Storm

New Zealand is particularly prone to storms as it lies in the 'Roaring Forties', where mild-temperature air from the north meets cooler air from the south. Hazards include loss of power and communications, falling trees and poles, fast-flowing currents in streams and rivers, snowstorms, landslips and flooding.

WHAT IS A STORM?

A storm is a disturbance of the atmosphere that can cause strong winds, rain, thunder, lightning, heavy snow and rough seas. A strong wind warning is issued by the MetService when winds of more than 87kph are expected over land. Coastal areas can suffer from storm surges, which are extra-high tides caused by the high winds pushing the sea forward.

Before

    When a strong wind warning is issued:
  • Listen to your radio for information.
  • Bring pets inside if possible.
  • Help clear away anything outside that may become a flying missile in the wind.
    • When a snow warning is issued:
  • Listen to your local radio station for information.
  • Avoid leaving home unless absolutely necessary.
  • If you have to travel, help make sure you are well prepared with snow chains, sleeping bags, warm clothing and essential emergency items.
  • Remind your family to check fuel supplies for wood-burners, gas heaters, barbeques and generators.
  • Bring pets inside if you can and help move stock to shelter.

During

  • Stay inside. If outside find shelter quickly.
  • Close all curtains to slow down flying glass.
  • Stay away from doors and windows. If the wind becomes destructive, shelter further inside the house.
  • Stay away from metal and electrical fixtures.

After

  • Stay indoors and listen to the radio.
  • Avoid dangling and broken power lines, if outside.
