New Zealand: Adverse weather forecast across parts of central regions through at least Dec. 7
Adverse weather forecast across parts of central New Zealand, through at least Dec. 7. Disruptions ongoing.
Event
Heavy rains are forecast in parts of southern Manawatu-Wanganui, northern Marlborough, western Taranaki, and Wellington regions through at least Dec. 7. The New Zealand National Meteorological Service has issued the following watches and warnings:
Orange Heavy Rain Warning (second-highest level on a three-tier scale): Mount Taranaki, Tararua Range, Kapiti, Horowhenua, Marlborough north of Blenheim, and Wellington; the heaviest rain is forecast at Mount Taranaki with another 10-14 cm (4-5.5 inches) of rain likely to accumulate.
Heavy Rain Watch: Wairarapa south of Greytown.
Authorities may issue new alerts or update/rescind existing advisories as weather conditions change over the coming days. Officials are advising residents in the Kapiti Coast to stay home.
Transport
Floodwaters and debris flows may render some bridges, rail networks, or roadways impassable, impacting overland travel in and around affected areas. Ponding on road surfaces could cause hazardous driving conditions on regional highways. Authorities could temporarily close some low-lying routes that become inundated by floodwaters. Reports indicate flooding on Airlie Road in Plimmerton, north of Wellington, and streets in Porirua. Authorities have advised that only residents can access the roads in the gorge section in Takarau Gorge due to flooding of the river. Mantell and Burnham streets in Seatoun and Maungakotukutuku Road in Kapiti are closed due to flooding and landslide. The disruptive weather may cause some delays and cancellations at regional airports. Authorities may temporarily suspend port operations if strong winds trigger hazardous sea conditions, impacting freight and passenger maritime traffic. Flooding could block regional rail lines; freight cancellations are possible in areas that see heavy rainfall and potential track blockages. Authorities have suspended trains along the Johnsonville line between Khandallah and Johnsonville due to a landslide.
Disruptions triggered by inclement weather and resultant hazards, such as flooding, could persist well after conditions have improved - it could take days before any floodwaters recede and/or officials clear debris. If there is severe damage to infrastructure, repair or reconstruction efforts may result in residual disruptions.
Advice
Monitor local media for weather updates and related advisories. Confirm all transport reservations and business appointments before travel. Make allowances for localized travel delays and potential supply chain disruptions where severe weather has occurred. Charge battery-powered devices in case of prolonged electricity outages.
