Maps: The Impact of Hurricane Katrina - New York Times

Today is 'Blog for Hurricane Relief' day, devoted to raising awareness and funds for those hit by Katrina. I stick by the American Red Cross as the charity I would most likely suggest, given the scope of the disaster and a need to get money and materials (but mostly money, since coordination of materials by smaller organisations is probably a nightmare). If you're like me and don't have a way to donate online, check for institutions in your area accepting cash for the relief. In Lexington, Central Bank locations are accepting donations for the Red Cross, for example. Another way to help is through the KatrinaHelp Wiki, an effort modelled after the TsunamiHelp Wiki that helped coordinate information during that disaster.
