To be fair, free broadcast tv and radio is still a thing, and they are an integral part of the US’s disaster alert system. With the right equipment (read: basic cheap radio available almost everywhere), you can still listen to weather information (both general and severe) directly from the horse’s mouth 24/7 for free.
In a disaster situation, these services will still stand because they require less infrastructure per person reached than is required to deliver high-speed internet to the same number of people.
These services still exist, and will continue to, but the knowledge of them has atrophyed from disuse. They won’t go away, they’ve just been replaced in general usage because of the convenience that the internet provides us.
TL;DR: Get you a weather radio, get free weather for the life of the equipment. Even if it’s not your daily driver, get one anyways, because you’ll be able to hear the most relevant info in the worst situation.
I have a weather radio. Every time I turn it on during an intense storm, it gives me very little useful information. It tells me something like “a tornado has been sited in your area [without defining what that means], seek shelter immediately.” After the last massive storm ended where so many fallen trees destroyed homes, took out power lines, made roads impassable, etc. and the cell network was getting jammed by so many users, do you know what information the two local TV stations and the local radio stations were offering?
Fuck. All.
But hey, one of the two TV stations did relay the fact that the state had made a disaster declaration half a day after the declaration was made.
Those services exist, but they’re almost useless.
