IPAWS: The Integrated Public Alert and Warning System
2
History of Emergency Alerts
CONELRAD
EBS
EAS
Limitations
In the past, all alerts came through radio and television transmission
Alerts were audio-only
Alerts were only in English
Daisy-chain limitations
3
What is the Integrated Public Alert and Warning System (IPAWS)?
IPAWS will take the existing Emergency Alert System (EAS) and add new ways to warn people of imminent threats
The public will receive alerts via
– Cell phones - Radio
– Email - Residential telephone
– Television - others TBD
The mission is to ensure the President can communicate with State, Local, and Tribal governments and the public in times of war or national emergency
IPAWS capabilities will also be available to emergency managers

IPAWS Architecture
One message will reach the public through every available communication path
– A message can originate at the Federal, State, or Local level
– The message will go to the IPAWS aggregator—servers that will gather the messages and authenticate them, then
– The message will go through multiple distribution paths to reach every available communications device
IPAWS is developing standards and protocols to increase interoperability among alert and warning systems

Progress to Date
The first standard IPAWS has developed is called the Common Alerting Protocol (CAP)– Allows a single alert message to be routed over many systems– Can easily work with language translation software for non-English
speakers, hearing impaired and other special audiences– IPAWS working to upgrade participating systems to be CAP compatible
• NOAA• Cellular broadcast
For cell phone alerts, the interface is finished that allows a message to go from the IPAWS system to the cell phone users

GTAS is a joint pilot project between NOAA and FEMA providing Emergency Managers with a new software tool;
Integrates NOAA’s advanced weather information and warning infrastructure with FEMA IPAWS dissemination systems;
It’s a JAVA based system with a graphical user interface.
Provides targeted warnings to the public in event of toxic release via reverse 911 technology;

How GTAS Works?
Provides targeted warnings to the public in event of toxic release via reverse 911 technology;
Integrates NOAA’s advanced weather information and warning infrastructure with FEMA IPAWS dissemination systems;
Operational in community EOC and Weather Field Office;
Interface to Commercial Mobile Alert System via CAP messages.

GTAS Provides Emergency Manager a Easy to Use Tool
GTAS provides information the emergency manager needs to quickly identify the public that is at risk;
Uses a simple graphical user interface for system managers;
Provides collaboration tools, so the EM can work with the experts at a WFO to clarify the information that is being presented;
