    FM is more affected by physical barriers (buildings, etc.). Range is around 30 miles. AM range is around 100 miles during the day and further at night.

    Don’t states with frequent hurricanes still recommend switching to AM in the event of disaster? There are a lot of situations where cell phones or FM may not work, but you could get an AM signal.

      I’m not sure what people would do with normal radios, but people in a severe weather area might own a weather radio that gets alerts from NOAA, and that’s on VHF, though they usually have AM/FM as well. I lived in tornado alley for a while and yeah, we would listen to whatever we could receive (FM in more populated areas, but AM when way out in the sticks) and we had a NOAA radio too.
