-        Snow, sleet & below zero wind chills


A reminder that winter is not yet over - a short but sharp cold snap is set to bring freezing wind chills and snow to low levels across some parts of the South Island over the next two days.
The Radio Network's head weather analyst Philip Duncan says two cold fronts will deliver a burst of Antarctic air to the far south.  "The first cold front will arrive in Southland late Tuesday morning followed by another one later on Tuesday night.  The second front will bring snow falls to low levels and sleet to sea level".
Duncan warns farmers to be vigilant of wind chill stress on newborn stock.  "Wind chills well into the negatives are likely from Tuesday night until Thursday morning.  Winds will be very strong from the south west, mixed with the polar air it wont be pleasant for humans let alone newborn lambs”.
Wednesday will see snow flurries across Central Otago and sleet continuing across the southern part of New Zealand.  "'Feels like' temperatures in Invercargill, Queenstown, Dunedin and Christchurch will be lucky to get over 3 or 4 degrees on Wednesday".   Duncan warns roads could be very icy too about upper parts of Dunedin, Central Otago and Southland.
However there is good news.  "This is just a polar pulse, one short sharp burst of cold energy, then it'll ease, replaced by a large high bringing lighter winds and frosty fine weather".

Heavy rain has set in to Northland but so far has missed Auckland.  A band of widespread rain has set in to north east Northland from about Coopers Beach to south of Whangarei
The Radio Network’s head weather analyst Philip Duncan says there are two fronts moving in.  “A warm front is moving down the north today, which will bring showers to Auckland then rain developing later this afternoon.  A band of heavier rain, associated with a cold front will make its way down to reach Auckland around midnight tonight.  By dawn we’ll probably have a lot of low cloud and drizzly showers over northern New Zealand”. 
He warns there is a “high risk” of surface flooding and slips across eastern Northland this afternoon and drivers should take extreme care. Heavy rain is also expected in the ranges of Coromandel, Bay of Plenty and Gisborne. has been conservative in their forecasts for the past 24 hours and is still predicting only moderate rain falls in the North today.  MetService has this morning downgraded their warnings, acknowledging the front is moving faster than they expected.
Duncan says much lighter westerlies will also be on the cards for tomorrow.  “By noon Friday most of New Zealand will have light winds which is in stark contrast to today’s conditions.  Winds are gusting to gale force about Auckland with city ferry travellers being knocked around by gusts up to 100km/h”.
He says winds won’t ease until tonight.

REGION:  Auckland
“Easterly gales will gust up to 110km/h in exposed parts around Auckland city tonight and up to 100km/h in exposed parts of Auckland city itself.  Those especially exposed are suburbs with eastern coastlines.
Winds will peak this evening and should ease back after midnight.  The direction of the wind, accompanied by heavy rain, has prompted this warning.  Damage to trees and powerlines is possible.  Motorists should also take extreme care on hills and the harbour bridge”.  Philip Duncan, Head Weather Analyst.

+ your WEEKEND forecast

Torrential rain and winds blasting up to gale force disrupted Auckland Thursday night as another Tasman Sea storm moved over the region.  The heavy rain brought chaos to Auckland's roads with gridlock on all motorways at 5pm, leading to serious crashes and commute times taking hours rather than minutes.  Passengers on ferries would've been rocked about as winds gusted to 100km/h across Auckland Harbour.
At 6pm the Radio Network's Weather Watch Centre issued a Storm Alert warning gale force winds would buffet the city for the evening.   Head Weather Analyst Philip Duncan says winds were recorded at 90km/h across Auckland, with gusts up to 110km/h in coastal regions.  He said the direction of the wind combined with heavy rain was the reason a storm alert was issued. 
"This is about the 8th Tasman Sea storm to affect Northland and Auckland in a matter of weeks.  Easterlies are not that common during winter and we've had several weeks of them, including a few days where they reached gale or severe gale".
Heavy rain also caused surface flooding about Northland during the day. 
Auckland shivered as the normally warm nor'easters brought a temperature of around 12 degrees for much of the day.  "While South Islanders might laugh at that, it was certainly noticeably cold in Auckland, that was because the air being dragged in wasn't coming from the tropics as it often does with north easterlies".
A shift to north west winds Friday is expected to warm things up across the country, ahead of yet another low in the Tasman Sea.  The low, which isn't expected to bring any severe weather, is however set to flick another couple of fronts across much of New Zealand late on Saturday.  "It should be a mild start to the weekend with cloud building during Saturday and a few showers turning to rain by afternoon, evening and overnight for some.  Rain or showers should affect most eastern areas on Sunday morning with conditions turning cooler west or south west and a few showers in western parts" says Philip Duncan.
Duncan also says the north west winds could be blustery in northern New Zealand for a time late Saturday and gales are likely for ski fields across Central Pleateau and also about Wellington.
-        Tropical Storm Dean is now expected to become the first Atlantic Hurricane of the season…and may affect America’s south east coast.
-        There are fears in Texas that Tropical Storm Erin could cause serious flooding over the next day or two.
-        A large high pressure zone is expected to form over Tasmania next week... may influence NZ’s weather...with drier conditions.

6 to 10.6 degree frosts (10.6 at Invercargill) are being felt across the South Island this morning as winter keeps an icy grip on the Island this week.  Currently -6 at Dunedin Airport, Lumsden -5 and -4 in both Christchurch and Timaru.
South Island weather analyst Richard Green says care is required on the roads this morning but the sun should thaw out most tricky spots by late morning
Green says on the skiing front, Temple Basin is the first skifield to close in the Canterbury region this winter due to a lack of snow.  Mount Olympus and Fox Peak have yet to open for the season.
There were also a string of negative ones across New Zealand this morning from the Central Plateau, inland Hawke’s Bay, Kapiti Coast, Hutt Valley and Marlborough.
-        A low forms in the Tasman, winds building across northern NZ with gusts to 100km/h in the far north.

More heavy rain is on the way for northern New Zealand.  A low is this evening deepening in the central Tasman Sea and will spread a large rain band over the far north tonight then slowly move south during Thursday to reach Auckland and Coromandel by late afternoon or evening.
The Radio Network’s head weather analyst Philip Duncan says the heavy rain is made worse due to a large high over the South Island.  “The high over the South Island will block the movement of this rain band. That means the heavy rain will move very slowly over the region and that’s prompted warnings for potential flooding”.
MetService is also warning of heavy rain, issuing rain warnings for Northland and northern Auckland predicting up to 120mm for some areas from noon Thursday to noon Friday. is predicting heavy rain to set in tonight in the far north and not ease until overnight Thursday/Friday morning.
“Strong winds are also accompanying this system.  Residents along Auckland’s east coast will have another windy 24 hours with easterlies gusting to gale force”.
Duncan says gales gusting to 100km/h have blasted Cape Reinga all day.
-        Hurricane Flossie (seen here) will brush the lower part of Hawaii tonight and tomorrow but the big island will miss a direct hit. 
-        Tropical Storm Dean has formed in the Atlantic.  Dean is expected to grow into a Hurricane in the next few days and could be a direct hit for Puerto Rico.   Plus residents in Texas are also bracing themselves for another storm which could bring floods in the next couple days.

PLUS:  OUR DAYS ARE GETTING LONGER!...Auckland gets an extra hour of sunlight

The fridge door is ajar!  Chilly temperatures have been recorded right across the Mainland this morning after the polar southerly finally eased.

Parts of Canterbury, Otago and Southland have the mercury below the freezing mark with widespread frosts this morning and our South Island weather analyst Richard Green says although the day ahead should provide some bright sunshine, top temperatures shouldn't hit double digits
“An intense anticyclone nearing 1040 Hector pascals is making its presence felt and for at least a couple of days, clear skies and freezing nights are on the agenda for Southerners”.
He says current readings have Christchurch and Wanaka on -1, Oamaru and Lumsden on -3 and Queenstown with Jack frost on -4
Green says it has been a lean season for some South Island skifields this winter.  “Any snowfall has been welcomed with open arms recently and the good news is that a number of skifields received a good coating of snow over the last 72 hours.  With the forecast of sunny skies today, this should make ski-buffs and operators very happy indeed”
You’ve probably noticed by now, but if you haven’t you’ll be pleased to know our days are getting longer.  The Radio Network’s head weather analyst Philip Duncan has been doing some research and discovered some interesting facts:
“Today Auckland reaches 60 minutes of extra sunlight from our shortest day of the year.  Christchurch is getting about 80 minutes more sunlight and Invercargill an hour an a half more light”
Philip Duncan says each week is getting longer by about 20 minutes.  “The sun’s rising about a minute or two earlier each morning and setting an hour or so later each night”.
Duncan says the next month of so marks the most rapid increase in extra hours of daylight per week.
- A Hurricane is moving towards Hawaii.  It’s expected to hit cold water which will lessen its intensity, but it could still bring huge seas and gales to Honolulu.
- A low is forming in the Tasman sea…will bring warmer nor’esaterlies to the North Island by tonight.

- Large High moving in 
It’s been a wild weekend weather-wise.  A huge Antarctic storm brought torrential rain to both islands, severe gales up to hurricane force and record breaking rains in Tasmania.
But the storm’s strong winds are moving out into the Pacific Ocean now and are about to be replaced by calmer conditions thanks to a large high – and that spells some pretty big frosts in the South and a noticeable drop in temperatures for the North.
“All of New Zealand will feel significantly colder during Monday and Tuesday thanks to the cold air sucked up from Antarctica over the weekend.  This means a big drop in overnight lows for the deep south, with severe frosts about Central Otago and other inland regions” says the Radio Network’s head weather analyst Philip Duncan. 
Hey says temperatures in Central Otago could drop as low as minus 7 overnight Tuesday.
“This will be a brief return to the conditions we had back in July, but the good news is that it will be short lived”.
Duncan says that’s because the next cold front, arriving later in the week, will bring warmer winds.
The stats from our weekend storm:
Wanaka Saturday had thunderstorms and gales that knocked out power.
Hastings reached lower 20’s temperature-wise on Saturday.
Napier had 17 degrees at midnight Saturday (very warm for early August!)
Auckland’s overnight low on Saturday was 15 degrees. 
Auckland dropped 4 degrees in 20 minutes when the cold front passed over Sunday morning.
Invercargill went from feeling like the mid-teens on Saturday to minus 2 within an hour or two.
Oamaru dropped 18 degrees overnight Saturday
Dunedin, Wellington, Taranaki, inland Hawke’s Bay, exposed parts of Auckland– all had winds gusting to 100km/h
Hurricane force winds of up to 150km/h lashed Castlepoint.
Part of Tasmania had their wettest 72 hours in 40 years, warnings of bitterly cold weather tonight.
The storm was one of the biggest on the planet at the time.
- Atlantic Hurricane season now forecast to be not as intense: US Govt statement following a much quieter than expected season.  (worth noting this happened last year too!).
- Spring like temps to return to North Island by Thursday.
- Very warm weekend in Sydney, Aust.  Temps around 25 degrees on Saturday.

-        Warnings of black ice tonight
-        Wind chill stress for new born animals
Snow has fallen in the last hour in Invercargill. 
As predicted by the Radio Network’s Weather Watch Centre snow has fallen to low levels about Southland today following the weekend’s storm.
ZB reporter Malcolm Gayfer says snow fell in the last hour, but the sun has now come out again.  He says snow has also been falling across western parts of Southland today.
Head weather analyst Philip Duncan says conditions should clear overnight leading to widespread frosts and black ice.  “We advise motorists in the lower part of the South Island to watch for black ice tonight.  Roads still wet from the weekend’s rain or snow will likely freeze tonight as temperatures plummet to minus 7 or 8.  Avoid driving after dark and first thing in the morning if possible”.
Duncan also warns farmers to be vigilant of new born animals in stress this afternoon and overnight as wind chills across Southland and Otago drop this afternoon to minus 3 and even colder in the highlands.
Weather.comis predicting the temperature to drop to an extremely cold low of minus 10 in Queenstown tomorrow night.
- Spring-like temps to return to North Island by Thursday ahead of an approaching front.
- Low expected to form in the next 48 hours in the Tasman Sea.

-        Storm the size of Australia sliding to the South of NZ
-        Cold snap moving in – Farmers: “be prepared”
The huge storm that has blasted the South Island overnight is now moving its severe wind and rain into the North Island.  The deep low, which is spread over an area the size of Australia, is in fact well south of New Zealand, but its strong winds are being felt over thousands of kilometres.  The Radio Network’s Head Weather Analyst Philip Duncan, says the worst winds are now moving into the North Island.

Wellington is been pounded by winds up to 100km/h, stretching to severe gale on hill tops at 130km/h.  Auckland is getting gusts to gale force now and up to 95km/h in exposed hills around the city and I expect that to increase in the next 12 hours.  There is the possibility for some damage in Auckland, mainly to trees”.  Duncan says parts of Taranaki, Hawke’s Bay and Gisborne are also seeing gusts up to gale force while Castlepoint has been receiving winds up to hurricane force.
The strong winds are also bumping up temperatures, with 18 degrees recorded in eastern Coromandel Peninsula and a balmy 20 degrees for Hastings early this afternoon.
Overnight the South Island received a battering with Wanaka rattled by thunderstorms, severe winds and power cuts.   
The front main front is now lying over northern Southland where the winds have quickly eased and turned to much colder south westerlies.   “There is a distinctive line were the front is.  Currently in Dunedin gale force nor’westers are reaching near 100km/h and it’s a mild 19 degrees in Oamaru, while down the road in Invercargill where the front has passed the temperature has plummeted to just 4 degrees, and a “feels like” temperature of minus 2 degrees”.
“Another cold front will arrive on Sunday morning in the far South with even colder air behind it - we’re warning wind chills could be extreme and snow may fall to low levels about Southland and Otago.  Farmers should do be prepared to protect their newborn animals”.  Global weather giant is predicting a high of just 6 degrees in Invercargill tomorrow and only 4 on Monday and Duncan says wind chills will be well into the negatives, possibly colder than minus 10 inland.
“The entire country is going to feel a shock to the system in the next 24 to 48 hours as temperatures continue to drop following cold fronts.  It will be a very cold start to the week”.
Duncan says it’s not all doom and gloom though, with warmer temperatures on the way by end of next week.
- Storm could be on the of the biggest on the planet at the moment…air pressure well down below 940mb
- Spring-like temps to return to Northern and Eastern North Island by end of next week.
- Snowfalls likely for both islands ski fields.
