I'll add here that the media, especially local media, is culpable as well. There are plenty of scenes of devastation at landfall, but local news, not having reporters in those areas, feels the need to fill gaps with local scenes. A tree down on I-4. A reporter standing on the beach with her raincoat flapping in a 30mph wind. A garbage can rolling down the street.I've lived down here going on 30 years now. What happens is, and I'm not saying these people are right, is that there's that one time a really bad hurricane was headed right towards them, forecasting total destruction, and it misses. They get the belief that because it happened that one time, its the rule rather than the exception. I see it a lot with residents of the Tampa Bay area. Charley back in '04 was going to devastate Tampa Bay. At the last minute, like 4 hours before landfall, it veered south. So a lot of folks in Tampa didn't evacuate for this one. This one, too, veers south. So, I guarantee the next time NHC predicts a Tampa landfall, even fewer people will leave the area. It become a mindset of "its not going to be as bad as they say. They are sensationalizing it. It never follows the forecast track."
Like I said, not condoning it, I evacuate for anything CAT2 and up, but just saying where the mentality comes from.
People start to think "this is what a Category 4 storm is? I'll never evacuate for something like that."
