South Island Faces Severe Weather: Winds, Power Cuts, and Risks

Severe weather has struck the South Island of New Zealand, bringing destructive winds and heavy rain that resulted in widespread power outages and significant travel disruptions. As of this morning, areas including Milford, Orari, Orton, and Temuka are experiencing unplanned power cuts, as reported by Alpine Energy. Crews are actively working to restore power, while residents are advised to treat all downed power lines as if they are live.

According to MetService, the strongest recorded wind gusts reached 110 km/h in Mount Cook. Authorities are urging motorists to avoid travel, particularly in Canterbury, where a red wind warning has been issued, indicating wind speeds could reach up to 150 km/h in exposed areas. The warning specifically highlights the Canterbury High Country, which is expected to face damaging northwesterly winds.

Impact on Transportation and Public Safety

The severe weather has prompted Waka Kotahi NZ Transport Agency to advise against travel in areas west of the foothills and south of the Rakaia River. In light of these conditions, KiwiRail has cancelled its Sunday TranzAlpine service, including the 7:45 am departure from Christchurch to Greymouth and the 2:15 pm return trip. No further cancellations have been announced at this time.

Fire authorities highlight the increased risk of wildfires due to high winds. Rob Hands, district commander for Fire and Emergency New Zealand, expressed concern over the challenges faced by firefighters in recent days due to high winds exacerbating existing fires. He urged residents to ensure that any outdoor fires from the past two weeks are completely extinguished.

Heavy Rain and Flooding Risks Ahead

In addition to the wind warnings, the South Island is under orange heavy rain alerts, with forecasts predicting between 100 mm and 140 mm of rain in the Tasman region northwest of Motueka within a 12-hour period starting from 9 am on Sunday. Similar warnings are in place for western parts of the South Island, including the headwaters of Canterbury and Otago lakes and rivers.

Areas such as Westland could see rainfall amounts ranging from 120 mm to 180 mm along with strong winds of up to 120 km/h. Authorities warn that rapid river and stream rises may lead to surface flooding, landslips, and further power outages.

Residents are advised to take precautions by securing loose items outdoors and preparing for potential travel delays. With school holidays currently underway, authorities emphasize the importance of driving cautiously and staying informed about weather updates.

As the South Island grapples with these adverse conditions, communities are encouraged to prioritize safety and remain vigilant as the situation develops.
