Understanding Alerts & Warnings

Preparing for Human Caused Disasters


Terrorist Warnings and Advisories
In the months following 9/11, the White House released a new directive that identified threat levels. This new system is color coded.  It will aid local agencies, and the public, in determining what the appropriate response should be.

From lowest to highest, the levels and colors are:

  • Low Threat: Green
  • Guarded Threat: Blue
  • Elevated Threat: Yellow
  • High Threat: Orange
  • Severe Threat: Red

 

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. Threat conditions may be assigned for the entire Nation, or they may be set for a particular geographic area or industrial sector.

This system is intended to create a common vocabulary, context and structure for an ongoing national discussion about the nature of threats that confront the homeland and the appropriate measures that should be taken in response.

The assignment of a Threat Condition shall prompt the implementation of an appropriate set of Protective Measures. Protective Measures are the specific steps an organization takes to reduce its vulnerability or increase its ability to respond during a period of heightened alert.
