A couple of notes. While I haven't covered hurricanes, I've read and talked to those who have.
1) The "smart" crews will find a building in the shape of an L, or ideally a cross. When the hurricane is approaching, they setup in the NE(?) corner of the building. So while you see the destruction behind the reporter, behind the camera could be "safe". After eye passes, then they move to the SW(?) corner. I might have my directions mixed up, but you get the idea.
2) Most (95%+?) of the stations are owned by groups. Those groups will "recruit" staff from other markets to come down and help report, shoot, produce, edit, direct, etc to get the shows on the air. Yes, the reporters should/could do some research, but it's also possible they show up, and get sent immediately out into the area to do their report. So it hasn't "sunk in" where they are/how far from the beach.
3) As far as "why"? Television is a visual medium. Viewers want to SEE what's happening. And "a picture says a thousand words". "Well, just have a camera out there". Of course, that still requires a camera operator. You could put a remote camera somewhere, but you have to A) hope that location is a "visual" location and B) hope that location maintains power and connectivity. A physical crew can move somewhere else if one location is bad.
