I don't think you understand how the Emergency Alert System works and most if not all of what you said is incorrect. How do you think the EAS alerts are sent to your station of choice? (It would be the NWS issuing the alert for weather not FEMA.) There are a few dozen stations known as Primary Entry Points where the signals originate. Guess what the overwhelming majority of these stations are? AM.

All other stations (like most FM) have decoders that are tuned to and listen to other stations for the alert signal. They operate simply as relays in a tree. So no, AM is not going away, not now, not ever, lazy EV engineers be damned.
