Rain continues in Nelson and Tasman as Heavy Rain Warning Turns Red

Heavy Rain Warning Red for Nelson

MetService have late this afternoon upgraded the weather forecast to a Red Warning from Cape Soucis, through Nelson City to Stock.

The expectation is for a further 250 to 400 mm of rain to accumulate on top of what has already fallen. Peak rates of 15 to 25 mm/h possible, especially until about 6pm Wednesday and again during Thursday morning.

This rain is expected to cause dangerous river conditions and significant flooding. Slips and floodwaters are likely to disrupt travel, making some roads impassable and possibly isolating communities.

If you live near the river from the Nile St Bridge to the Golf Course, please EVACUATE. Stay with friends and family if you are able. If you have no safe place to go, head to the Saxton Stadium .

People are being asked to stay with friends and family if you are able.

If people have no safe place to go, they should head to the Saxton Stadium where they will be able to gain assistance.

Mayor Reese says there are preparations underway to look after people who need to leave their homes and there will be trained people on hand to offer support.

People are being asked to take pets, essential medications and warm clothing.

Update from West Coast Emergency Management

West Coast Emergency Management

17 August 2022

Prepared and waiting

Agencies across the West Coast have spent the last several days preparing for the significant weather event currently affecting the West Coast, and across New Zealand.

The latest modelling is indicating an easing in event intensity around Westport.

For the Buller River, the forecast flow range has come down to 4000 – 6000 cumecs. This is a reduction from yesterday’s forecast flow of 5000 – 7200 cumecs.

While this event is still expected to bring significant flows to the Buller River, bank overtopping from the event is not expected, with flows similar to the first February event.

The peak flows will occur tomorrow, early morning for Te Kuha and mid-morning for Westport. The Orowaiti Overflow will receive flows after 4000 cumecs. The tide is slightly higher than what was experienced during the February event. This may increase river levels in the Snodgrass area.

Te Aroha Cook, West Coast Group Controller, said that observations will give confirmation of actual flows early tomorrow morning.

“For Westport, if you experienced flooding in February, or are feeling vulnerable due to proximity to the Orowaiti, you may want to consider self-evacuation. There may also be stormwater ponding, surface flooding and stopbank seepage. Self-evacuation includes making arrangements for pets and lifting valuables.”

Further south, Civil Defence and supporting agencies are still expecting rivers to rise in Westland. Peak rain intensities are expected from late Wednesday afternoon into Thursday.

“We are watching the Hokitika River closely. We know that it is currently high and more rain is expected. Peak flows are anticipated to coincide on a falling tide.”

Observations on the Wanganui and Waiho Rivers are ongoing through the event.

“As the freezing level continues to rise we can also expect increasing snow melt which will impact our river flows, particularly as we move south through the region.”

Stock and animals should be moved from low lying rural areas, including Snodgrass.

“Plan your journeys IF you need to go, but please just stay at home.”

POLICE CONFIRM - SH6 - ROCKS ROAD NELSON - CLOSED (Nelson Tasman Emergency Management Media Release)

SH6 ROCKS RD CLOSED

First signs of weather event emerge following overnight rain across Nelson Tasman

17 August, 2022

Police confirmed at 11.30 this morning 17 August that SH6 Rocks Road is closed following a slip this morning near Britannia Heights Nelson City. The Police advise to take an alternate route.

Main Road Stoke (Saxton to Sailsbury) will likely close soon and Maitai Road will close soon.

MEDIA RELEASE FROM NELSON TASMAN EMERGENCY MANAGEMENT

The anticipated heavy rain forecast appears to be coming to fruition across the Nelson Tasman region. Steady rain is setting in across Golden Bay, particularly in the Aorere Valley where between 22 and 29mm has fallen overnight, and more than 240mm in the last 30 hours.

The Aorere River just reached a level at which we can expect the Ferntown Road, near Collingwood, to be flooded this morning, although the current low tide may delay this slightly.

Other parts of Nelson Tasman have received low to moderate amounts of rain overnight – with less than 3mm overnight in Murchison and around Nelson City, while up to 18mm has fallen around Riuwaka.

Due to the likelihood of the Riuwaka River reaching significantly high levels today, peaking at around 3pm, residents in the vicinity of Cooks Corner were notified on Tuesday evening of potential flooding around their properties and to make plans accordingly.

The Nelson Tasman CDEM Emergency Operations Centre has been set up in monitoring mode this morning and we are expecting to become busier as the anticipated rain and wind descends on the area.

We would like to reiterate that the weather is expected to get worse in the next 24 hours. Please ensure you take all the necessary precautions to prepare for potential hazards to keep your property, yourself and your loved ones safe.

Surface flooding, slips and tree falls are likely, so please delay unnecessary travel, particularly in the Golden Bay area and avoid the urge to go sightseeing.

Takaka sewage pump stations are struggling to cope with volumes and there are overflows at some sites. These overflows contain raw sewage and people must avoid these areas

Surface flooding and slips have already begun to cause road closures in Golden Bay.

Collingwood-Puponga Road is closed by Whites Bridge, One Spec Road, Pohara Gully due to flooding. Wainui Hill is closed just north of Tata Beach due to slips. Abel Tasman Drive is open (up to the Wainui Hill) but has a lot of surface flooding

A surface flooding warning is also in place for SH60 Upper Takaka and Collingwood. The road remains open but please take extra care and drive to the conditions.
