Reelyreal, being on by 6pm when the tornado strikes at 4:30p is really unacceptable. The damage is done and the lives have already been lost.
A live jock could've given frequent warnings, location of the storm, areas hit, what damage it's done already, where to go for shelter, traffic conditions etc. Any jock worth their salt would've have just read the EAS alert verbatum. They would've had the local news TV station on in the studio and gathered info from there as well. The EAS sounds ONCE for a tornado warning and that's it. So if someone doesn't catch it and no new warnings are issued, that's all they'll get. Simply saying that you can rely on the EAS box doesn't work.
Stations are licensed to serve the public / community. It doesn't get any more real than telling the market you serve that a deadly tornado is on the way! Clear Channel didn't do it. Plain and simple. I say solicit the FCC and have them fined.
