I do know the Weather Channel has been criticized in the past for purposely standing somewhere that tends to make the storm look as bad as possible when 180 degrees behind them it looked totally different. I watched a bit of the Florida hurricane coverage this evening and agree with you that the 24 hr non-stop coverage seems a bit over the top for me. One guy was standing in some parking garage showing how the water was rising while another was standing in the open with the wind howling in his face. Standing out in the open during a hurricane seems needlessly dangerous since you easily get hit by flying debris.
While I think the weather coverage ahead of these storms is good to create awareness and encourage people to make plans/evacuate/etc., the live/never-ending coverage is a bit much and doesn't accomplish much. If you live there you should have already evacuated and if you haven't by now it is too late/dangerous to be on the roads that are rapidly flooding.
During one of the other recent hurricanes, some of those broadcasting seemed to have NO idea where they were and talked like they just showed up and someone handed them a microphone to broadcast live. One of them was in some parking lot of a hotel and didn't even know how far they were from the ocean. What that accomplished I had NO idea.
After the storm has passed there will likely again be days of coverage when the reporter stands next to a pile of rubble and goes on about how bad the storm was. What purpose that serves isn't clear to me either.
