Australian forecasters have named the storm in the Coral Sea “Ruby” after reaching tropical cyclone status on Sunday afternoon.

Having formed in the Coral Sea, it is currently a Category 2 travelling south west at the rate of 20kmph with winds of 110kmph and gusts of up to 170kmph at its centre, however, it is expected to intensify into a Category 3 later today.

It was forecast to hit the northern parts of New Caledonia last night and continue to move over New Caledonia today.

New Caledonia authorities say RUBY is forecast to move close to the eastern coast of Grande Terre, the Capital of New Caledonia, and then it is expected to pass over the Loyalty Islands around midday of 14 December.

Local authorities have initiated preventive operations ahead of the arrival of RUBY, while flights and maritime transport across the islands in New Caledonia have been cancelled.

Both the Australian and US tracking systems has the first cyclone of the 2021 season heading towards New Zealand.

Weather Watch NZ states, “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”.
