The Alaska Volcano Observatory has a webcam on a Chevron oil platform that offers a great view when weather permits [right, static photo of Mt. Redoubt in clear skies]
A number of geobloggers and websites are following this closely with great detail. I won't attempt to duplicate their work - a good source for updates is the Volcanism Blog.
