Emergency
services in Canterbury were called after a truck and trailer were
overturned on Monday morning on Lewis Pass Rd, Island Hills,
north of Christchurch.
METSERVICE
Ten
thousand lightning strikes were recorded in two hours on Monday
morning.
A
woman was taken to hospital in a moderate to serious condition after
a tree fell on her car shortly before 7.30am on Weedons Ross Rd, in
the Christchurch suburb of Selwyn.
Police
warned motorists to drive to the conditions as high winds whipped the
region.
Power
authorities had been "very busy" on Monday morning with
trees falling on power lines causing outages across South Canterbury,
Fire and Emergency New Zealand Southern communications shift manager
Andrew Norris said.
What's happening in #Dunedin? Temperature linked to wind, and both all over the place! ^TA
Residents
of Kimbell, Middle Valley, Mt Michael and Mt Dobson ski area were all
without power as of 11am on Monday.
Power
had been out since 5am and was expected to be restored by 12.30pm.
26,000
LIGHTNING STRIKES
A noisy night on the West Coast. Lightning risk reduces this afternoon - see http://bit.ly/TSOutlook

Thunderstorms
across the west of the South Island sparked around 26,000 lightning
strikes in 12 hours.
"We've
got an active front moving up the country which has produced a lot of
lightning overnight. 26,000 lightning strikes have been recorded so
far in the 12 hours from 6pm yesterday to 6am this morning! A noisy
night for some of you in the South Island," MetService said.
Lightning
activity was expected to pick up again later in the day, MetService
meteorologist Nick Zacher said.
STRONG WINDS: #SH2 Rimutaka Hill. Please #TakeExtraCare, especially if you are in a high-sided vehicle or on a motorcycle. ^EL
HOT
START
The
stormy weather had seen the temperature in Dunedin at 20.2 degrees
Celsius just before 7am – less than a degree off the city's
forecast high of 21C for Monday – as warm unsettled conditions
flowed across from Australia. This contrasted with Invercargill,
further south, which recorded just 12.8C at the same time.
However
the temperature dropped sharply to 15C after winds turned
southerly at 8am on Monday.
MetService
meteorologist Michael O'Connor said the warm overnight temperatures
in much of the South Island east of the mountains were due to the
fohn effect, where northwesterly winds dump moisture and gain warmth
when passing over the Southern Alps.
When
the temperature peaked in Dunedin about 1am, there had been a kind of
tongue of warm air over the city.
About
7am, the warm air was working its way through Canterbury, O'Connor
said. Christchurch had got to near 20C.
Stormy
conditions were expected to continue in many areas throughout Monday
and into Tuesday.
About
5am Monday, the heaviest rain recorded was 56mm over the past
six hours in Milford Sound, Zacher said.
"Anywhere
from Greymouth southwards through to Fiordland is going to see a good
amount of rain throughout the next 48 hours," he said.
HIGH
WINDS
By
5am, a wind gust of around 215kmh had been recorded at Mt Hutt, with
140kmh at Castlepoint.
The
strongest wind recorded by MetService in Wellington overnight was a
108kmh gust in Kelburn at midnight, followed by a 99kmh gust at Mt
Kaukau.
The
northerly winds had eased off relatively on Monday morning but would
pick up again on Monday evening and night, when gusts up to 130kmh
were expected.
MetService
had a strong wind warning in place for Wellington until Tuesday.
Some
of the rain and thunderstorm activity was getting over the divide in
the South Island. "I wouldn't be surprised to see some thunder
and lightning and some heavy rain getting over the divide,"
Zacher said.
By
5am, the Otago headwaters and some areas to the south of Queenstown
were getting some decent spillover.
The
picture is different in the north of the country, with MetService
predicting just cloudy periods for Northland, Auckland and Bay of
Plenty on Monday.
For
the west from Waikato to Taihape, it's expected to be cloudy with
patchy drizzle turning to rain by tonight. In the southeast of the
North Island, scattered rain is expected to develop in Wairarapa in
the afternoon, spreading to Hawke's Bay by evening.
Severe
gale northwesterlies are expected to continue in exposed parts of
Wairarapa during Monday.
Wellington
is forecast to have rain with severe gale northwesterlies, as
are Nelson and Marlborough, although the severe gales are only
expected in the Sounds.
From
Canterbury to Southland it is expected to be dry on Monday, but the
severe gale northwesterlies are only expected to ease gradually.
The
temperature is expected to get to 20C in Auckland on Monday, as the
morning cloud breaks, giving way to a fine day. It looks like the
country's biggest city will get rain on Tuesday.
Wellington
is forecast to get to 15C on Monday, with northwesterlies gusting to
120kmh in exposed places and rain. Conditions are expected to be
similar on Tuesday, although improving later in the day.
The
NZ Transport Agency is warning of strong winds on State Highway 2
over the Rimutaka Range, north of Wellington.
Christchurch
could have a few spots of rain, with strong northwesterlies and a
high of 23C. Napier is forecast to get to 25C with a fine day,
although showers are possible from evening, and northwesterlies will
strengthen.
It's
only September but more rain has fallen in three of the country's
main centres than normally does in an entire year.
MetService
meteorologist Georgina Griffiths said given there was another week of
wet weather on the way, even more places would exceed their annual
norm by the beginning of October.
That's
bad news for Kiwis who were hoping the start of daylight saving today
would herald the arrival of an extra hour's sunshine for over the
next few weeks.
While
much of the country was expected to enjoy the remnants of a heatwave
heading our way from across the Tasman over the next couple of days,
the big wet is expected to return soon after.
After
a relative lull in the wind on Monday morning, MetService is warning
the worst of the wind is still to come.
Police
said a tree had blown over and was blocking a lane of Manchester St,
behind Wellington Zoo, on Monday morning.
The
strongest wind recorded by MetService in Wellington overnight was a
108kmh gust in Kelburn at midnight, followed by a 99kmh gust at Mt
Kaukau
Where is this warm, wet and windy weather coming from?
Warm air over Australia has picked up a lot of moisture as it crosses the Tasman Sea, and is bringing that humid air to New Zealand. That means heavy rain in the west, with rain warnings issued from Taranaki to the West Coast, and northwesterly gales for central parts. Seehttp://bit.ly/AllWarnings
for more info.
Humid northwesterlies also mean foehn heating in the east, caused by the air rising over the mountains (see https://www.youtube.com/watch?v=-Zshykr5NFQ). Fairlie hit 23.5C at 5am, nearly 3 degrees warmer than Niue airport at the same time. Other places were more fickle, with the northwesterlies cutting in and out, leading to rising and falling temperatures. But the nor'wester is more likely to reach the ground during the day, and today's highs are expected to reach 25C in Napier and 24C in Christchurch. ^TA
