Warning systems are to provide warnings about significant hazards with the potential to affect human populations, geographical areas, or social or economic activities.

This plan does not cover—
localised, long-term, or slowly-evolving threats; or
the local actions and procedures required to disseminate or respond to warnings.

The effectiveness of a warning depends on its delivery and receipt, recipients’ understanding of what they should do under the particular threats, and readiness and response at all levels.
