Read about the New National Terrorism Advisory System. 

Overview

The National Terrorism Advisory System, or NTAS, replaces the color-coded Homeland Security Advisory System (HSAS). This new 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.

National and Pennsylvania Homeland Security Advisory systems have been put into place to provide information on warnings and actual events involving terrorist acts that may occur.

Imminent Threat Alert

Warns of a credible specific and impending terrorist threat against the United States.

Elevated Threat Alert
