Today is day 6 of some people still not having power after the recent barrage of nearly hurricane-strength storms along the southern US.

Those cheap AM/FM/weather radios that run off AA batteries are invaluable.

Phones are great for emergency notifications but I think AM would be better for long-term sustained emergencies. It’s a highly highly unlikely event though.

AM is more effective for true emergency situations where civilization has broken down because the section of the spectrum it uses naturally propagates further. You can hear an AM station over a much larger area than an FM station.

Yes you would have to be listening to an AM station. I almost never listen to the radio, but when I do it is an FM station. The EBS breaks into that when any emergency arises.
