I think the federal government needs to come up with a better way to warn people. I think the new name should convey exactly what it's supposed to do. It would improve the existing system that the NWS uses, combined with other technologies. It would be named:

Office of
Homeland
Security
Hazardous
Incident
Terminology
Rapid
Uniform
Notification

In the spirit of the P.A.T.R.I.O.T. A.C.T.
