Weather Video: Cyclone Donna’s path towards NZ

Severe Cyclone Donna is passing New Caledonia over the next 24 hours before it tracks further south over cooler waters and weakens. However Donna is expected to remain a small but potent storm as it tracks into the New Zealand area on Friday, then it may pass to the east and rapidly deepen into a new system. Something we’ve called Donna Mark II.

Severe Cyclone Donna is heading towards New Zealand but a direct hit looks unlikely and the storm is going to weaken significantly before reaching northern areas.

However - it's what may happen to Donna AFTER she leaves the tropics that may have more of an impact on New Zealand.

Severe Cyclone Donna now Category 5, breaking historical global records

Severe Cyclone Donna, which and CNN reported Monday morning had reached Category 5 status, has Monday night finally been "officially" (Government endorsed) confirmed by the Fiji Metservice and NZ MetService.

Winds are sustained at 215km/h and gusting 260km/h, making Donna the strongest ever May cyclone recorded in the entire Southern Hemisphere.

Will Donna impact NZ? It's complicated!

Cyclone Donna's journey towards New Zealand looks more complicated than Cyclone Cook which is why we're still taking our timing working out how this might unfold.

Back to Cat 3 out at sea, Donna's turning towards New Caledonia

Severe Cyclone Donna is back to a Category 3 storm after being upgraded to a Category 4 storm overnight and earlier this morning. Despite the category changes the storm itself hasn't changed much, it's simply hovering around the threshold between these two categories used to measure the strength of a tropical cyclone.

The Fiji Met service says Donna's air pressure is now 960hPa.

Severe Cyclone Donna upgraded to a Category 4 tropical storm

Severe Cyclone Donna has been upgraded to a Category 4 tropical storm (the maximum is 5) as the low tracks further away from Vanuatu and into open waters.

Donna will still be tracking along Vanuatu's western side but further out to sea, which at this stage will limit severe weather in Vanuatu itself.
