The only solution is multiple solutions. Commercial radio has a threshold of how small a market can be before it isn't worth it any longer, noncommercial radio (including NOAA weather radio stations) can fill in those gaps but require people to have the receivers handy, and more people carry cell phones than radios nowadays but cell service isn't absolutely everywhere. We can improve each of those individual technologies, but no single technology is going to become the only answer.
