In an article on CNN, Biloxi Mayor A.J. Holloway told the Biloxi Sun Herald referred to Katrina in the following way:

This is our tsunami

Which, to me, is a ridiculous statement. The Southern US had days to come to prepare for the storm that was coming and evacuate the most vulnerable areas. The residents of the Indian Ocean region, where the December 26, 2004, tsunami that killed more than 226,000 hit, had moments to save themselves. They had no idea the tsunami was coming until they saw the wave.

Mayor Holloway, your comparison is faulty and rather insensitive. It shows your complete ignorance of world events and a complete lack of a scientific understanding of weather.
