SITUATION
Cyclone Vaianu is expected to move southwards across the North Island on Sunday, 12 April. The current track of the cyclone can be found at https://www.metservice.com/warnings/tropical-cyclone-activity. Great Barrier Island has been upgraded to a RED warning for wind. The combination of damaging winds, heavy rain and coastal inundation makes this a multi-hazard, potentially life-threatening event. The locations of the most severe impacts associated with Cyclone Vaianu, such as power outages, falling trees, flooding, slips, road closures and isolated communities are highly dependent on the cyclone's track. Strong Wind and Heavy Rain Watches and Warnings are in force for much of the North Island and upper South Island Sunday and early Monday.
