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.
