HOMELAND SECURITY ADVISORY SYSTEM

The Homeland Security Advisory System is used to advise the public of changes in the threat level for possible terrorist attacks. The color-coded system indicates probability of a terrorist attack: green = low, blue = guarded, yellow = elevated, orange = high, and red = severe. Also the advisories are targeted for geographic regions and/or sectors (such as mass transit, aviation, etc.).For the latest information on the Homeland Security Advisory System, see this link:
