The higher the Threat Condition, the greater the risk of a terrorist attack. Risk includes both the probability of an attack occurring and its potential gravity. The Attorney General in consultation with the Secretary of Homeland Security shall assign threat conditions for the Homeland Security Advisory System. Threat Conditions may be assigned for the entire nation, or they may be set for a particular geographic area or industrial sector. Assigned Threat Conditions shall be reviewed at regular intervals to determine whether adjustments are warranted.
