Tropical Cyclone RUBY forms in Coral Sea: New Caledonia, Vanuatu & New Zealand in tracking (+4 Maps)

Updated 8:26pm Sunday — Australian forecasters have named the storm in the Coral Sea “Ruby” after reaching tropical cyclone status on Sunday afternoon.

The storm may strengthen to “severe” Category 3 Tropical Cyclone status with destructive winds. However low pressure zones in the New Zealand and Tasman Sea areas will siphon some energy from this tropical storm, helping to create an ‘atmospheric river’ over parts of New Zealand this week. This is when a highway of tropical moisture is funnelled into a narrow area over a period of time, increasing the risks of flooding.

We have more details here about how the lows this week will complicate the future of the cyclone as it gets closer to New Zealand and rain may be more of an issue than wind.

Latest modelling shows the remnants of the cyclone tracking very close to East Cape on Thursday night or Friday. However the other low pressure zones in the NZ area already are likely to trigger a burst of wind and heavy rain two days earlier, around Tuesday and Wednesday.
