Why is the Register necessary?
Aggregators and other intermediaries typically lack direct knowledge needed to distinguish an authoritative source of alert messages
This lack becomes more critical as alerting makes more use of large public networks
The Register of Alerting Authorities is a tool to address this gap
Each Register entry indicates a particular source of alert messages designated by a WMO Member as authoritative, for particular categories of hazards over a particular area

How are the Register entries maintained?
WMO letter to all PRs in 2009 describing the Register; recent follow-up letter
PRs were requested to designate an editor to maintain Register records for the Member’s alerting authorities
The designated editor is approved by WMO/PWS and selects a password
Each editor maintains Register entries on behalf of the Member
The Register application is being redeveloped to operate at Hong Kong Observatory and will be backed up by South Africa Weather Service
