Computer Model Simulations Of Cyclone Wati's Path
The image above from the WeatherUnderground.com show that the US Navy's Nogaps model forecast is now close to agreement
with the NOAA GFS forecast. Both show the remnants of the cyclone coming close to New Zealand's North Island.
At present considerable uncertainty remains over the extent to which these remnants will dissipate as the cyclone bumps
up against a high forming in the southern Tasman Sea.

Joint Typhoon Warning Center Cyclone Wait Warning Graphic
The most recent Joint Typhoon Warning Center forecast - the graphic of which appears above - is forecasting the cyclone
to rapidly weaken over the coming 24 hours. Maximum sustained winds at the end of the period are forecast at 35 knots
near the bottom of the range for a tropical storm.
Earlier today the MetService issued a press release advising that: "The most likely scenario at this stage is that the whole system spreads out and a frontal system forms
that may bring significant northeast wind and rain to the northern North Island and maybe the northwest of the South
Island on Monday and Tuesday."
