The Big Picture posted some astounding photos of the flood waters today.
FP Passport has some amazing satellite photos that show the extent of flooding in Burma in the aftermath of Cyclone Nargis. As we know from Katrina, insufficient official response following a disaster can lead to additional deaths, and Burma has one of the worst governments in the world. The Burmese government is almost certainly more concerned with hiding how bad things are from its own citizens and the rest of the world than it is with actually preventing further loss of life.
Update: As feared, Burma is not admitting aid workers who are ready to help.
