The Associated Press: Color-coded terror warnings to be gone by April 27 WASHINGTON (AP) By the end of April, terror threats to the U.S. will no longer be described in shades of green, blue, yellow, orange and red, The Associated Press has learned. The nation's color-coded terror warning system will be phased out beginning this week, according to government officials familiar with the plan. The officials requested anonymity to speak ahead of an announcement scheduled Thursday by Homeland Security Secretary Janet Napolitano. The Homeland Security Department and other government agencies have been reviewing the Homeland Security Advisory System's usefulness for more than a year. One of the most notable changes to come: The public will no longer hear automated recordings at U.S. airports stating that the threat level is orange.
