Cloud cover
The weather symbols were replaced in May 2005 after 29 years and 9 months on air by a controversial format as the forecast underwent another redesign, with the flat map replaced by a 3D globe, and weather conditions shown by coloured areas. Cloud cover is indicated by the brightness of the map, while rain and snow are indicated by animated blue and white areas respectively. The graphics are provided by Weatherscape XT, which was developed by the commercial arm of the New Zealand Metservice.
