I've experienced (as an adult) blizzards, hurricanes, and tornadoes. The first made me nervous enough to stay where I was (which was a good decision - I would have been stuck in traffic) the second scared me, but I did as much as I could to stay safe. The third terrified me because I knew that even though my children and I were huddled in the safest room in our house, covered with cushions and blankets, if we took a direct hit we might not survive. The tornado passed within 1/2 mile of our house. Once you have seen the warning signs (the sky a strange green/gray color, freight train noise that sounds different from the thunder, and a perceptible change in the way the air felt) you will never forget them.
