A weekly update describing soil moisture patterns across the country to show where dry to extremely dry conditions are occurring or imminent. Regions experiencing significant soil moisture deficits are deemed “hotspots”. Persistent hotspot regions have the potential to develop into drought.

Researchers are studying the moraines around Lake Tennyson to work out why and when the glaciers disappeared.

The annual end-of-summer snowline survey of more than 50 South Island glaciers has revealed continued loss of snow and ice. Last week, scientists from NIWA, Victoria University of Wellington, and Department of Conservation took thousands of aerial photographs of glaciers. Some of them are used to build 3D models that track ice volume changes.

This week’s torrential rains have set a new national rainfall record.
