down the east of the NI,with only the backend colder rubbish.Typical.
