Unified system for public announcements. Public announcements of threat advisories and alerts help deter terrorist activity, notify law enforcement and State and local government officials of threats, inform the public about government preparations, and provide them with the information necessary to respond to the threat.
State and local officials will be informed in advance of national threat advisories when possible. The Attorney General will develop a system for conveying relevant information to Federal, State, and local officials, and the private sector expeditiously. Heightened Threat Conditions can be declared for the entire nation, or for a specific geographic area, functional or industrial sector. Changes in assigned Threat Conditions will be made when necessary.
