TNRIS (Texas Natural Resources Information System) has launched their new Emergency Resources web site which overlays Doppler weather with a Virtual Earth map for storm tracking. You can also get down to a specific city, by geocoding places in the search box. Track the Hurricane Gustav which has just hit the US coasts.

Hope such satellite imagery from Virtual Earth is provided for all , such as for the recent Floods in Bihar, India.
