Predictwind: Tracking Cyclone Lusi Update 2: Storm due late Friday

Tropical Cyclone Lusi is predicted to hit New Zealand, on late Friday night, and early Saturday morning. She is expected to bring strong winds and much needed rain to the top of the North Island.

Sail-World started tracking the storm at 2200hrs on Thursday night - the times of the shots of the storm can be read alongside each image. This update is from 2200hrs on Friday.

The first three Isobar images show the progress and expected track of the low pressure area from the Pacific at 2200hrs on Friday night, and again 24 hours later on Saturday night, and some from Sunday.

Predictwind produces two weather predictions based on two independent feeds and then applies various adjustments to take account of a variety of factors including land mass and topography. For a fuller explanation of how PredictWind enhances its feeds to provide a detailed local forecast click here

As we can see in these images, one projection expects the low to split a little as it hits the top of New Zealand, the other expects it to slide, unusually to the west of New Zealand. (Typically such Lows veer off to the east as the hit New Zealand and dissape in the Pacific, this is not expected to happen with Cyclone Lusi)

In this Forecast Table from Predictwind.com we can see the wind strength at two points - Mongonui in the far North and Bean Rock in the Waitemata Harbour.

The point of these two graphics is to show the winds predicted for Mongonui and then the times these will progress down to Auckland. They also show that the wind strength is predicted to top out at close 60kts in Auckland around 0700-0900hrs, on saturday morning, and that there will not be a lot of difference between Mongonui and Auckland - except that Mongonui gets the wind and rain ahead of Auckland.

The third graphic shows the real time weather observation points around the North Island, these points are used to track the actual wind strength and direction. When Lusia hits Cape Reinga, check the readings at the top of the North Island, compare these with the forecast tables and then check the variance between forecast and what is happening to the north, as that will track south to Auckland and beyond.

Real time observations - Bean Rock showing a more moderate breeze without much change in direction - ahead of the arrival of the low pressure zone - PredictWind March 14-15, 2014 - Cyclone Lusi, 2200hrs - 140314 -  PredictWind   Click Here to view large photo


The fourth set of graphics shows the advance of the rain, which will be heavy but is not expect to last that long, but will be replaced with strong winds
