Hurricane Katrina is being watched online around the world, from the perspective of satellites. This image comes from the weather.com site – giving us a sense of the movement of the hurricane over two hours.

At the Web Logg-Ed blog, Will gives educationalists ideas on how to connect students with information on the hurricane using:

Wikipedia, CNN, Flickr, the National Hurricane Center, local press, and bloggers through Technorati.
