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.
This global web site presents OFFICIAL weather observations, weather forecasts and climatological information for selected cities supplied by NMHSs worldwide. The NMHSs make official weather observations in their respective countries. Links to their official weather service web sites and tourism board/organization are also provided whenever available. Weather icons are shown alongside worded forecasts in this version to facilitate visual inspection.
The media are welcome to make information presented in this web site available to the public. When doing so, credit to the respective NMHSs should be given.
