WMO Register of Alerting Authorities
The international Register of Alerting Authorities was set up by the World Meteorological Organization (WMO) and the International Telecommunication Union (ITU). Each WMO Permanent Representative (PR) maintains entries for their nation. The PR represents the entire nation and should register all nationally recognized alerting authorities. The Register is maintained by the WMO Public Weather Services Delivery (PWSD) programme.
