Myth-busting ultraviolet radiation

Written by Wayde Beckman from the Health Sponsorship Council, on 11 November 2010

Challenges in forecasting severe weather

The severe weather in various parts of the country over the last week or so has presented a significant challenge to some communities – and to staff at MetService as well.

The message needs to be relevant and clear – not always an easy task, given that users of weather information have such diverse needs.
