Cyclone Gabrielle: New Zealand braces for storm after record floods

Preparations are underway in New Zealand for a severe storm that threatens to hit parts of the country already damaged by deadly flooding.

Cyclone Gabrielle is expected to hit the country's North Island from Saturday night - potentially bringing strong winds and further heavy rain.

Residents have been told to ensure they have enough supplies to last three days in case they are trapped at home.

Tens of thousands of sandbags have been distributed there due to concerns the sodden ground and weakened infrastructure have made homes more vulnerable to flooding.

Photographs and videos posted on social media showed long queues at supermarkets and bare shelves as people prepared for more severe weather.

Air New Zealand, the national carrier, has cancelled several domestic flights ahead of the cyclone's arrival.

Local media have reported that New Zealand's most northern region, Northland, has already begun to experience high winds.

Cyclone Gabrielle has been downgraded from a category three storm to a category two, meaning less destructive winds are now expected.

However, forecasters have warned that they could still be strong enough to damage trees and power lines and that enough rain could fall to cause further flooding and landslides in the coming days.

The Coromandel Peninsula and the Tairāwhiti/Gisborne region, which were also affected by the recent torrential rain, have been placed under the most serious weather alert.

Residents in flood-prone areas have been told to prepare to evacuate.

Meanwhile, the Australian Bureau of Meteorology has said that conditions on the remote territory of Norfolk Island have begun to deteriorate because of Cyclone Gabrielle.

The island, which lies north of New Zealand, has also been placed under a red alert. Residents have been warned to stay indoors and to find the strongest part of their homes under which to take shelter.

Only three cyclones have come within a 50km (31 mile) range of the island in the past 30-40 years.
