I believe ZERO any media outlet tells me (anyone).
Weather? I will give it a listen (most of the time they spend so much time convoluting the story that you can't figure out WTH you just listened to for the last 3 minutes, and all you wanted to know if it was going to rain, snow, sleet or sun shine that day.
As far as days ahead, yeah, pay attention for 72-96 hours ahead and follow that. You'll be able to make a decision about what you need to about 36 hours in advance, 70% of the time.
Otherwise, they are lying 99% of the time.
