Wild weather warning: Second cyclone of season may form next week

The season鈥檚 second tropical cyclone in the southwest Pacific could form up within days 鈥 but forecasters say it鈥檚 too early to tell what, if anything, this developing system may mean for New Zealand.

With the North Island鈥檚 East Coast still cleaning up Cyclone Hale鈥檚 mess, MetService鈥檚聽聽states a moderate risk 鈥 or a 20 to 50 per cent chance 鈥 of a system developing west of Vanuatu from Wednesday onwards.

It was expected to move eastward, across, or close to southern Vanuatu late next week.

鈥淲e鈥檙e not looking at this to start to form until around Wednesday, and if it heads down towards us, that鈥檚 still a long way off,鈥 MetService meteorologist John Law said.

The area of risk at this point was limited to around Vanuatu, with conditions in the Coral Sea expected to be favourable for forming cyclones over the next week.

鈥淚t鈥檚 a situation that we鈥檙e obviously going to be keeping a very close eye on, but at the moment, it looks like it鈥檚 going to be very far away.鈥

Niwa鈥檚 start-of-season outlook predicted a 鈥渘ormal or elevated鈥 risk of tropical cyclones between November and April, with the potential for one to two systems.

Each season - usually around late summer - at least one ex-tropical cyclone veers within 550km of the country, packing gale-force winds and enough moisture to drive torrential rain.

Hale鈥檚 visit last week was estimated to have caused millions of dollars in damage in Coromandel, while leaving beaches and waterways around the Tairawhiti region strewn with slash and debris.

For now, a ridge of high pressure sitting over the country was forecast to bring more hot, settled weather tomorrow, with 30C highs on the cards for Wanaka and Alexandra, Laws said.

By mid-week, MetService was forecasting isolated showers about both islands 鈥 and possibly more heavy rain for Gisborne.

鈥淭here is an area of low pressure that swings down toward northern and eastern parts of the country as we head toward the end of the week, which could potentially bring some wetter weather in places like the Coromandel, that have already seen a fair bit of it.鈥

鈥淚n the short-term, that鈥檚 our main concern.鈥
