The Hong Kong Observatory launches a new 'Digital Weather Forecast' webpage today (23 March 2010), providing weather forecasts in fine spatial and temporal details to the public.  The website is  http://www.hko.gov.hk/dfs/main/dfs_tt_e.html.

The new forecast products show hourly changes in temperature, wind direction and speed at a resolution of 10 kilometres in Hong Kong and the neighbouring Pearl River Estuary region.  They are updated once every morning at about 4:00 a.m. and the forecast period is from 5:00 a.m. the same day to 8:00 a.m. the next day.

Another set of forecast maps is also available for display on a Geographic Information System (GIS) platform.  Users can zoom in, zoom out, animate and overlay other geographic information on the weather forecast maps to better appreciate the weather conditions in their area of interest.
