Aucklanders have been warned that two months鈥 worth of rain could fall in some parts of the region today and police have advised motorists to reconsider travel plans due to slips and heavy rain.

Severe thunderstorm watches have been issued for southern Northland, Auckland, and Coromandel for this afternoon and evening and until midnight.

Rain rates of 40mm in an hour have already been reported in parts of Auckland.

Auckland Emergency Management issued an Emergency Mobile Alert at 5.11pm due to the heightened risk of further landslides and flash flooding in Bethells Beach, Karekare, Muriwai and Piha.

鈥淭he alert has been issued due to an active line of thunderstorms which has brought high intensity, localised downpours,鈥 EMA said.

Earlier, WeatherWatch posted a message on Twitter that 鈥渙ne or two months鈥 worth of rain is going to fall in some places today (& already has done north of the city in rural areas)鈥.

Niwa meteorologist Ben Noll said a cold front that had been moving north had 鈥渟talled out鈥 over Auckland, 鈥渁nd that鈥檚 going to act as a focal point for the development of heavy showers鈥.

鈥淎uckland and Coromandel are certainly going to be under the gun here 鈥 and we鈥檙e concerned with the timing of this heavy rain coinciding with the afternoon and evening commute,鈥 he said.

鈥淚f this rain continues into the night, then that timing may feel a bit like d茅j脿 vu, given the event we had a couple of weeks ago."

While that didn鈥檛 mean this storm system was a repeat of the historic January 27 deluge, Noll said it nonetheless came with some red flags.

鈥淲e鈥檝e got a cold front that鈥檚 moved up the country, and a convergence zone draped across Auckland,鈥 he said.

鈥淣ow, this is a bit different to what we had a couple of weeks back 鈥 which was basically a big subtropical low that brought down heaps of subtropical moisture.

Piha Surf Lifesaving Club custodian Paul Newnham said it had been 鈥渂ucketing down鈥 in the west coast settlement for about two hours.

鈥滻t鈥檚 not terrible but it鈥檚 a good, solid bit of rain.鈥

Another Piha resident said it was coming down steadily with small periods of heavy rain.

鈥漀orth Piha is starting to fill up again. I think it鈥檚 quite dangerous already. If the rain continues with no breaks, I鈥檓 not sure what might happen.鈥

鈥淭hat was a lot more widespread in terms of its coverage, whereas this is a much more localised phenomenon.

鈥淏ut, considering we鈥檙e dealing with convection - which is equally as challenging to predict in terms of its exact placement - the bottom line is Auckland needs to be aware of this possibility [of severe weather] later today and tonight.鈥

Locals in the Mangawhai area reported some of the 鈥渉eaviest rain they have ever seen鈥 on social media as more wet weather batters the area.

Multiple main roads are now flooded after just an hour of rain, with people describing it as 鈥渞ising rapidly鈥. Another local reported seeing emergency services helping those who are stranded.

Heavy rain north of Auckland closed State Highway 1 at the intersection of Kaiwaka-Mangawhai Rd, and also to the east in Hakaru.

鈥淒ue to slips and flooding, SH1 Waipu to Brynderwyn detour via Kaiwaka-Mangawhai Rd is closed,鈥 Waka Kotahi NZTA reported.

Aucklanders are being advised to take extra care if travelling around the Auckland region this evening, with MetService weather warnings and watches in place across the region.

Roads damaged during Cyclone Gabrielle and the anniversary weekend floods remain especially vulnerable to the impacts of further rain.

There are currently full closures in place for 25 roads across the Auckland region, and there is a risk of further closures depending on the severity of today鈥檚 rainfall.

鈥淲e are asking Aucklanders to be especially careful if travelling in areas hardest hit by the recent weather events, particularly in the Waitakere Ranges, rural Rodney and Awhitu Peninsula.

鈥漌e do not expect any significant disruption to public transport services as a result of the weather this evening. As a precaution we have reminded bus drivers to put safety first and avoid driving through floodwater, should flooding occur.鈥

Due to weather conditions, some West Harbour Ferry services have been cancelled in Auckland.

Police also warned motorists to consider changing their travel plans following reports of multiple slips and flooding in Waitemat膩 North this afternoon.

Due to heavy rain, a number of roads have been affected by slips and flooding in Mangawhai, Mahurangi East, South Head, and Topuni, police said.

Police urged motorists to avoid non-essential travel if possible and to check updates for the latest weather forecast for their area.

Early this afternoon, MetService issued a heavy rain and 鈥渟evere鈥 thunderstorm watch for most of Auckland this afternoon until 10pm tonight.

A severe thunderstorm warning has also been issued for Kaipara and Rodney.

40 homes evacuated in Esk Valley region

Meanwhile, up to 40 homes in Napier鈥檚 Esk Valley have been evacuated today as more heavy rain closes in on the cyclone-ravaged region.

鈥淗eavy rain is expected to cause impacts tonight, and you must evacuate now so you can move during daylight while it is safe to do so,鈥 Civil Defence posted on social media.

Emergency services are carrying out a sweep through the area to make sure everyone was safely out, Hawke鈥檚 Bay Emergency Management group controller Ian Macdonald said.

鈥淭he river is known to rise quickly and it is known to burst its banks so we are trying to make sure people are safe tonight.鈥

An estimated 100-150mm of rain is expected to fall between this afternoon and tomorrow morning.

North Island regions still battered and soaked by Cyclone Gabrielle are facing fresh warnings of heavy rain, prompting concerns for vulnerable communities which are yet to recover.

And with more deluges also expected for hard-hit Gisborne and Hawke鈥檚 Bay from today, authorities aren鈥檛 taking any chances - warning residents to prepare for all eventualities.

Hastings Mayor Sandra Hazlehurst said she is concerned for Esk Valley, 鈥渙ur most vulnerable community鈥.

鈥漁ur community is traumatised, they鈥檝e seen a lot. They鈥檝e been through a huge cyclone a huge event that they鈥檝e never seen in Hawke鈥檚 Bay in their lifetime.鈥

She said she lay in bed last night listening to the police helicopter overhead and rain, waiting and hoping for it to stop.

鈥漈here are people out there feeling nervous and vulnerable.鈥

Napier Mayor Kirsten Wise told 九一星空无限talk ZB that she was 鈥渞eally conscious鈥 there will be a lot of anxious people in her community right now. Modelling predicted another 100-150ml of rain in the next 12 hours.

While the modelling did not show 鈥渟ignificant impacts鈥 for Napier, she said Esk Valley was an area of concern, hence why they were doing a 鈥渧ery precautionary evacuation鈥.

鈥漌e do know that the Esk will be getting that higher volume of rain so we just want to be super safe.鈥

A total of 23 people remain 鈥渦ncontactable鈥 in the Hawke鈥檚 Bay and Gisborne areas after the cyclone, police said today.

Prime Minister Chris Hipkins and Te Tai Tokerau MP Kelvin Davis are spending touring cyclone-ravaged Northland and meeting with local mayors today to survey the devastation caused by the severe storm.

Large slips have wreaked havoc across the region and State Highway 1 is still closed between Brynderwyn and Waipu due to slips, and is partially closed between Whangarei and Kawakawa.

Hipkins is scheduled to meet with community organisations, emergency response teams and observe the impact flooding has had on the area.

Hipkins was back in Hawke鈥檚 Bay yesterday, surveying the damage and announcing a ministerial inquiry into forestry slash, to be chaired by former National education minister and Gisborne-based MP Hekia Parata.

His planned flight to Wairoa to witness the destruction caused by Cyclone Gabrielle lasted all of 10 minutes before it had to be abandoned - with the weather at fault again.

Low cloud along the east coast meant the NH90 Hipkins was travelling in had to be redirected to the Napier airport shortly after takeoff from the Hawke鈥檚 Bay Showgrounds.

Hipkins told a media stand-up yesterday 鈥渢hings have to change because slash on beaches, in rivers, on farms is unacceptable鈥 - something he said he would take steps to address in the very early days after the cyclone smashed through the North Island.

Photos of collapsed bridges with piles of slash at their bases 鈥 and anger from those in places such as Tolaga Bay 鈥 reignited calls for action on the long-standing problem of debris from commercial forestry.

Napier MP and Small Business Minister Stuart Nash said: 鈥淲hat this [review] will do is make recommendations about how we can get this right. What we need to get right is the management practices of forestry on these highly erodible soils.鈥

He said the forest sector had done a lot of work in retiring certain forests, moving slash from skip sites, but the country had still seen a lot more wood coming on to the beaches.

Nash said he wanted the forestry industry to 鈥渢ake responsibility鈥 for its actions regarding slash.
