The National Terrorism Advisory System, or NTAS, replaces the color-coded Homeland Security Advisory System (HSAS). This system will more effectively communicate information about terrorist threats by providing timely, detailed information to the public, government agencies, first responders, airports and other transportation hubs, and the private sector.
It recognizes that Americans all share responsibility for the nation's security, and should always be aware of the heightened risk of terrorist attack in the United States and what they should do.
Visit the NTAS site at http://www.dhs.gov/national-terrorism-advisory-system to learn more.
Recently, US DHS has improved this system by adding the new advisory level of "Bulletin." Bulletins, when issued, are intended to provide the American public with more flexible, timely and useful information regarding terrorist threats to Our Homeland.
For more information regarding the new NTAS Bulletins read the NTAS Bulletin Fact Sheet.
For answers to some Frequently Asked Questions regrading the National Terrorism Alert System read the NTAS FAQs.
You can sign up with US DHS to receive NTAS alerts by email, Facebook and/or Twitter.
