A good general evaluation, denuseri. But it should be noted that these effects which are noted are very generalized, and will not necessarily apply to any specific individuals. People tend to deal with such things in different ways, as noted in your piece.
In my own limited experience, dealing with the devastation of Hurricane Hugo in 1989, the range of effects upon people was very widespread. Some people tended to panic before hand, rushing out to the stores and buying up things which they really did not need, making things difficult for those who really did have the need. During the height of the storm, naturally, people were hunkered down in their homes or shelters, as was my family. Believe me, sitting in our home, in the dark when the power went out, listening to the wind howling around us, hearing the trees falling, feeling them strike the house, was a terrifying enough experience. Listening to the radio as well-meaning but clueless announcers blathered on about whole towns being wiped out (close, perhaps, but not quite true) and hospitals collapsing (completely false) only made things worse.
Getting out in the morning, after the storm had passed, wasn't much better. There were trees down everywhere. It was almost impossible to drive for as much as a mile without running into downed trees and power lines. But the prevailing attitude of those I saw was relief at surviving and a readiness to get to work putting things right again. For seemingly endless days the sounds of chain saws permeated the area. There was very little panic or bad behavior.
In the aftermath, again the range of effects were broad. For my part, I have little residual anxiety over the incident. But I still notice myself paying more attention to the wind, especially during thunderstorms. Others I know grow anxious whenever there is a thunderstorm warning. And at least one person I know has to take a sedative to make it through the storms.
