More heavy rain is forecast for Buller days after floods devastated the region.
MetService has issued a heavy rain warning for Buller and the Westland for an 11-hour period, starting from 6:00 p.m. Wednesday to 5:00 a.m. Thursday. It comes as residents begin to assess the damage from the severe flooding over the weekend that displaced hundreds of people.
MetService meteorologist Tui McInnes said the region can expect showers Wednesday morning, turning into rain in the evening when the warning “goes into effect.”
Only 40-60mm of rain was forecast, which McInnes said would not normally lead to a heavy rain warning, but due to significant rainfall over the weekend, the warning was issued.
Thunderstorms were also forecast in localized areas that could bring more rain during peak hours, up to 15-20mm in an hour, he said.
Donation Drive was set up by Samara File and her husband to help people get back on their feet after flooding in Westport.
A heavy rain warning was normally issued when 50mm of rain was expected over a 6 hour period, or 100mm in 24 hours.
Buller mayor Jamie Cleine said the warning was being watched but was not concerned.
“It’s probably a few days of wet weather, which clearly isn’t helping people trying to clear out their belongings.”
Rain was expected to continue in Buller on Thursday, but to ease over the course of the day and into Friday.
The west coast would be hardest hit by the predicted rain, but the frontal system was expected to move across the country throughout Wednesday, McInnes said.
“Most areas will experience some wet weather.”
East of the mountain ranges would be drier on both the North and South Islands, while the western areas would be more exposed, he said.
At 3pm on Sunday, 158mm of rain had fallen in Westport while Reefton, in the Buller outback, received 168mm of rain. Weather stations higher up in the mountain ranges, towards Murchison and Nelson Lakes National Park, recorded more than 300mm for 60 hours.
