Special Video: A new cyclone forms & a southerly blast develops for NZ

This week is an exceptionally busy weather week around the New Zealand area with a tropical cyclone (Keni) which may bring severe weather to Fiji in the coming day or two but then may merge to create an especially large low pressure system to the east of the country.

Most regions have a few more warm days ahead of them but a cold change arrives in Southland this weekend and then spreads nationwide next week.

It will bring a big drop in temperatures, over 10 degrees down for some regions compared to the afternoon highs of this week.

A westerly airflow across New Zealand today will encourage more late summer-like temperatures in the east of both islands, mainly the North Island.

Two tropical cyclones are to the north of New Zealand, 1 a number storm directly north of us called Josie and the other is Iris in the Coral Sea which Australians renamed over the weekend.

We're in the peak of the Southern Hemisphere cyclone season with three active tropical cyclones affecting the Australian area alone this week and more on the way for the zone north of New Zealand.


Cyclone Iris forms near Vanuatu, may not move far in a week (+3 Maps)

Tropical Cyclone Iris has today formed just west of Vanuatu and while not a major storm the tropical low pressure system may linger in the Vanuatu / New Caledonia area for a full week, potentially longer.

The tropics are very active with three storm areas to focus on including one which may impact New Zealand at Easter (although too early to lock in and doesn’t look as strong as previous storms - but one to watch).

Weather Video: Southerly and cold front moves up New Zealand

A colder change is moving up the South Island and lower North Island today, dropping daytime temperatures by as much as 8 degrees below normal.

Rain or showers will move into the North Island over the next couple of days. By next week the Autumn weather pattern continues with a mix of highs, lows and cold fronts.


Heavy downpours, isolated thunderstorms possible for parts of NZ next few days (+4 Maps)

A cold front with a broad band of rain will move to the North Island from today and bring showers and
even some isolated thunderstorms. Because of a large high pressure parked to the east, a low has formed off the west
coast and will stay for next few days, causing unstable conditions mainly to the northern and central North
Island.
