Weather warning: Storms, deluges, gales to slam top of New Zealand in next 24 hours

Brace for another wild weather day, with the top half of the country in for another bout of fierce winds and intense rain that threaten more floods and slips.

Northland, Auckland and Coromandel Peninsula are in line for gales while heavy rain is set from Northland to Gisborne.

And unusually high king tides have Coromandel authorities on notice with the eastern coastline under a flood watch this evening and tomorrow morning.

A road snowfall warning is also in place for the Desert Rd, with up to 5cm of snow expected to settle near the summit overnight.

What's happening today?

Another area of low pressure brings more rain to already very wet parts in the north of the North Island.

Southerly winds keep a steady feed of showers into Southland, Clutha and Dunedin.

Rain watches cover Auckland and eastern regions to Gisborne, starting this afternoon.

On the Coromandel the district council is warning that rain will coincide with higher-than-normal king tides at 7.30pm and 8am tomorrow.

"This combination means that surface flooding is very likely and slips/debris will continue to come down," advised the Thames-Coromandel District Council.

Meanwhile a section of SH25 remains closed by a slip with motorists travelling in the holiday hotspot warned to expect twice the volume of traffic and trucks on alternate routes.

"Please be extremely careful if you're travelling around the Coromandel, especially on these arterial routes that are being used as main thoroughfares because of the Wharekaho slip."

REMINDER: Due to a large slip, SH25 remains closed between Wharekaho & Kuaotunu as major works continue. The road is expected to re-open this evening (Thu 14 Jul). Delay your journey or consider a detour via Coromandel. https://t.co/MbnrF0XYlR. ^MF pic.twitter.com/iPYrxa3nQY

The incoming deluge is the latest storm to hit in an unusually unsettled fortnight, bringing even more rain to already very wet regions at the top of the North Island.

Many centres across the country have already exceeded their average July rainfall in the first 14 days.

MetService warns there will be intense downpours and the watch may be upgraded to warning level.

More rain incoming 🌧️

Another low will drop down into the northern & eastern North Island later Thursday into Friday, dropping more rain onto sodden grounds & swollen rivers.

A strong wind watch has been issued for Northland to Coromandel Peninsula, with gales buffeting northern regions throughout the coming night.

It comes soon after Tuesday's storm that swept across the country bringing destructive wild winds, flooding and snow to the South Island.

Weatherwatch.co.nz says over the past few days the Mackenzie region has seen some of the largest snowfall for years.

It's estimated that more than half a metre of snow has fallen around Mt Cook village and Tekapo, and 20cm for Twizel.

A months worth of rain, and we're not even half way though 🌧😯

Another low pressure system will bring further rain to northern regions tomorrow.
