Weather Video: Detailed update on Tropical Cyclones Pam & Nathan


Cyclone Pam is expected to deepen into a severe storm just north of New Zealand with incredibly low air pressure. We are monitoring all the various computer models to find the most likely path. In today’s video we update you on the likely movements of Pam as cyclone moves towards our north east on Sunday and Monday. We also update you on Nathan – the newly named cyclone near northern Queensland.

Cyclone

Hi. We are leaving on mon 16th from syd to Wellington for cruise of South Island voyager of the seas. Should I be worried ??

Cyclone

Wellington wont be any windier than it normally is. The cyclone is passing well to the east  so you should be good to go.

Warm centre vs. Cold centre?

Hi guys,

 

Would you be interested in writing an article that expands on the difference between a warm centre storm and and a cold centre storm, and how they generate their energy differently?

Hi Kieran, basically they

Hi Kieran, basically they both produce similar weather but the energy is spread in different ways.  In the tropics they are fuelled by warm waters and warm air, the storms spin very fast in ideal conditions.  This is why they get that perfectly round centre - the faster it spins the tighter it forms.  Once they reach NZ they run out of warm air/water, and the structure changes to support colder air storms - so you'll see as the cyclone reaches NZ and moves out to our SE it will start this transition - and will stretch out, spreading the energy much further but not being so central focused.  The weather is so much more chaotic around NZ, much stronger air currents around the poles tear the storms into new shapes and formations.  Here's some technical info: http://www.atmos.illinois.edu/~snodgrss/Midlatitude_cyclone.html

Will be watching the animals closely....

it has been said that prior to extreme weather all the wildlife dissapear to seek shleter as their "sixth sense" kicks in!  So will be observing the birds, ants and hedgehogs lol - as well, of course as your excellent updates!!

 

Cyclone Nathan and another Cyclone ????

Hey  i   want   to  know   if    Cyclone    Nathan    will   make  it   to   the   Pacific  Islands   like   Fiji   and    here 

in   NZ  .  

I  found  a  article   today   from    Fiji   Met Service   ,  they   said   that   in  next  few   weeks   of  March  ,  there  is  possibility  of   another  Cyclone  .

So  i   wanted   to   know   is   this    correct   cause    i   dont    really   trust   Fiji  MetService   they  often    give  out  wrong   predictions  .

Thanks

Hi there - yes there is some

Hi there - yes there is some chance of a third cyclone after Nathan, however all the current models suggest it's not looking too major (at this stage). Keep an eye on Australia's Bureau of Meteorology too, their Coral Sea outlooks and trackings are very good.

Pam

I see the lastest release of the Metservice 5 day rain maps show the cyclone's centre coming ashore in the Bay of Plenty Sunday / early Monday morning. What do you make of this prediction?

Hi there, Thanks for your

Hi there, 
Thanks for your question - and fair enough too! A few models (including our own here at WeatherWatch.co.nz - which are made from a combination of data out of the US Govt & here in NZ from MetOcean/Weathermap) are now picking the storm to move closer to us, but as Phil says in the video there are several models, and a couple others also show it still east of the country.  Last Friday the models were showing a direct hit to the upper North Island - then they all moved it well east...now the models are correcting a bit and pulling it back towards NZ. But with other models still suggesting it may pull east it's still just a little too early to lock it in and sound the alarms. By Thursday PM, or at the very latest Friday afternoon, we think we'll have a pretty sure idea as to how close it will get.  Certainly Gisborne and East Cape are high risk, as is eastern BOP and northern Hawkes Bay.  We're not willing to add other regions just yet.

We'll have another video update on Thursday, early afternoon. And on Friday afternoon we hope to have our most detailed update yet covering a few models and charts, we'll also put the one MetService map in there too, they will often pick one of the international models and go with that (like GFS or ECMWF), but with cyclones especially you should never ever trust just one model/map.

Cheers

cyclone

some times droughts end with a BANG..... just like 1958 when hamilton i think flooded after a drought

we need that cyclone

We have had only 70 mils of rain this year which is giving  the 2013 drought a run for its money.......its ok for you who have had thunderstorms for it to by pass us but for those of us who didnt get them this is vital

It will make an interesting

It will make an interesting start to the volvo ocean race leg leaving Auckland.

  Please, please, Please!!

 

Please,
please, Please!! find a new host for all your videos, I have not been able to
view them since you made the change, I have updated my browser and everything.
I also find the videos very laggy as well.

Hi there, what operating

Hi there, what operating system are you using - and what browser (ie, Windows, Google Chrome), we'll see if we can figure out why you're having problems viewing. The NZ Herald hosts these videos on a server out of the US, and our rural videos via CountryTV are hosted by YouTube.

Videos

I cannot watch videos on any of my mobile android devices as support for flash has been dropped, apparently because of security risks with flash? I understand that HTML 5 is the preferred format for video on the web but web developers need to adjust their content to this new format. In the meantime, flash content is not and never will be viewable on newer android devices.
