    According to the latest forecast from the US Navy and Airforce Joint Typhoon Warning Center Cyclone Wati - which had been following in the footsteps of Cyclone Larry towards the Queensland coast - is about to make a 300 degree turn to the left and head for New Zealand's northern tip.

    While it is unlikely to pack cyclone force winds by the time it reaches New Zealand it would most probably bring sustained damaging gale force winds and torrential rain.

    Recent Satellite Image of Cyclone Wati off the Queensland Coast

    A forecast from the NOAA Global weather computer model ( see below) shows the cyclone grazing the northern tip of Northland early this coming Monday. The tightly bunched isobars indicate gale force winds from Northland to the Waikato initially spreading as far South as Wellington during the day on Monday.

    While at this range cyclone behaviour remains highly unpredictable the liklihood of New Zealand being adversely affected by Cyclone Wati appears to be fairly high.



    The first forecast in the series below is "+ 96 Hours 18hrs 26 March UTC " which corresponds to 6am Monday March 27 NZT. Each image shows 1milibar pressure gradients and forecast rain over a six hour period in coloured lines.
