Hurricane Sandy and God's Judgment
One thing is easy to predict - after any great national disaster a self-appointed spokesman for God will declare that this is God's judgment.
Every single death is a direct consequence of sin. Many sins have direct, specific consequences, but as soon as Adam sinned, death entered the world. So you could say that the deaths caused by hurricane Sandy were caused by lying, stealing, lust, hate, etc., and you would be perfectly correct.
Aligning a specific catastrophe with a specific sin (or group thereof) is considerably harder, particularly because, in the Bible, the exact consequences of catastrophes were prophesied beforehand--a feat which none of these "self-appointed spokesmen" have been able to manage. Plagues, famine, drought, conquest, pestilence--they were all explicitly prophesied prior to their occurrence. To the best of my knowledge, the only Biblical catastrophe that wasn't prophesied ahead of time was the storm that nearly swamped Jonah's boat.
Finally, a temporal judgment is not what we should be afraid of. While nothing to sneeze at, God's wrath in the form of a hurricane is far superior to God's wrath in the form of hell. As St. Augustine argued, the suffering and death in this world should make us hate the sin that caused it.
