Department of Homeland Security updates National Terrorism Advisory System

DHS logo

Earlier today, the Department of Homeland Security updated the National Terrorism Advisory System, or NTAS, a tool designed to communicate information about terrorist threats by providing timely, detailed information to the American public. As part of the Coast Guard’s commitment to the security of America’s waterways, we are informing you of the change to the NTAS system and providing our readers with the opportunity to add an NTAS widget to your own websites to keep friends, family and neighbors informed of potential threats.

Since 2011, NTAS has featured an advisory system consisting of two types of alerts: Elevated and Imminent. Today, DHS added a third type of advisory, “Bulletins.”

NTAS “Bulletins” will provide information describing broader or more general trends and current developments regarding threats of terrorism. They will share important terrorism-related information with the American public and various partners and stakeholders, including in those situations were additional precautions may be warranted, but where the circumstances do not warrant the issuance of an “elevated” or “imminent” alert. An NTAS Bulletin will summarize the issue and why it is important for public awareness, outline U.S. government counterterrorism efforts and offer recommendations to the public on how it can contribute to the overall counterterrorism effort.

Today, DHS issues it’s first NTAS Bulletin to cover the period of December 16, 2015 to June 16, 2016. The Bulletin contains information related to recent domestic and international terrorist attacks and how the public can assist in preventing future attacks.

An “Elevated Alert” is intended to warn of a credible terrorist threat against the United States and its territories that is general in both timing and potential location such that it is reasonable to recommend implementation of protective measures to thwart or mitigate against an attack.

An “Imminent Alert” is intended to warn of a credible, specific and impending terrorist threat or on-going attack.

Coast Guard Compass has added a National Terrorism Advisory System widget to our website and you can add the widget to your site as an additional means of keeping your loved ones and communities safe.

    Another great advance for the citizens of American. Homeland Security and our Five Military Services as well as FBI, CIA, and other Protectors have another modern tool at their disposal to keep everyone safe.

    Not to be too critical, but your last paragraph has a typo …. ‘National Terrrism Advisory System’. Just a hotel uniform. DPB

    The DHS Facebook page and Twitter account will post alerts when NTAS updates are issued. Additional web developer resources (including API access) can be found on the DHS website.
