Cyclone Fili remains around New Caledonia today, as a Category 2 tropical cyclone at the time we recorded this.
Meanwhile NZ has a southerly change moving up the country with showers.
While Fili may lose tropical cyclone status this weekend, it may then become extra-tropical (which can make it stormier again as it tracks past NZ).
Next Tuesday and Wednesday there are some severe weather risks for the North Island.

Strengthening when entering cold water? I thought the opposite was usually the case? Thanks

Cold water kills off/weakens the Tropical portion of the cyclone (warm air in the core of the storm). But, the low can then change and once it becomes extra-tropical the storm then can grow in shape and become even larger (usually not as intense at the centre like a tropical storm). So yes, you’re correct – but then they turn into a ‘cold core’ storm like the ones in the Southern Ocean and they can be quite nasty. This transition usually occurs in the NZ area.
