WMO World City Forecasts

This WMO project on world city forecasts is to explore the wider exchange and availability of official weather information on the Internet.

In view of this, a WMO-sponsored web site - World Weather Information Service (WWIS) is established as a centralized source on the Internet for media to access official weather information issued by National Meteorological and Hydrological Services (NMHSs) efficiently and effectively.

The WWIS web site is developed and maintained by the Hong Kong Observatory (HKO) of Hong Kong, China.
