Further heavy rain expected for Tasman - CIVIL DEFENCE NOT ACTIVATED YET

 TASMAN HEAVY RAIN - Civil Defence Emergency Management Group Not yet Activated 

Tasman Bay

Tasman District Council is keeping a cautious eye on the next phase of severe weather approaching the region. 

Metservice has updated its weather forecast for Nelson and Tasman on Friday, with the area west of Motueka expected to experience 150 to 250mm of rain to accumulate about the ranges, and 60 to 100mm near the coast from midday Friday to 3am Saturday, in addition to what has already fallen. 

Peak rates of 15 to 25mm/h about the ranges, and up to 35mm/hr, are anticipated.  

Bryant Ranges

Council is also keeping an eye on what rainfall occurs around the Richmond and Bryant Ranges as well as the Nelson Lakes areas, particularly in relation to rising river levels. 

Between 150mm and 230mm of rain is expected to accumulate from 1pm Friday to 11am Saturday, in addition to what has already fallen, with peak rates of 10mm to 25mm/h. 

Richmond Ranges Saturday Morning 5th Feb

Staff were made aware of several minor slips in the district overnight, as well as pooling of water near Pōhara and on properties near the Tākaka River. However, no road closures were necessary. 

The Nelson Tasman Civil Defence Emergency Management Group was yet to activate the Emergency Operations Centre (EOC) as of 2pm on Friday but were monitoring the situation as it developed.

The Aorere, Anatoki and Tākaka areas of Golden Bay have received between 229mm and 433mm in the last two days.   

Rivers in Golden Bay have receded thanks to a brief pause in rainfall on Friday but will again rise this evening with the forecast rain expected to see slightly higher flows than Thursday, peaking later tonight and early Saturday morning.   

River flows occurring so far have not caused any issues, and this should remain the case with subsequent flows to come.     

However, with the saturation already seen in Golden Bay, and also in the hills behind Richmond and Nelson, we remain cautious that any unexpected high intensities could cause flooding higher than predicted levels.

As the event proceeds, there are also likely to be some slips and surface flooding.

Westport - A well organised evacuation

Buller River Westport

Today the evacuation began in Westport and the Mayor Jamie Cleine gave an update on the current situation.

Buller district mayor Jamie Cleine said “heavy rain is expected to pass through overnight and ease to just passing showers by tomorrow afternoon.” 

Buller Emergency Management

“The Westport community are all doing a fantastic job of evacuating.

281 houses have been visited by Police, Fire and Emergency, Westport Land Search and Rescue and our volunteers and already over 158 households have evacuated.” 

Helicopters are assisting the medically vulnerable to get out of evacuation areas. He believes we are all getting through this together. 

He thanked the community for moving swiftly and wanted them to keep safe.

Westport

He is “comfortable that they have evacuated enough of Westport for the present event and that evacuations are now just about complete.

There were many residents who self evacuated 48-24 hours ago when Buller Emergency Management suggested that people should start evacuating. A significant number of people made the move.

“Messaging has been going out for about 2 days for people to evacuate as they had a good idea that there was going to be a flood.”

Help came from all over the South Island

There has been very good forward planning and modelling with help from the MetService. Modelling suggested the Buller River would rise to a similar level as the 2021 event, "so slightly less than the July flood at this stage”.

Westport

There has been some resistance from some residents to evacuate but he said “they don’t want them to become a rescue situation in the middle of the night.”

The Buller Emergency Management have a full evacuation plan right down to a full list of streets that would need to be evacuated.

The Army was there to help

“The river is being monitored and it should be at its highest at 2.30 am Saturday tomorrow.”

The Prime Minister will be in Westport tomorrow and the Government has provided everything that Westport needs.

“The community have learnt well from the July event and have acted well today.”

Sandbags Westport

“Emergency Services have come from all over the South Island to help. Due to the proactive start to this event by the Buller Emergency Management and media, the public have been well informed.”

The community knew what to do as many prepared themselves to evacuate like turning off the power, water and gas which made it safer for authorities and utilities in the area.

Westport

“People have been told to be prepared to evacuate for three days. At 3pm Friday, officials reassessed the situation and were comfortable enough that Westport had been evacuated enough,” Cleine said.

“Anyone outside the evacuated areas who felt unsafe could choose to leave too, and anyone who could not stay with friends or family could stay at a welfare centre set up at the old Holcim cement site near Cape Foulwind” Buller Emergency Management said.

Buller

Road closure updates Buller:

• State Highway 67 between Waimangaroa to Birchfield is closed due to impassable surface water.

• Bulls Road has surface water. Drive carefully. 

• Derby Street to Domett Street is closed due to surface water.

• Denniston Road is one lane and caution needs to be taken due slumps on the third corner up.

Boil Water Notice for Eighty-Eight Valley Supply

 

BOIL WATER NOTICE TASMAN DISTRICT COUNCIL

04 February 2022

Tasman District Council has issued a boil water notice for residents connected to the Eighty-Eight Valley water supply south of Richmond. 

Heavy rain has increased turbidity in the water that supplies the valley’s water treatment plant making it potentially unsafe, so as a precaution a Boil Water Notice has been issued. 

Residents are also being asked to conserve water wherever possible to limit the amount of dirty water that is drawn into their storage tanks and pipes. 

 

EIGHTY EIGHTY VALLEY WATER SUPPLY SOUTH OF RICHMOND  BOIL WATER 

People should boil all water used for: 

• Drinking  
• Food preparation 
• Mixing cold beverages 
• Utensil washing and food preparation 
• Brushing your teeth 
• Pets 
• Ice making 

Water should be brought to a rolling boil (where bubbles appear in the center and do not disappear when the water is stirred) for one minute or boil a full electric jug until it switches off. 

Cool the water (do not use ice cubes to do this) and pour into clean container with a lid and refrigerate until needed. 

It is likely that the boil water notice will be in place until Tuesday 8 February but will be dependent on how quickly the source water recovers from the current rainfall event. Updated information will be posted on the council website, Facebook page and Twitter. 

Please note that nearly all household filters provide no protection against bacterial contamination. If you have an under the sink carbon filter or cartridge filter, you still need to boil your water. 

For further information please call the Council on 03 543 8400.

With the increase in rainfall totals for the Richmond Ranges by Saturday, flows in the eastern rivers may exceed annual flood levels, but major flooding is still not forecast. 

Driving conditions may also be hazardous, so please drive to the conditions and allow extra time to get to your destination. 

If not done already, residents are being reminded to make sure drain areas are clear of debris and stock should be moved away from river flats. 

Rivers are rising. Buller District Council

There is the potential for some coastal erosion during high tides, but no coastal inundation of significance. 

Rain is expected to ease for a time Friday morning. However, further rain is possible Saturday night and Sunday and a new heavy rain watch or warning may be issued closer to the event.

Red Weather Warning - West Coast Evacuations

Buller Emergency Management Centre

The West Coast is in emergency mode due to the Red severe weather warning with the West Coast DHB prepared for and monitoring the expected impact of the current severe weather event.

In Buller, the majority of residents at O’Conor Rest Home have been evacuated yesterday to alternative accommodation – some have gone to stay with family, a handful to a facility in Nelson-Marlborough, some down to Te Nikau in Greymouth and the majority are now on their way to Christchurch. There are some residents still at O’Conor Rest Home who will be evacuated today.

Four hours ago the West Coast Emergency Management advised the public to be ready today in case you have to evacuate. Have your grab bags handy, connect with friends and family, assist your neighbours to get ready, and make sure your car is good to go to take you to higher ground. 

The Buller Emergency Management have updated the forecast for today and the next few days for Westport. More rain is set to come through Friday and into Saturday morning.  

A half an hour ago the advised “Buller Emergency Operations Centre is working to make arrangements for any mandatory evacuations if required in the next few days. This includes arranging evacuation centres for residents if or when required.”

  “In the meantime, we are asking residents to self-evacuate if they can easily do so to friends and family OUTSIDE OF WESTPORT.”

“The Coast Road and Gorge are still open, so moving East and South out of town are still safe options.” 

“Self-evacuation is encouraged for those who experienced flooding in July last year as a precaution.”

  

“Further evacuation decisions will be made as we get more clarity around rainfall in the next 24 hours.”

The West Coast Emergency Management Centre have outlined the road closures and warnings: 

SH 6 Fox Glacier to Haast, Road closed due to flooding update 12 pm 3rd Feb

SH 6 Haast Pass, Road closed due to flooding update 12pm 3rd Feb

Road Warnings

SH 6 Hokitika to Fox Glacier, Area Warning due to Surface water as the result of heavy rain. More heavy rain forecast. Slow down

SH 67 Westport to Mokihinu, Area Warning due to Surface water due to heavy rain. Slow down

The WCEM advise that “rainfall intensities are beginning to ease but rain is continuing to fall.  The Haast River, Waiho River in Franz Josef and Hokitiki Rivers in Westland continue to be monitored very closely.”

  

“Rivers levels throughout the West Coast Region are being monitoring by flood teams as further rise is predicted as rain continues. The Metservice are predicting ongoing rain, although intensities may ease through Thursday in Westland but are expected to continue from midday Thursday, with heavy falls on Friday.”  

For Buller, further rain is likely overnight Thursday, Friday and Saturday morning, and this Warning could be extended.

West Coast Regional Emergency Control Centre (ECC) Controller Trevor Watt has urged “all West Coast Westland Residents to remain prepared for further rain and rising rivers.  Do not take unnecessary risks around rivers and streams and please limit unnecessary travel due to surface flooding and slips.”
